weaken the stability of buildings and infrastructure, posing serious risks to their structural integrity. Therefore, this study aims to understand how oil contamination affects the torsion behavior of model steel piles at different soil densities. This research is crucial for evaluating the structural integrity and stability of piles in oil-contaminated environments. Clean sand samples and heavy motor oil were mixed in amounts ranging from 0 to 6% of the soil's dry weight. The mixture was thoroughly mixed to ensure uniform distribution of the oil throughout the sandy soil for simulating the field conditions. In these investigations, the relative densities (Dr), pile slenderness ratio (Lp/Dp), oil content (O.C%), and contaminated sand layer thickness (LC) were all different. Also, the paper presents an analysis of piles that are loaded both vertically and torsionally. The findings demonstrated that the pre-applied torsion load led to a decrease in the vertical bearing ability of the pile. Also, at Dr = 80%, the ultimate vertical load under combined load at constant torsional load T = (1/3Tu, 2/3Tu, and Tu) in the cases of (Lc/Lp) = 0.5 and (Lp/Dp) =13.3 was found to be reduced by (1.48, 2.78, and 4.15%) less than piles under independent vertical load, respectively so it is crucial to consider the torsion load during pile design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=torsion-vertical%20load" title="torsion-vertical load">torsion-vertical load</a>, <a href="https://publications.waset.org/abstracts/search?q=oil-contaminated%20sand" title=" oil-contaminated sand"> oil-contaminated sand</a>, <a href="https://publications.waset.org/abstracts/search?q=twist%20angle" title=" twist angle"> twist angle</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20pile" title=" steel pile"> steel pile</a> </p> <a href="https://publications.waset.org/abstracts/180837/experimental-studies-of-the-response-of-single-piles-under-torsional-and-vertical-combined-loads-in-contaminated-sand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180837.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2605</span> High-Voltage Resonant Converter with Extreme Load Variation: Design Criteria and Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20A.%20Pomilio">Jose A.

This paper considers applications in which the load (resistive) has an unpredictable behavior, changing from open to short-circuit condition faster than the output voltage control loop could react. In this context, to avoid over voltage and over current situations, that could damage the converter, the transformer or the load, it is necessary to find an operation point that assure the desired output voltage in spite of the load condition. This can done adjusting the frequency response of the transformer adding an external inductance, together with selecting the switching frequency to get stable output voltage independently of the load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-voltage%20transformer" title="high-voltage transformer">high-voltage transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=resonant%20converter" title=" resonant converter"> resonant converter</a>, <a href="https://publications.waset.org/abstracts/search?q=soft-commutation" title=" soft-commutation"> soft-commutation</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20inductance" title=" external inductance"> external inductance</a> </p> <a href="https://publications.waset.org/abstracts/11524/high-voltage-resonant-converter-with-extreme-load-variation-design-criteria-and-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11524.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">481</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2604</span> Investigating Safe Operation Condition for Iterative Learning Control under Load Disturbances Effect in Singular Values</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20A.%20Alsubaie">Muhammad A.

The presented work discusses the controller previously designed, highlights the disturbance problem, finds new conditions using singular value principle to assure safe operation conditions with error convergence and reference tracking under the influence of load disturbance. It is known that periodic disturbances can be represented by a delay model in a positive feedback loop acting on the system input. This model can be manipulated by isolating the delay model and finding a controller for the overall system around the delay model to remedy the periodic disturbances using the small signal theorem. The overall system is the base for control design and load disturbance investigation. The major finding of this work is the load disturbance condition found which clearly sets safe operation condition under the influence of load disturbances such that the error tends to nearly zero as the system keeps operating trial after trial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iterative%20learning%20control" title="iterative learning control">iterative learning control</a>, <a href="https://publications.waset.org/abstracts/search?q=singular%20values" title=" singular values"> singular values</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20feedback" title=" state feedback"> state feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20disturbance" title=" load disturbance"> load disturbance</a> </p> <a href="https://publications.waset.org/abstracts/108485/investigating-safe-operation-condition-for-iterative-learning-control-under-load-disturbances-effect-in-singular-values" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108485.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2603</span> Load Forecasting Using Neural Network Integrated with Economic Dispatch Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariyam%20Arif">Mariyam Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Ye%20Liu"> Ye Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Israr%20Ul%20Haq"> Israr Ul Haq</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahsan%20Ashfaq"> Ahsan Ashfaq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High cost of fossil fuels and intensifying installations of alternate energy generation sources are intimidating main challenges in power systems. Making accurate load forecasting an important and challenging task for optimal energy planning and management at both distribution and generation side. There are many techniques to forecast load but each technique comes with its own limitation and requires data to accurately predict the forecast load. Artificial Neural Network (ANN) is one such technique to efficiently forecast the load. Comparison between two different ranges of input datasets has been applied to dynamic ANN technique using MATLAB Neural Network Toolbox. It has been observed that selection of input data on training of a network has significant effects on forecasted results. Day-wise input data forecasted the load accurately as compared to year-wise input data. The forecasted load is then distributed among the six generators by using the linear programming to get the optimal point of generation. The algorithm is then verified by comparing the results of each generator with their respective generation limits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title="artificial neural networks">artificial neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=demand-side%20management" title=" demand-side management"> demand-side management</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20dispatch" title=" economic dispatch"> economic dispatch</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20programming" title=" linear programming"> linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20generation%20dispatch" title=" power generation dispatch"> power generation dispatch</a> </p> <a href="https://publications.waset.org/abstracts/100218/load-forecasting-using-neural-network-integrated-with-economic-dispatch-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100218.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2602</span> Improving Load Frequency Control of Multi-Area Power System by Considering Uncertainty by Using Optimized Type 2 Fuzzy Pid Controller with the Harmony Search Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Mahmudizad">Mehrdad Mahmudizad</a>, <a href="https://publications.waset.org/abstracts/search?q=Roya%20Ahmadi%20Ahangar"> Roya Ahmadi Ahangar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the method of designing the type 2 fuzzy PID controllers in order to solve the problem of Load Frequency Control (LFC).

It is due to the low tensile strength of masonry, the mortar connection between the brick units. URM structures are still widely used in the world as an infill wall and commonly constructed with door and window openings. This research aimed to investigate the behavior of URM wall with openings when horizontal load acting on it and developed load-drift relationship of the wall. The finite element (FE) method was chosen to numerically simulate the behavior of URM with openings. In this research, ABAQUS, commercially available FE software with explicit solver was employed. In order to ensure the numerical model can accurately represent the behavior of an URM wall, the model was validated for URM wall without openings using available experimental results. Load-displacement relationship of numerical model is well agreed with experimental results. Evidence shows the same load displacement curve shape obtained from the FE model. After validating the model, parametric study conducted on URM wall with openings to investigate the influence of area of openings and pre-compressive load on the horizontal load capacity of the wall. The result showed that the increasing of area of openings decreases the capacity of the wall in resisting horizontal loading. It is also well observed from the result that capacity of the wall increased with the increasing of pre-compressive load applied on the top of the walls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=masonry%20constructions" title="masonry constructions">masonry constructions</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20at%20earthquake" title=" performance at earthquake"> performance at earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=MSJC-08%20%28ASD%29" title=" MSJC-08 (ASD)"> MSJC-08 (ASD)</a>, <a href="https://publications.waset.org/abstracts/search?q=bearing%20wall" title=" bearing wall"> bearing wall</a>, <a href="https://publications.waset.org/abstracts/search?q=tie-column" title=" tie-column"> tie-column</a> </p> <a href="https://publications.waset.org/abstracts/53817/understanding-seismic-behavior-of-masonry-buildings-in-earthquake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53817.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">252</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2600</span> New Approach for Load Modeling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Slim%20Chokri">Slim Chokri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Load forecasting is one of the central functions in power systems operations. Electricity cannot be stored, which means that for electric utility, the estimate of the future demand is necessary in managing the production and purchasing in an economically reasonable way. A majority of the recently reported approaches are based on neural network. The attraction of the methods lies in the assumption that neural networks are able to learn properties of the load. However, the development of the methods is not finished, and the lack of comparative results on different model variations is a problem. This paper presents a new approach in order to predict the Tunisia daily peak load. The proposed method employs a computational intelligence scheme based on the Fuzzy neural network (FNN) and support vector regression (SVR). Experimental results obtained indicate that our proposed FNN-SVR technique gives significantly good prediction accuracy compared to some classical techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title="neural network">neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20forecasting" title=" load forecasting"> load forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20inference" title=" fuzzy inference"> fuzzy inference</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20modeling%20and%20rule%20extraction" title=" fuzzy modeling and rule extraction"> fuzzy modeling and rule extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20regression" title=" support vector regression"> support vector regression</a> </p> <a href="https://publications.waset.org/abstracts/21065/new-approach-for-load-modeling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21065.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">435</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2599</span> Lessons from Vernacular Architecture for Lightweight Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Taghdiri">Alireza Taghdiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Ghanbarzade%20Ghomi"> Sara Ghanbarzade Ghomi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the gravity load reduction in the structural and non-structural components, the lightweight construction will be achieved as well as the improvement of efficiency and functional specifications. The advantages of lightweight construction can be examined in two levels. The first is the mass reduction of load bearing structure which results in increasing internal useful space and the other one is the mass reduction of building which decreases the effects of seismic load as a result. In order to achieve this goal, the essential building materials specifications and also optimum load bearing geometry of structural systems and elements have to be considered, so lightweight materials selection particularly with lightweight aggregate for building components will be the first step of lightweight construction. In the next step, in addition to selecting the prominent samples of Iran's traditional architecture, the process of these works improvement is analyzed through the viewpoints of structural efficiency and lightweighting and also the practical methods of lightweight construction have been extracted. The optimum design of load bearing geometry of structural system has to be considered not only in the structural system elements, but also in their composition and the selection of dimensions, proportions, forms and optimum orientations, can lead to get a maximum materials efficiency for loads and stresses bearing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gravity%20load" title="gravity load">gravity load</a>, <a href="https://publications.waset.org/abstracts/search?q=light-weighting%20structural%20system" title=" light-weighting structural system"> light-weighting structural system</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20bearing%20geometry" title=" load bearing geometry"> load bearing geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20behavior" title=" seismic behavior"> seismic behavior</a> </p> <a href="https://publications.waset.org/abstracts/19932/lessons-from-vernacular-architecture-for-lightweight-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19932.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">544</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2598</span> Effect of Adding Horizontal Steel Bracing System to Ordinary Moment Steel Frames Subjected to Wind Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Al-Qaryouti">Yousef Al-Qaryouti</a>, <a href="https://publications.waset.org/abstracts/search?q=Besan%20Alagawani"> Besan Alagawani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main concern of this study is to evaluate the effect of adding horizontal steel bracing system to ordinary moment resisting steel frames subjected to wind load. Similar frames without bracing systems are also to be compared. A general analytical study was carried out to obtain the influence of such system in resisting wind load. Linear static analysis has been carried out using ETABS software by applying fixed wind load defined according to ASCE7-10 for three-, six-, nine-, and twelve-story ordinary moment steel frame buildings including and not including horizontal steel bracing system. The results showed that the lateral drift due to wind load decreased by adding horizontal bracing system. Also, the results show that effect of such system is more efficient to low-rise buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=horizontal%20bracing%20system" title="horizontal bracing system">horizontal bracing system</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20moment%20frames" title=" steel moment frames"> steel moment frames</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20load%20resisting%20system" title=" wind load resisting system"> wind load resisting system</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20static%20analysis" title=" linear static analysis"> linear static analysis</a> </p> <a href="https://publications.waset.org/abstracts/52051/effect-of-adding-horizontal-steel-bracing-system-to-ordinary-moment-steel-frames-subjected-to-wind-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52051.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2597</span> A Genetic Algorithm for the Load Balance of Parallel Computational Fluid Dynamics Computation with Multi-Block Structured Mesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chunye%20Gong">Chunye Gong</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming%20Tie"> Ming Tie</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Liu"> Jie Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Weimin%20Bao"> Weimin Bao</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinbiao%20Gan"> Xinbiao Gan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shengguo%20Li"> Shengguo Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo%20Yang"> Bo Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuguang%20Chen"> Xuguang Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tiaojie%20Xiao"> Tiaojie Xiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Sun"> Yang Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Large-scale CFD simulation relies on high-performance parallel computing, and the load balance is the key role which affects the parallel efficiency.

The advantages of lightweight construction can be examined in two levels. The first is the mass reduction of load bearing structure which results in increasing internal useful space and the other one is the mass reduction of building which decreases the effects of seismic load as a result. In order to achieve this goal, the essential building materials specifications and also optimum load bearing geometry of structural systems and elements have to be considered, so lightweight materials selection particularly with lightweight aggregate for building components will be the first step of lightweight construction. In the next step, in addition to selecting the prominent samples of Iran's traditional architecture, the process of these works improvement is analyzed through the viewpoints of structural efficiency and lightweighting and also the practical methods of lightweight construction have been extracted. The optimum design of load bearing geometry of structural system has to be considered not only in the structural system elements, but also in their composition and the selection of dimensions, proportions, forms and optimum orientations, can lead to get a maximum materials efficiency for loads and stresses bearing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gravity%20load" title="gravity load">gravity load</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweighting%20structural%20system" title=" lightweighting structural system"> lightweighting structural system</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20bearing%20geometry" title=" load bearing geometry"> load bearing geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20behavior" title=" seismic behavior"> seismic behavior</a> </p> <a href="https://publications.waset.org/abstracts/18158/applied-methods-for-lightweighting-structural-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18158.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">522</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2595</span> Slope Stability Considering the Top Building Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Micke%20Didit">Micke Didit</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiwen%20Zhang"> Xiwen Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Weidong%20Zhu"> Weidong Zhu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Slope stability is one of the most important subjects of geotechnics. The slope top-loading plays a key role in the stability of slopes in hill slope areas. Therefore, it is of great importance to study the relationship between the load and the stability of the slope. This study aims to analyze the influence of the building load applied on the top of the slope and deduces its effect on the slope stability. For this purpose, a three-dimensional slope model under different building loads with different distances to the slope shoulder was established using the finite-difference analysis software Flac3D. The results show that the loads applied at different distances on the top of the slope have different effects on the slope stability. The slope factor of safety (fos) increases with the increase of the distance between the top-loading and the slope shoulder, resulting in the decrease of the coincidence area between the load-deformation and the potential sliding surface. The slope is no longer affected by the potential risk of sliding at approximately 20 m away from the slope shoulder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20load" title="building load">building load</a>, <a href="https://publications.waset.org/abstracts/search?q=finite-difference%20analysis" title=" finite-difference analysis"> finite-difference analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=FLAC3D%20software" title=" FLAC3D software"> FLAC3D software</a>, <a href="https://publications.waset.org/abstracts/search?q=slope%20factor%20of%20safety" title=" slope factor of safety"> slope factor of safety</a>, <a href="https://publications.waset.org/abstracts/search?q=slope%20stability" title=" slope stability"> slope stability</a> </p> <a href="https://publications.waset.org/abstracts/150072/slope-stability-considering-the-top-building-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150072.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">178</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2594</span> A Study of Cracking Behavior in Concrete Beams Reinforced With Two Different Grades of Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nihal%20Abdel%20Hamid%20Taha">Nihal Abdel Hamid Taha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Crack evaluation of flexure reinforced concrete (RC) member is considered an important step in the design process, since the formation of concrete cracks depends on the possibility of exposure to various conditions(pollution, humidity,..etc.). Because of the disparity between different grades of steel in the service load stresses, this affects the cracking behavior. This paper is concerned with the crack pattern and cracking load for concrete beams with T-section reinforced with two different grades of steel at the service load levels stages up to ultimate load. A practical program has been put up to investigate the difference between reinforced steel bars with yield strength 420 N/mm2 and 500 N/mm2 through six T-section reinforced beams. The beams were tested under static- monotonic two– point service loading up to ultimate failure under flexural stresses. The influence of parameters such as clear concrete cover and concrete compressive strength are considered for each of the two grades of steel used. Cracking load, spacing and width were determined. The experimental results demonstrated that increasing the concrete strength results in both of cracking and ultimate load increase, while no significant difference in yield load for the two steel grades used. It has also become obvious, that the number of cracks was more for the lower steel strength, which is followed by decrease in crack width and spacing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RC%20beams" title="RC beams">RC beams</a>, <a href="https://publications.waset.org/abstracts/search?q=cracking%20behavior" title=" cracking behavior"> cracking behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20stress" title=" steel stress"> steel stress</a>, <a href="https://publications.waset.org/abstracts/search?q=crack%20width" title=" crack width"> crack width</a>, <a href="https://publications.waset.org/abstracts/search?q=crack%20spacing" title=" crack spacing"> crack spacing</a> </p> <a href="https://publications.waset.org/abstracts/182397/a-study-of-cracking-behavior-in-concrete-beams-reinforced-with-two-different-grades-of-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182397.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">62</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2593</span> The Load Balancing Algorithm for the Star Interconnection Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20M.%20Awwad">Ahmad M.

The objective is to identify a prespecified number of line outages that lead to the maximum interruption of power generation and load at the transmission level, subject to the active power-flow model, the load and generation capacity of the buses, and the phase-angle limit across the transmission lines. For this nonlinear model with binary constraints, we show that all decision variables are separable except for the nonlinear power-flow equations. We develop an iterative decomposition algorithm, which converts the worst-case load shedding problem into a sequence of small subproblems. We show that the subproblems are either convex problems that can be solved efficiently or nonconvex problems that have closed-form solutions. Consequently, our approach is scalable for large networks. Furthermore, we prove the convergence of our algorithm to a critical point, and the objective value is guaranteed to decrease throughout the iterations.

The air blast generated by the explosion of bombs or fuel tankers leads to high-magnitude short-duration loading scenarios that can cause severe structural damage and loss of critical structural members. Hence, more attentions need to put towards bridge structures to develop guidelines to increase the resistance of such structures against the probable blast. Recent advancements in numerical methods have brought about the viable and cost effective facilities to simulate complicated blast scenarios and subsequently provide useful reference for safeguarding design of critical infrastructures. In the previous studies common bridge responses to blast load, the traffic load is sometimes not included in the analysis. Including traffic load will increase the axial compression in bridge piers especially when the axial load is relatively small. Traffic load also can reduce the uplift of girders and deck when the bridge experiences under deck explosion. For more complicated structures like cable-stayed or suspension bridges, however, the effect of traffic loads can be completely different. The tension in the cables increase and progressive collapse is likely to happen while traffic loads exist. Accordingly, this study is an attempt to simulate the effect of traffic load cases on the maximum local and global response of an entire cable-stayed bridge subjected to blast loadings using LS-DYNA explicit finite element code. The blast loads ranged from small to large explosion placed at different positions above the deck. Furthermore, the variation of the traffic load factor in the load combination and its effect on the dynamic response of the bridge under blast load is investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast" title="blast">blast</a>, <a href="https://publications.waset.org/abstracts/search?q=cable-stayed%20bridge" title=" cable-stayed bridge"> cable-stayed bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=LS-DYNA" title=" LS-DYNA"> LS-DYNA</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical" title=" numerical"> numerical</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20load" title=" traffic load"> traffic load</a> </p> <a href="https://publications.waset.org/abstracts/32906/the-effect-of-traffic-load-on-the-maximum-response-of-a-cable-stayed-bridge-under-blast-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32906.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2590</span> Load Forecasting in Short-Term Including Meteorological Variables for Balearic Islands Paper</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Senabre">Carolina Senabre</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Valero"> Sergio Valero</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Lopez"> Miguel Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Gabaldon"> Antonio Gabaldon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a comprehensive survey of the short-term load forecasting (STLF).

The primary goal was to investigate the effects of temperature and geometrical characteristics on the ultimate strength, modes of failure, and initial stiffness of the KK-joints. Results indicated that on an average basis, the ultimate load of a two-planar tubular KK-joint at 200 ºC, 400 ºC, 550 ºC, and 700 ºC is 90%, 75%, 45%, and 16% of the joint’s ultimate load at ambient temperature, respectively. Outcomes of the parametric study showed that replacing the yield stress at ambient temperature with the corresponding value at elevated temperature to apply the EN 1993-1-8 equations for the calculation of the joint’s ultimate load at elevated temperatures may lead to highly unconservative results that might endanger the safety of the structure. Results of the parametric study were then used to develop a set of design formulas, through nonlinear regression analyses, to calculate the ultimate load of two-planar tubular KK-joints subjected to axial loading at elevated temperatures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultimate%20load" title="ultimate load">ultimate load</a>, <a href="https://publications.waset.org/abstracts/search?q=two-planar%20tubular%20KK-joint" title=" two-planar tubular KK-joint"> two-planar tubular KK-joint</a>, <a href="https://publications.waset.org/abstracts/search?q=axial%20loading" title=" axial loading"> axial loading</a>, <a href="https://publications.waset.org/abstracts/search?q=elevated%20temperature" title=" elevated temperature"> elevated temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=parametric%20equation" title=" parametric equation"> parametric equation</a> </p> <a href="https://publications.waset.org/abstracts/108647/numerical-study-on-the-ultimate-load-of-offshore-two-planar-tubular-kk-joints-at-fire-induced-elevated-temperatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108647.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2587</span> Sensitivity Parameter Analysis of Negative Moment Dynamic Load Allowance of Continuous T-Girder Bridge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fan%20Yang">Fan Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ye-Lu%20Wang"> Ye-Lu Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Zhao"> Yang Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The dynamic load allowance, as an application result of the vehicle-bridge coupled vibration theory, is an important parameter for bridge design and evaluation. Based on the coupled vehicle-bridge vibration theory, the current work establishes a full girder model of a dynamic load allowance, selects a planar five-degree-of-freedom three-axis vehicle model, solves the coupled vehicle-bridge dynamic response using the APDL language in the spatial finite element program ANSYS, selects the pivot point 2 sections as the representative of the negative moment section, and analyzes the effects of parameters such as travel speed, unevenness, vehicle frequency, span diameter, span number and forced displacement of the support on the negative moment dynamic load allowance through orthogonal tests. The influence of parameters such as vehicle speed, unevenness, vehicle frequency, span diameter, span number, and forced displacement of the support on the negative moment dynamic load allowance is analyzed by orthogonal tests, and the influence law of each influencing parameter is summarized. It is found that the effects of vehicle frequency, unevenness, and speed on the negative moment dynamic load allowance are significant, among which vehicle frequency has the greatest effect on the negative moment dynamic load allowance; the effects of span number and span diameter on the negative moment dynamic load allowance are relatively small; the effects of forced displacement of the support on the negative moment dynamic load allowance are negligible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continuous%20T-girder%20bridge" title="continuous T-girder bridge">continuous T-girder bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20load%20allowance" title=" dynamic load allowance"> dynamic load allowance</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity%20analysis" title=" sensitivity analysis"> sensitivity analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle-bridge%20coupling" title=" vehicle-bridge coupling"> vehicle-bridge coupling</a> </p> <a href="https://publications.waset.org/abstracts/152547/sensitivity-parameter-analysis-of-negative-moment-dynamic-load-allowance-of-continuous-t-girder-bridge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152547.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2586</span> Settlement Analysis of Axially Loaded Bored Piles: A Case History</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Mert">M.

Strain gauges can be installed into pile in order to determine the shaft resistance of the piles for every soil layer respectively. Detailed results can be obtained by means of strain gauges placed at certain levels into test piles. In the scope of this study, pile load test data obtained from two different projects are examined.  Instrumented static pile load tests were applied on totally 7 test bored piles of different diameters (80 cm, 150 cm, and 200 cm) and different lengths (between 30-76 m) in two different project site. Settlement analysis of test piles is done by using some of load transfer methods and finite element method. Plaxis 3D which is a three-dimensional finite element program is also used for settlement analysis of the test piles. In this study, firstly bearing capacity of test piles are determined and compared with strain gauge data which is required for settlement analysis. Then, settlement values of the test piles are estimated by using load transfer methods developed in recent years and finite element method. The aim of this study is to show similarities and differences between the results obtained from settlement analysis methods and instrumented pile load tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=failure" title="failure">failure</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring%20and%20instrumentation" title=" monitoring and instrumentation"> monitoring and instrumentation</a>, <a href="https://publications.waset.org/abstracts/search?q=pile" title=" pile"> pile</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement" title=" settlement"> settlement</a> </p> <a href="https://publications.waset.org/abstracts/103165/settlement-analysis-of-axially-loaded-bored-piles-a-case-history" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103165.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2585</span> Research on Load Balancing Technology for Web Service Mobile Host</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yao%20Lu">Yao Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiuguo%20Zhang"> Xiuguo Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiying%20Cao"> Zhiying Cao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, Load Balancing idea is used in the Web service mobile host. The main idea of Load Balancing is to establish a one-to-many mapping mechanism: An entrance-mapping request to plurality of processing node in order to realize the dividing and assignment processing. Because the mobile host is a resource constrained environment, there are some Web services which cannot be completed on the mobile host. When the mobile host resource is not enough to complete the request, Load Balancing scheduler will divide the request into a plurality of sub-requests and transfer them to different auxiliary mobile hosts. Auxiliary mobile host executes sub-requests, and then, the results will be returned to the mobile host. Service request integrator receives results of sub-requests from the auxiliary mobile host, and integrates the sub-requests. In the end, the complete request is returned to the client. Experimental results show that this technology adopted in this paper can complete requests and have a higher efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dinic" title="Dinic">Dinic</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20balancing" title=" load balancing"> load balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20host" title=" mobile host"> mobile host</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20service" title=" web service"> web service</a> </p> <a href="https://publications.waset.org/abstracts/63208/research-on-load-balancing-technology-for-web-service-mobile-host" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63208.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">328</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2584</span> Evaluation of Batch Splitting in the Context of Load Scattering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Wesebaum">S.

Willeke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Production companies are faced with an increasingly turbulent business environment, which demands very high production volumes- and delivery date flexibility. If a decoupling by storage stages is not possible (e.g. at a contract manufacturing company) or undesirable from a logistical point of view, load scattering effects the production processes. ‘Load’ characterizes timing and quantity incidence of production orders (e.g. in work content hours) to workstations in the production, which results in specific capacity requirements. Insufficient coordination between load (demand capacity) and capacity supply results in heavy load scattering, which can be described by deviations and uncertainties in the input behavior of a capacity unit. In order to respond to fluctuating loads, companies try to implement consistent and realizable input behavior using the capacity supply available. For example, a uniform and high level of equipment capacity utilization keeps production costs down. In contrast, strong load scattering at workstations leads to performance loss or disproportionately fluctuating WIP, whereby the logistics objectives are affected negatively. Options for reducing load scattering are e.g. shifting the start and end dates of orders, batch splitting and outsourcing of operations or shifting to other workstations. This leads to an adjustment of load to capacity supply, and thus to a reduction of load scattering. If the adaptation of load to capacity cannot be satisfied completely, possibly flexible capacity must be used to ensure that the performance of a workstation does not decrease for a given load. Where the use of flexible capacities normally raises costs, an adjustment of load to capacity supply reduces load scattering and, in consequence, costs. In the literature you mostly find qualitative statements for describing load scattering. Quantitative evaluation methods that describe load mathematically are rare. In this article the authors discuss existing approaches for calculating load scattering and their various disadvantages such as lack of opportunity for normalization. These approaches are the basis for the development of our mathematical quantification approach for describing load scattering that compensates the disadvantages of the current quantification approaches. After presenting our mathematical quantification approach, the method of batch splitting will be described. Batch splitting allows the adaptation of load to capacity to reduce load scattering. After describing the method, it will be explicitly analyzed in the context of the logistic curve theory by Nyhuis using the stretch factor α1 in order to evaluate the impact of the method of batch splitting on load scattering and on logistic curves. The conclusion of this article will be to show how the methods and approaches presented can help companies in a turbulent environment to quantify the occurring work load scattering accurately and apply an efficient method for adjusting work load to capacity supply. In this way, the achievements of the logistical objectives are increased without causing additional costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=batch%20splitting" title="batch splitting">batch splitting</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20logistics" title=" production logistics"> production logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20planning%20and%20control" title=" production planning and control"> production planning and control</a>, <a href="https://publications.waset.org/abstracts/search?q=quantification" title=" quantification"> quantification</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20scattering" title=" load scattering"> load scattering</a> </p> <a href="https://publications.waset.org/abstracts/36923/evaluation-of-batch-splitting-in-the-context-of-load-scattering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36923.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">399</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2583</span> Short-Term Load Forecasting Based on Variational Mode Decomposition and Least Square Support Vector Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiangyong%20Liu">Jiangyong Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiangxiang%20Xu"> Xiangxiang Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Bote%20Luo"> Bote Luo</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoxue%20Luo"> Xiaoxue Luo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiang%20Zhu"> Jiang Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lingzhi%20Yi"> Lingzhi Yi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To address the problems of non-linearity and high randomness of the original power load sequence causing the degradation of power load forecasting accuracy, a short-term load forecasting method is proposed. The method is based on the Least Square Support Vector Machine optimized by an Improved Sparrow Search Algorithm combined with the Variational Mode Decomposition proposed in this paper. The application of the variational mode decomposition technique decomposes the raw power load data into a series of Intrinsic Mode Functions components, which can reduce the complexity and instability of the raw data while overcoming modal confounding; the proposed improved sparrow search algorithm can solve the problem of difficult selection of learning parameters in the least Square Support Vector Machine.

For some piezoelectric actuator applications, arbitrary voltage is required to actuate. Especially for unidirectional arbitrary voltage driving like as sine wave, some special inverter with circuit that can charge and discharge the capacitive energy can be used. In this case, the difference between power supply level and the object voltage level for RC load is varied. Because the control gain is constant, the controlled output is not uniform according to the voltage difference. In this paper, for charge and discharge circuit for unidirectional arbitrary voltage driving for piezoelectric actuator, the controller gain is controlled according to the voltage difference. With the proposed simple idea, the load voltage can have controlled smoothly although the voltage difference is varied. The appropriateness is proved from the simulation of the proposed circuit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analog%20voltage%20inverter" title="analog voltage inverter">analog voltage inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=capacitive%20load" title=" capacitive load"> capacitive load</a>, <a href="https://publications.waset.org/abstracts/search?q=gain%20control" title=" gain control"> gain control</a>, <a href="https://publications.waset.org/abstracts/search?q=dc-dc%20converter" title=" dc-dc converter"> dc-dc converter</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectric" title=" piezoelectric"> piezoelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20waveform" title=" voltage waveform"> voltage waveform</a> </p> <a href="https://publications.waset.org/abstracts/34752/analog-voltage-inverter-drive-for-capacitive-load-with-adaptive-gain-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34752.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">655</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2581</span> Load-Settlement Behaviour of Geogrid-Reinforced Sand Bed over Granular Piles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sateesh%20Kumar%20Pisini">Sateesh Kumar Pisini</a>, <a href="https://publications.waset.org/abstracts/search?q=Swetha%20Priya%20Darshini%20Thammadi"> Swetha Priya Darshini Thammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar%20Shukla"> Sanjay Kumar Shukla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Granular piles are a popular ground improvement technique in soft cohesive soils as well as for loose non-cohesive soils. The present experimental study has been carried out on granular piles in loose (Relative density = 30%) and medium dense (Relative density = 60%) sands with geogrid reinforcement within the sand bed over the granular piles. A group of five piles were installed in the sand at different spacing, s = 2d, 3d and 4d, d being the diameter of the pile. The length (L = 0.4 m) and diameter (d = 50 mm) of the piles were kept constant for all the series of experiments. The load-settlement behavior of reinforced sand bed and granular piles system was studied by applying the load on a square footing. The results show that the effect of reinforcement increases the load bearing capacity of the piles. It is also found that an increase in spacing between piles decreases the settlement for both loose and medium dense soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=granular%20pile" title="granular pile">granular pile</a>, <a href="https://publications.waset.org/abstracts/search?q=load-carrying%20capacity" title=" load-carrying capacity"> load-carrying capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement" title=" settlement"> settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=geogrid%20reinforcement" title=" geogrid reinforcement"> geogrid reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=sand" title=" sand"> sand</a> </p> <a href="https://publications.waset.org/abstracts/95179/load-settlement-behaviour-of-geogrid-reinforced-sand-bed-over-granular-piles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95179.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">391</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2580</span> Finite Element Analysis of Debonding Propagation in FM73 Joint under Static Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Hedayati">Reza Hedayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Jahanbakhshi"> Meysam Jahanbakhshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, Fracture Mechanics is used to predict crack propagation in the adhesive joining aluminum and composite plates.

Their ability to recover large displacements has been used in many applications, including structural stability/response enhancement and active structural acoustic control. SMA wires or fibers can be embedded with composite cylinders to increase their critical buckling load, improve their load-deflection behavior, and reduce the radial deflections under various thermo-mechanical loadings. This paper presents a semi-analytical investigation on the non-linear load-deflection response of SMA-reinforced composite circular cylindrical shells. The cylinder shells are under uniform external pressure load. Based on first-order shear deformation<em> shell theory (FSDT),</em> the equilibrium equations of the structure are derived. One-dimensional simplified Brinson’s model is used for determining the SMA recovery force due to its simplicity and accuracy. Airy stress function and Galerkin technique are used to obtain non-linear load-deflection curves. The results are verified by comparing them with those in the literature. Several parametric studies are conducted in order to investigate the effect of SMA volume fraction, SMA pre-strain value, and SMA activation temperature on the response of the structure. It is shown that suitable usage of SMA wires results in a considerable enhancement in the load-deflection response of the shell due to the generation of the SMA tensile recovery force. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airy%20stress%20function" title="airy stress function">airy stress function</a>, <a href="https://publications.waset.org/abstracts/search?q=cylindrical%20shell" title=" cylindrical shell"> cylindrical shell</a>, <a href="https://publications.waset.org/abstracts/search?q=Galerkin%20technique" title=" Galerkin technique"> Galerkin technique</a>, <a href="https://publications.waset.org/abstracts/search?q=load-deflection%20curve" title=" load-deflection curve"> load-deflection curve</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery%20stress" title=" recovery stress"> recovery stress</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20memory%20alloy" title=" shape memory alloy"> shape memory alloy</a> </p> <a href="https://publications.waset.org/abstracts/96718/non-linear-load-deflection-response-of-shape-memory-alloys-reinforced-composite-cylindrical-shells-under-uniform-radial-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96718.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2577</span> The Intensity of Load Experienced by Female Basketball Players during Competitive Games</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Vencurik">Tomas Vencurik</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiri%20Nykodym"> Jiri Nykodym</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study compares the intensity of game load among player positions and between the 1st and the 2nd half of the games. Two guards, three forwards, and three centers (female basketball players) participated in this study. The heart rate (HR) and its development were monitored during two competitive games. Statistically insignificant differences in the intensity of game load were recorded between guards, forwards, and centers below and above 85% of the maximal heart rate (HRmax) and in the mean HR as % of HRmax (87.81±3.79%, 87.02±4.37%, and 88.76±3.54%, respectively). Moreover, when the 1st and the 2nd half of the games were compared in the mean HR (87.89±4.18% vs. 88.14±3.63% of HRmax), no statistical significance was recorded. This information can be useful for coaching staff, to manage and to precisely plan the training process. <p class="card-text"><strong>Keywords:</strong> <a
