Tests to failure on six half-scale specimens were conducted for slab-interior column connections transferring shear force and unbalanced moment. The influences on connection ductility of four parameters; namely, the moment to shear force ratio, the ratio of column side length to slab effective depth, the aspect ratio of the column cross section, and the presence of four square openings located next to column corners were investigated. The study revealed marked effects of these parameters on connection ductility. Increasing the first and second parameters, were found to be in favor of increasing connection ductility, while the third and fourth parameters were found to have negative effects on the connection ductility. These findings should, hopefully, help in designing interior connections of flat slab structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ductility" title="ductility">ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=flat%20slab" title=" flat slab"> flat slab</a>, <a href="https://publications.waset.org/abstracts/search?q=failure" title=" failure"> failure</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20force" title=" shear force"> shear force</a>, <a href="https://publications.waset.org/abstracts/search?q=moment" title=" moment"> moment</a>, <a href="https://publications.waset.org/abstracts/search?q=unbalanced%20moment" title=" unbalanced moment"> unbalanced moment</a>, <a href="https://publications.waset.org/abstracts/search?q=punching%20failure" title=" punching failure"> punching failure</a>, <a href="https://publications.waset.org/abstracts/search?q=connection" title=" connection"> connection</a>, <a href="https://publications.waset.org/abstracts/search?q=interior-column%20connection" title=" interior-column connection"> interior-column connection</a> </p> <a href="https://publications.waset.org/abstracts/8917/ductility-of-slab-interior-column-connections-transferring-shear-and-moment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8917.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">404</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">4839</span> Influence of Slenderness Ratio on the Ductility of Reinforced Concrete Portal Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kahil%20Amar">Kahil Amar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nekmouche%20Aghiles"> Nekmouche Aghiles</a>, <a href="https://publications.waset.org/abstracts/search?q=Titouche%20Billal"> Titouche Billal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamizi%20Mohand"> Hamizi Mohand</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannachi%20Naceur%20Eddine"> Hannachi Naceur Eddine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ductility is an important parameter in the nonlinear behavior of portal structures reinforced concrete.

Nineteen normal strength concrete rectangular columns with different variables tested in this research were used to study the effect of concrete compressive strength and rectangularity ratio on strength and ductility of columns. The paper also presents a nonlinear finite element analysis for these specimens and another twenty high strength concrete square columns tested by other researchers using ANSYS 15 finite element software. The results indicate that the axial force – axial strain relationship obtained from the analytical model using ANSYS are in good agreement with the experimental data. The comparison shows that the ANSYS is capable of modeling and predicting the actual nonlinear behavior of confined normal and high-strength concrete columns under concentric loading. The maximum applied load and the maximum strain have also been confirmed to be satisfactory. Depending on this agreement between the experimental and analytical results, a parametric numerical study was conducted by ANSYS 15 to clarify and evaluate the effect of each variable on strength and ductility of the columns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANSYS" title="ANSYS">ANSYS</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20compressive%20strength%20effect" title=" concrete compressive strength effect"> concrete compressive strength effect</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility" title=" ductility"> ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=rectangularity%20ratio" title=" rectangularity ratio"> rectangularity ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/51557/effect-of-concrete-strength-and-aspect-ratio-on-strength-and-ductility-of-concrete-columns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51557.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">513</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">4836</span> The Overload Behaviour of Reinforced Concrete Flexural Members</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angelo%20Thurairajah">Angelo Thurairajah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sufficient ultimate deformation is necessary to demonstrate the member ductility, which is dependent on the section and the material ductility. The concrete cracking phase of softening prior to the plastic hinge formation is an essential feature as well. The nature of the overload behaviour is studied using the order of the ultimate deflection. The ultimate deflection is primarily dependent on the slenderness (span to depth ratio), the ductility of the reinforcing steel, the degree of moment redistribution, the type of loading, and the support conditions. The ultimate deflection and the degree of moment redistribution from the analytical study are in good agreement with the experimental results and the moment redistribution provisions of the Australian Standards AS3600 Concrete Structures Code. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ductility" title="ductility">ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=softening" title=" softening"> softening</a>, <a href="https://publications.waset.org/abstracts/search?q=ultimate%20deflection" title=" ultimate deflection"> ultimate deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=overload%20behaviour" title=" overload behaviour"> overload behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20redistribution" title=" moment redistribution"> moment redistribution</a> </p> <a href="https://publications.waset.org/abstracts/140709/the-overload-behaviour-of-reinforced-concrete-flexural-members" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140709.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">88</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">4835</span> Ductility Reduction Factors for Displacement Spectra Corresponding to Soft Soil Zone of the Valley of Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=No%C3%A9%20D.%20Lazos-Gallardo">Noé D.

The aim is to allow a better characterization of the displacement spectra and provide a simple expression to be used in displacement based design (DBD). Emphasis is on the Mexico City Building Code. The study is based on the analysis of single degree of freedom (SDOF) systems with elasto-plastic hysteretic behavior. Several seismic ground motions corresponding to subduction events with magnitudes equal to or greater than 6 and recorded in different stations of Mexico City are used. The proposed expression involves the ratio of elastic and inelastic pseudo-aceleration spectra, and depends on factors such the ductility demand and the vibration period of the structural system. The resulting ductility reduction factors obtained in this study are compared with others existing in the literature, and their advantages and disadvantages are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=displacement%20based%20design" title="displacement based design">displacement based design</a>, <a href="https://publications.waset.org/abstracts/search?q=displacements%20spectrum" title=" displacements spectrum"> displacements spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility%20reduction%20factors" title=" ductility reduction factors"> ductility reduction factors</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20soil" title=" soft soil"> soft soil</a> </p> <a href="https://publications.waset.org/abstracts/83199/ductility-reduction-factors-for-displacement-spectra-corresponding-to-soft-soil-zone-of-the-valley-of-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83199.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">179</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">4834</span> Seismic Retrofit of Rectangular Columns Using Fiber Reinforced Polymers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20L.%20Elghazy">E.

Designing FRP confined concrete columns requires reliable analytical tools that predict the level of performance and ductility enhancement. A numerical procedure is developed aiming at determining the type and thickness of FRP jacket needed to achieve a certain level of ductility enhancement. The procedure starts with defining the stress strain curve, which is used to obtain moment curvature relationship then displacement ductility ratio of reinforced concrete cross-sections subjected to bending moment and axial force. Three sets of published experimental tests were used to validate the numerical procedure. Comparisons between predicted results obtained by using the proposed procedure and actual results of experimental tests proved the reliability of the proposed procedure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=columns" title="columns">columns</a>, <a href="https://publications.waset.org/abstracts/search?q=confinement" title=" confinement"> confinement</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility" title=" ductility"> ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=FRP" title=" FRP"> FRP</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical" title=" numerical"> numerical</a> </p> <a href="https://publications.waset.org/abstracts/16993/seismic-retrofit-of-rectangular-columns-using-fiber-reinforced-polymers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16993.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">455</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">4833</span> Experimental Studies on Prestressed Precast Concrete Bridge Piers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Shim">C.

Design requirements on minimum transverse reinforcement ratio are not included in current design codes. Pre stressing introduces additional compression to the column. Precast columns with different transverse reinforcement ratios were tested to derive adequate design requirement. Displacement ductility of the pre stressed precast columns was evaluated and compared with previous studies. Design of axial steels including reinforcing bars and pre stressing tendons influenced on the seismic performance. Without significant increase of transverse reinforcement ratio, the specimens showed required displacement ductility without reduction of their flexural strength.

The parameters studied are the steel fibre contents, the aspect ratio of fibres and the concrete strength. Prismatic specimens of dimensions 10x10x35cm made of concrete of various yield stress reinforced with steel fibres hooked at the ends with three fibre volume fractions (i.e. 0, 0.5, and 1%) and two aspects ratio (65 and 80) were tested to direct shear. Three types of concretes with various compressive strength and yield stress were tested, an ordinary concrete (OC), a self-compacting concrete (SCC) and a high strength concrete (HSC). The concrete strengths investigated include 30 MPa for OC, 60 MPa for SCC and 80 MPa for HSC. The results show that the shear strength and ductility are affected and have been improved very significantly by the fibre contents, fibre aspect ratio and concrete strength. As the compressive strength and the volume fraction of fibres increase, the shear strength increases. However, yield stress of concrete has an important influence on the orientation and distribution of the fibres in the matrix. The ductility was much higher for ordinary and self-compacting concretes (concrete with good workability). The ductility in direct shear depends on the fibre orientation and is significantly improved when the fibres are perpendicular to the shear plane. On the contrary, for concrete with poor workability, an inadequate distribution and orientation of fibres occurred, leading to a weak contribution of the fibres to the direct shear behaviour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete" title="concrete">concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=fibre" title=" fibre"> fibre</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20shear" title=" direct shear"> direct shear</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20stress" title=" yield stress"> yield stress</a>, <a href="https://publications.waset.org/abstracts/search?q=orientation" title=" orientation"> orientation</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/22002/influence-of-yield-stress-and-compressive-strength-on-direct-shear-behaviour-of-steel-fibre-reinforced-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22002.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">547</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">4830</span> Investigation of Steel Infill Panels under Blast Impulsive Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20M.%20Zahrai">Seyed M.

However, magnesium alloys are still restricted in engineering applications because of their lower strength and ductility. Hence, there are large spaces and challenges in achieving high-performance Mg alloys. This work reports an Mg-Gd-Er-Zn-Zr alloy with ultrahigh strength and good ductility developed via hot extrusion, pre-deformation, and two-stage aging. The extruded alloy comprises fine dynamically recrystallized (DRXed) grains and coarse worked grains with a large aspect ratio. Pre-deformation has little effect on the microstructure and macro-texture and serves primarily to introduce a large number of dislocations, resulting in strain hardening and higher precipitation strengthening during subsequent aging due to more nucleation sites. As a result, the alloy exhibits a yield strength (YS) of 506 MPa, an ultimate tensile strength (UTS) of 549 MPa, and elongation (EL) of 8.2% at room temperature, showing superior strength-ductility balance than the other wrought Mg-RE alloys previously reported. The current study proposes a combination of pre-deformation and two-stage aging to further improve the mechanical properties of wrought Mg alloys for engineering applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnesium%20alloys" title="magnesium alloys">magnesium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-deformation" title=" pre-deformation"> pre-deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=two-stage%20aging" title=" two-stage aging"> two-stage aging</a> </p> <a href="https://publications.waset.org/abstracts/123503/development-of-a-mg-gd-er-zn-zr-alloy-with-ultrahigh-strength-and-ductility-via-extrusion-pre-deformation-and-two-stage-aging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123503.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">173</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">4828</span> Ductility Spectrum Method for the Design and Verification of Structures </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Chikh">B.

The approach considers the effect of two orthogonal components of the ground motions as well as the influence of soil-structure interaction. The approach involves the calculation of ductility demand hazard curves for symmetric systems and, alternatively, for systems with different degrees of asymmetry. To get this objective, demand hazard curves corresponding to different global ductility demands of the systems are calculated. Next, Uniform Exceedance Rate Spectra (UERS) are developed for a specific mean annual rate of exceedance value. Ratios between UERS corresponding to asymmetric and to symmetric systems located in soft soil of the valley of Mexico are obtained. Results indicate that the ductility demands corresponding to tilted structures may be several times higher than those corresponding to symmetric structures, depending on several factors such as tilting angle and vibration period of structure and soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20yielding" title="asymmetric yielding">asymmetric yielding</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title=" seismic performance"> seismic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20reliability" title=" structural reliability"> structural reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=tilted%20structures" title=" tilted structures"> tilted structures</a> </p> <a href="https://publications.waset.org/abstracts/22149/reliability-based-ductility-seismic-spectra-of-structures-with-tilting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22149.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">514</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">4826</span> Seismic Performance of Micropiles in Sand with Predrilled Oversized Holes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cui%20Fu">Cui Fu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Zhou%20Zhuang"> Yi-Zhou Zhuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheng-Zhi%20Wang"> Sheng-Zhi Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Full scale tests of six micropiles with different predrilled-hole parameters under low frequency cyclic lateral loading in-sand were carried out using the MTS hydraulic loading system to analyze the seismic performance of micropiles.

The experimental results show the hysteresis curves appear like plump bows in the elastic–plastic stage and failure stage which exhibit good hysteretic characteristics without pinching phenomena and good energy dissipating capacities. The ductility coefficient varies from 2.51 to 3.54 and the depth and loose backfill of oversized holes can improve ductility, but the diameter of predrilled-hole has a limited effect on enhancing its ductility.

However, the ductility of the AM alloy was significantly less than the wrought alloy. The ductility however was recovered with hot isostatic pressing (HIP) of the AM specimens.

Against these preferable characteristics, magnesium is difficult to deform at room temperature therefore it is alloyed with other elements mainly Aluminum and Zinc to add some required properties particularly for their high strength - to -weight ratio. Mg and its alloys oxidize rapidly therefore care should be taken during melting or machining them; but they are not fire hazardous. Grain refinement is an important technology to improve the mechanical properties and the micro structure uniformity of the alloys. Grain refinement has been introduced in early fifties; when Cibula showed that the presence of Ti, and Ti+ B, produced a great refining effect in Al. since then it became an industrial practice to grain refine Al. Most of the published work on grain refinement was directed toward grain refining Al and Zinc alloys; however, the effect of the addition of rare earth material on the grain size or the mechanical behavior of Mg alloys has not been previously investigated. This forms the main objective of the research work; where, the effect of Ti addition on the grain size, mechanical behavior, ductility, and the extrusion force & energy consumed in forward extrusion of Mg-AZ31 alloy is investigated and discussed in two conditions, first in the as cast condition and the second after extrusion. It was found that addition of Ti to Mg- AZ31 alloy has resulted in reduction of its grain size by 14%; the reduction in grain size after extrusion was much higher. However the increase in Vicker’s hardness was 3% after the addition of Ti in the as cast condition, and higher values for Vicker’s hardness were achieved after extrusion. Furthermore, an increase in the strength coefficient by 36% was achieved with the addition of Ti to Mg-AZ31 alloy in the as cast condition. Similarly, the work hardening index was also increased indicating an enhancement of the ductility and formability. As for the extrusion process, it was found that the force and energy required for the extrusion were both reduced by 57% and 59% with the addition of Ti. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cast%20condition" title="cast condition">cast condition</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20extrusion" title=" direct extrusion"> direct extrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility" title=" ductility"> ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=MgAZ31%20alloy" title=" MgAZ31 alloy"> MgAZ31 alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=super%20-%20plasticity" title=" super - plasticity"> super - plasticity</a> </p> <a href="https://publications.waset.org/abstracts/32854/investigation-on-the-effect-of-titanium-ti-plus-boron-b-addition-to-the-mg-az31-alloy-in-the-as-cast-and-after-extrusion-on-its-metallurgical-and-mechanical-characteristics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32854.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">456</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">4820</span> Experimental Study on Single Bay RC Frame Designed Using EC8 under In-Plane Cyclic Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20H.%20Hamid">N.

Moment resisting RC frame was designed using EC8 by including the provision for seismic loading and detailing of its connection. The objective of the experimental work is to determine seismic behaviour RC frame under in-plane lateral cyclic loading using displacement control method. A double actuator is placed at centre of the mass concrete block at top of frame to represent the seismic load. The percentage drifts are starting from ±0.01% until ±2.25% with increment of ±0.25% drift. The ultimate lateral load of 158.48 kN was recorded at +2.25% drift in pushing and -126.09 kN in pulling direction. From the experimental hysteresis loops, the parameters such as lateral strength capacity, stiffness, ductility and equivalent viscous damping can be obtained. RC frame behaves in the elastic manner followed by inelastic behaviour after reaches the yield limit. The ductility value for this type frame is 4 which lies between the limit 3 and 6. Therefore, it is recommended to build this RC frame for moderate seismic regions under Ductility Class Medium (DCM) such as in Sabah, East Malaysia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=single%20bay" title="single bay">single bay</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20resisting%20RC%20frame" title=" moment resisting RC frame"> moment resisting RC frame</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility%20class%20medium" title=" ductility class medium"> ductility class medium</a>, <a href="https://publications.waset.org/abstracts/search?q=inelastic%20behavior" title=" inelastic behavior"> inelastic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20load" title=" seismic load"> seismic load</a> </p> <a href="https://publications.waset.org/abstracts/36154/experimental-study-on-single-bay-rc-frame-designed-using-ec8-under-in-plane-cyclic-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36154.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">392</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">4819</span> Modified Side Plate Design to Suppress Lateral Torsional Buckling of H-Beam for Seismic Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erwin">Erwin</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng-Cheng%20Chen"> Cheng-Cheng Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20J.%20Salim"> Charles J.

Some modifications in designing the side plates are made in this study to simplify the construction in the field and reduce the cost. At certain region, side plates are not added: (1) At the beam end to preserve some spaces for bolt installation, but the beam is strengthened by adding cover plate at both flanges and (2) at the middle span of the beam where the moment is smaller. Three small scale full span beam specimens are tested under cyclic loading to investigate the LTB resistant and the ductility of the proposed design method. Test results show that the LTB deformation can be effectively suppressed and very high ductility level can be achieved. Following the test, a finite element analysis (FEA) model is established and is verified using the test results. An intensive parametric study is conducted using the established FEA model. The analysis reveals that the length of side plates is the most important parameter determining the performance of the beam and the required side plates length is determined by some parameters which are (1) beam depth to flange width ratio, (2) beam slenderness ratio (3) strength and thickness of the side plates, (4) compactness of beam web and flange, and (5) beam yield strength. At the end of the paper, a design formula to calculate the required side plate length is suggested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cover%20plate" title="cover plate">cover plate</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake%20resistant%20design" title=" earthquake resistant design"> earthquake resistant design</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20torsional%20buckling" title=" lateral torsional buckling"> lateral torsional buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=side%20plate" title=" side plate"> side plate</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20structure" title=" steel structure"> steel structure</a> </p> <a href="https://publications.waset.org/abstracts/96206/modified-side-plate-design-to-suppress-lateral-torsional-buckling-of-h-beam-for-seismic-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96206.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">180</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">4818</span> Behavior of Oil Palm Shell Reinforced Concrete Beams Added with Kenaf Fibres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharifah%20M.%20Syed%20Mohsin">Sharifah M.

The work aim is to examine the potential of using kenaf fibres to improve the strength and ductility of the OPSRC beams and also observe its potential in serving as part of shear reinforcement in the beams. Two different arrangements of the shear links in OPSRC beams with a selection of kenaf fibres (amount of [10kg/m] ^3 and [20kg/m] ^3) content are tested under monotonic loading. In the first arrangement, the kenaf fibres are added to the beam which has full shear reinforcement to study the structural behavior of OPSRC beams with fibres. In the second arrangement, the spacing between the shear links in the OPSRC beams are increased by 50% and experimental work is carried out to study the effect of kenaf fibres without compromising the beams strength and ductility. The results show that the addition of kenaf fibres enhanced the load carrying capacity, ductility and also altered the failure mode of the beams from a brittle shear mode to a flexural ductile one. Furthermore, the study depicts that kenaf fibres are compatible with OPSRC and suggest prospective results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oil%20palm%20shell%20reinforced%20concrete" title="oil palm shell reinforced concrete">oil palm shell reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=kenaf%20fibres" title=" kenaf fibres"> kenaf fibres</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20strength" title=" peak strength"> peak strength</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility" title=" ductility"> ductility</a> </p> <a href="https://publications.waset.org/abstracts/5706/behavior-of-oil-palm-shell-reinforced-concrete-beams-added-with-kenaf-fibres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5706.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">4817</span> Response Reduction Factor for Earthquake Resistant Design of Special Moment Resisting Frames</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rohan%20V.%20Ambekar">Rohan V.

Calculation of response reduction factor (R) is done as per the new formulation of response reduction factor (R) given by Applied Technology Council (ATC)-19 which is the product of strength factor (Rs), ductility factor (Rµ) and redundancy factor (RR). The analysis revealed that these three factors affect the actual value of response reduction factor (R) and therefore they must be taken into consideration while determining the appropriate response reduction factor to be used during the seismic design process. The actual values required for determination of response reduction factor (R) is worked out on the basis of pushover curve which is a plot of base shear verses roof displacement. Finally, the calculated values of response reduction factor (R) of reinforced concrete special moment resisting frame (SMRF) with and without shear wall are compared with the codal values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=response%20reduction%20factor" title="response reduction factor">response reduction factor</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility%20ratio" title=" ductility ratio"> ductility ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20shear" title=" base shear"> base shear</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20moment%20resisting%20frames" title=" special moment resisting frames"> special moment resisting frames</a> </p> <a href="https://publications.waset.org/abstracts/1362/response-reduction-factor-for-earthquake-resistant-design-of-special-moment-resisting-frames" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1362.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">496</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">4816</span> Increase the Ductility of Tall Buildings Using Green Material Bamboo for Earthquake Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shef%20Amir%20Arasy">Shef Amir Arasy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In 2023, the world's population will be 7.8 billion, which has increased significantly in the last 20 years. Every country in the world is experiencing the impacts of climate change directly and indirectly. However, the community still needs to build massive infrastructure and buildings. The massive CO2 emissions which lead to climate change come from cement usage in construction activity. Bamboo is one of the most sustainable materials for reducing carbon emissions and releasing more than 30% oxygen compared to the mass of trees. Besides, bamboo harvest time is faster than other sustainable materials, around 3-4 years. Furthermore, Bamboo has a high tensile strength, which can provide ductility effectively to prevent damage to buildings during an earthquake. By the finite element method, this research analyzes bamboo configuration and connection for tall building structures under different earthquake frequencies and fire. The aim of this research is to provide proper design and connection of bamboo buildings that can be more reliable than concrete structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bamboo" title="bamboo">bamboo</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility" title=" ductility"> ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake." title=" earthquake."> earthquake.</a> </p> <a href="https://publications.waset.org/abstracts/162511/increase-the-ductility-of-tall-buildings-using-green-material-bamboo-for-earthquake-zone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162511.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">76</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">4815</span> Seismic Performance of Various Grades of Steel Columns through Finite Element Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asal%20Pournaghshband">Asal Pournaghshband</a>, <a href="https://publications.waset.org/abstracts/search?q=Roham%20Maher"> Roham Maher</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a numerical analysis of the cyclic behavior of H-shaped steel columns, focusing on different steel grades, including austenitic, ferritic, duplex stainless steel, and carbon steel. Finite Element (FE) models were developed and validated against experimental data, demonstrating a predictive accuracy of up to 6.5%. The study examined key parameters such as energy dissipation and failure modes. Results indicate that duplex stainless steel offers the highest strength, with superior energy dissipation but a tendency for brittle failure at maximum strains of 0.149. Austenitic stainless steel demonstrated balanced performance with excellent ductility and energy dissipation, showing a maximum strain of 0.122, making it highly suitable for seismic applications. Ferritic stainless steel, while stronger than carbon steel, exhibited reduced ductility and energy absorption. Carbon steel displayed the lowest performance in terms of energy dissipation and ductility, with significant strain concentrations leading to earlier failure. These findings provide critical insights into optimizing material selection for earthquake-resistant structures, balancing strength, ductility, and energy dissipation under seismic conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20dissipation" title="energy dissipation">energy dissipation</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=H-shaped%20columns" title=" H-shaped columns"> H-shaped columns</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title=" seismic performance"> seismic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=stainless%20steel%20grades" title=" stainless steel grades"> stainless steel grades</a> </p> <a href="https://publications.waset.org/abstracts/191066/seismic-performance-of-various-grades-of-steel-columns-through-finite-element-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191066.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">43</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">4814</span> Ultimate Stress of the Steel Tube in Circular Concrete-Filled Steel Tube Stub Columns Subjected to Axial Compression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siqi%20Lin">Siqi Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yangang%20Zhao"> Yangang Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concrete-filled steel tube column achieves the excellent performance of high strength, stiffness, and ductility due to the confinement from the steel tube.

Experimental tests were conducted to investigate the effects of the parameters, including concrete strength, steel strength, and D/t ratio, on the ultimate stress of the steel tube. The stress of the steel tube was determined by employing the Prandtl-Reuss flow rule associated with isotropic strain hardening.

We develop a full analytical procedure that provides the ductility demand as a function of these six dimensionless parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20procedure" title="analytical procedure">analytical procedure</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20loading" title=" blast loading"> blast loading</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20force" title=" membrane force"> membrane force</a>, <a href="https://publications.waset.org/abstracts/search?q=P-I%20diagram" title=" P-I diagram"> P-I diagram</a> </p> <a href="https://publications.waset.org/abstracts/13731/full-analytical-procedure-to-derive-p-i-diagram-of-a-steel-beam-under-blast-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13731.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">433</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">4812</span> Effect of Site Amplification on Seismic Safety Evaluation of Flyover Pier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Raihan%20Mukhlis">Mohammad Raihan Mukhlis</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Abdur%20Rahman%20Bhuiyan"> M.

Being situated in a seismically active region, seismic safety evaluation of flyovers is essential for seismic risk reduction. Effects of site amplification on seismic safety evaluation of flyover piers are the main concern of this study. In this regard, failure mode, lateral strength and displacement ductility of piers of a typical multi-span simply supported flyover have been evaluated by Japan Road Association (JRA) recommended guidelines, with and without considering site amplification. Ultimate flexural strengths of piers have been computed using the pushover analysis results. Shear capacity of piers has been calculated using the guidelines of JRA. Lateral strengths have been determined depending on the failure modes of the piers. Displacement ductility of piers has been computed using yield and ultimate displacements of the piers obtained from the pushover analysis results. Selected earthquake time history is used in seismic safety evaluation of the flyover piers. Finally, the ductility design method is used to conduct the seismic safety evaluation of the piers with and without considering site amplification. From the numerical results, it has been revealed that the effects of site amplification on seismic safety evaluation of bridge structures should be carefully taken into account. <p
