With the failure of bridges that under operating conditions lead to focus on updating the default bridge inspection methodology. The structures health monitoring (SHM) using the vibration response appeared as a promising method to evaluate the condition of structures. The rapid development in the sensors technology and the condition assessment techniques based on the vibration-based damage detection made the SHM an efficient and economical ways to assess the bridges. SHM is set to assess state and expects probable failures of designated bridges.

Due to the fewer applied materials and offering a higher structural efficiency compared to solid concrete beams with the same concrete area, hollow reinforced concrete beams (HRCB) internally reinforced with steel rebars have been employed extensively for bridge structural members and high-rise buildings. Many experimental studies have been conducted to investigate the behavior of hollow beams subjected to bending loading and found that the structural performance of HRCBs is critically affected by many design parameters. While the proper design of the HRCBs demonstrated comparable behavior to solid sections, inappropriate design leads beams to be extremely prone to brittle failure. Another potential issue that needs to be further investigated is the replacement of steel bars with suitable materials due to their susceptibility to corrosion. Hence, to develop a reliable construction system, the application of GFRP bars as a non-corroding material has been utilized. Furthermore, this study aims to critically review the different design parameters that affect the flexural performance of the HRCBs and recognize the gaps of knowledge in the better design and more effective use of this construction system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20parameters" title="design parameters">design parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20investigations" title=" experimental investigations"> experimental investigations</a>, <a href="https://publications.waset.org/abstracts/search?q=hollow%20reinforced%20concrete%20beams" title=" hollow reinforced concrete beams"> hollow reinforced concrete beams</a>, <a href="https://publications.waset.org/abstracts/search?q=steel" title=" steel"> steel</a>, <a href="https://publications.waset.org/abstracts/search?q=GFRP" title=" GFRP"> GFRP</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength" title=" flexural strength"> flexural strength</a> </p> <a href="https://publications.waset.org/abstracts/151020/review-of-affected-parameters-on-flexural-behavior-of-hollow-concrete-beams-reinforced-by-steelgfrp-rebars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151020.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">202</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">2415</span> Willingness to Adopt "Green Steel" Products: A Case Study from the Automotive Sector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Muslemani">Hasan Muslemani</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Wilson"> Jeffrey Wilson</a>, <a href="https://publications.waset.org/abstracts/search?q=Xi%20Liang"> Xi Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Ascui"> Francisco Ascui</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Kaesehage"> Katharina Kaesehage</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to examine consumer behaviour towards, and the willingness to adopt, green steel use in the automotive sector, in order to identify potential barriers and opportunities for its widespread adoption. Semi-structured interviews were held with experts from global, regional and country-specific industry associations and automakers. The analysis shows there is a new shift towards lifecycle thinking in the sector, although these efforts have been voluntary and driven by customer and employee pressures rather than regulation. The paper further appraises possible demand for green steel within different vehicle types (based on size and powertrain), and shows that manufacturers of electric heavy-duty vehicles are most likely to adopt green steel in the first instance, given the amount of incorporated steel in the vehicles and the fact that lifecycle emissions lie predominantly in their manufacturing phase. A case for green advanced higher-strength steels (AHSS) can also be made in light-duty passenger vehicles, which may mitigate competition from light-weight alternative materials in terms of cost and greenness (depending on source and utilisation zones). This work builds on a wide sustainability-related literature in the automotive sector and highlights areas in need of urgent action if the sector as a whole were to meet its Paris Agreement climate targets, in particular a need to revisit current CO2 performance regulations to include Scope 1 and Scope 2 emissions, engage in educational green marketing campaigns, and explore innovative market-based mechanisms to bridge the gap between relatively-low carbon abatement costs of steelmaking and high abatement costs of vehicle manufacturing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Green%20steel" title="Green steel">Green steel</a>, <a href="https://publications.waset.org/abstracts/search?q=Consumer%20behaviour" title=" Consumer behaviour"> Consumer behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=Automotive%20industry" title=" Automotive industry"> Automotive industry</a>, <a href="https://publications.waset.org/abstracts/search?q=Environmental%20sustainability" title=" Environmental sustainability"> Environmental sustainability</a> </p> <a href="https://publications.waset.org/abstracts/133156/willingness-to-adopt-green-steel-products-a-case-study-from-the-automotive-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133156.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">164</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">2414</span> Study of Ultrasonic Waves in Unidirectional Fiber-Reinforced Composite Plates for the Aerospace Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=DucTho%20Le">DucTho Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Duy%20Kien%20Dao"> Duy Kien Dao</a>, <a href="https://publications.waset.org/abstracts/search?q=Quoc%20Tinh%20Bui"> Quoc Tinh Bui</a>, <a href="https://publications.waset.org/abstracts/search?q=Haidang%20Phan"> Haidang Phan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article is concerned with the motion of ultrasonic guided waves in a unidirectional fiber-reinforced composite plate under acoustic sources. Such unidirectional composite material has orthotropic elastic properties as it is very stiff along the fibers and rather compliant across the fibers. The dispersion equations of free Lamb waves propagating in an orthotropic layer are derived that results in the dispersion curves. The connection of these equations to the Rayleigh-Lamb frequency relations of isotropic plates is discussed. By the use of reciprocity in elastodynamics, closed-form solutions of elastic wave motions subjected to time-harmonic loads in the layer are computed in a simple manner. We also consider the problem of Lamb waves generated by a set of time-harmonic sources. The obtained computations can be very useful for developing ultrasound-based methods for nondestructive evaluation of composite structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lamb%20waves" title="lamb waves">lamb waves</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber-reinforced%20composite%20plates" title=" fiber-reinforced composite plates"> fiber-reinforced composite plates</a>, <a href="https://publications.waset.org/abstracts/search?q=dispersion%20equations" title=" dispersion equations"> dispersion equations</a>, <a href="https://publications.waset.org/abstracts/search?q=nondestructive%20evaluation" title=" nondestructive evaluation"> nondestructive evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=reciprocity%20theorems" title=" reciprocity theorems"> reciprocity theorems</a> </p> <a href="https://publications.waset.org/abstracts/110250/study-of-ultrasonic-waves-in-unidirectional-fiber-reinforced-composite-plates-for-the-aerospace-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110250.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">149</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">2413</span> Predictive Modeling of Bridge Conditions Using Random Forest</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Miral%20Selim">Miral Selim</a>, <a href="https://publications.waset.org/abstracts/search?q=May%20Haggag"> May Haggag</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Abotaleb"> Ibrahim Abotaleb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aging of transportation infrastructure presents significant challenges, particularly concerning the monitoring and maintenance of bridges. This study investigates the application of Random Forest algorithms for predictive modeling of bridge conditions, utilizing data from the US National Bridge Inventory (NBI). The research is significant as it aims to improve bridge management through data-driven insights that can enhance maintenance strategies and contribute to overall safety. Random Forest is chosen for its robustness, ability to handle complex, non-linear relationships among variables, and its effectiveness in feature importance evaluation. The study begins with comprehensive data collection and cleaning, followed by the identification of key variables influencing bridge condition ratings, including age, construction materials, environmental factors, and maintenance history. Random Forest is utilized to examine the relationships between these variables and the predicted bridge conditions. The dataset is divided into training and testing subsets to evaluate the model's performance. The findings demonstrate that the Random Forest model effectively enhances the understanding of factors affecting bridge conditions. By identifying bridges at greater risk of deterioration, the model facilitates proactive maintenance strategies, which can help avoid costly repairs and minimize service disruptions.

Under various applied spring stiffness and dashpot coefficient, the expected hysteretic energy responses of the steel frame with damping panel systems we re investigated.

Q460GJ structural steel has a nominal yield strength of 460 MPa, which does not decrease significantly with the increase of steel plate thickness like normal structural steel. Thus, Q460GJ structural steel is normally used in medium-walled welded sections. However, research works on the residual stress in GJ steel members are few though it is one of the vital factors that can affect the member and structural behavior. This article aims to investigate the residual stresses in welded I-shaped sections fabricated from Q460GJ structural steel plates by experimental tests. A total of four full scale welded medium-walled I-shaped sections were tested by sectioning method. Both circular curve correction method and straightening measurement method were adopted in this study to obtain the final magnitude and distribution of the longitudinal residual stresses. In addition, this paper also explores the interaction between flanges and webs. And based on the statistical evaluation of the experimental data, a multilayer residual stress model is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Q460GJ%20structural%20steel" title="Q460GJ structural steel">Q460GJ structural steel</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20stresses" title=" residual stresses"> residual stresses</a>, <a href="https://publications.waset.org/abstracts/search?q=sectioning%20method" title=" sectioning method"> sectioning method</a>, <a href="https://publications.waset.org/abstracts/search?q=welded%20medium-walled%20I-shaped%20sections" title=" welded medium-walled I-shaped sections"> welded medium-walled I-shaped sections</a> </p> <a href="https://publications.waset.org/abstracts/66348/experimental-investigation-on-residual-stresses-in-welded-medium-walled-i-shaped-sections-fabricated-from-q460gj-structural-steel-plates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66348.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">317</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">2409</span> Flexural Strength of Alkali Resistant Glass Textile Reinforced Concrete Beam with Prestressing </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jongho%20Park">Jongho Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Taekyun%20Kim"> Taekyun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jungbhin%20You"> Jungbhin You</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungnam%20Hong"> Sungnam Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun-Kyu%20Park"> Sun-Kyu Park </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the aging of bridges, increasing of maintenance costs and decreasing of structural safety is occurred. The steel corrosion of reinforced concrete bridge is the most common problem and this phenomenon is accelerating due to abnormal weather and increasing CO<sub>2</sub> concentration due to climate change. To solve these problems, composite members using textile have been studied. A textile reinforced concrete can reduce carbon emissions by reduced concrete and without steel bars, so a lot of structural behavior studies are needed. Therefore, in this study, textile reinforced concrete beam was made and flexural test was performed. Also, the change of flexural strength according to the prestressing was conducted. As a result, flexural strength of TRC with prestressing was increased compared and flexural behavior was shown as reinforced concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AR-glass" title="AR-glass">AR-glass</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength" title=" flexural strength"> flexural strength</a>, <a href="https://publications.waset.org/abstracts/search?q=prestressing" title=" prestressing"> prestressing</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20reinforced%20concrete" title=" textile reinforced concrete"> textile reinforced concrete</a> </p> <a href="https://publications.waset.org/abstracts/74475/flexural-strength-of-alkali-resistant-glass-textile-reinforced-concrete-beam-with-prestressing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74475.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">331</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">2408</span> Development of a BriMAIN System for Health Monitoring of Railway Bridges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prakher%20Mishra">Prakher Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Dikshant%20Bodana"> Dikshant Bodana</a>, <a href="https://publications.waset.org/abstracts/search?q=Saloni%20Desai"> Saloni Desai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudhanshu%20Dixit"> Sudhanshu Dixit</a>, <a href="https://publications.waset.org/abstracts/search?q=Sopan%20Agarwal"> Sopan Agarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Shriraj%20Patel"> Shriraj Patel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Railways are sometimes lifeline of nations as they consist of huge network of rail lines and bridges.

It becomes a really challenging task for Engineers and workers to keep up a regular maintenance schedule for proper functioning which itself is quite a hard hitting job. In this paper we have come up with an innvovative wireless system of maintenance called BriMAIN. In this system we have installed two types of sensors, first one is called a force sensor which will continously analyse the readings of pressure at joints of the bridges and secondly an MPU-6050 triaxial gyroscope+accelerometer which will analyse the deflection of the deck of the bridge. Apart from this a separate database is also being made at the server room so that the data can be visualized by the engineers and a warning can be issued in case reading of the sensors goes above threshold. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Accelerometer" title="Accelerometer">Accelerometer</a>, <a href="https://publications.waset.org/abstracts/search?q=B-MAIN" title=" B-MAIN"> B-MAIN</a>, <a href="https://publications.waset.org/abstracts/search?q=Gyroscope" title=" Gyroscope"> Gyroscope</a>, <a href="https://publications.waset.org/abstracts/search?q=MPU-6050" title=" MPU-6050"> MPU-6050</a> </p> <a href="https://publications.waset.org/abstracts/77940/development-of-a-brimain-system-for-health-monitoring-of-railway-bridges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77940.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">383</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">2407</span> The Influence of Basalt and Steel Fibers on the Flexural Behavior of RC Beams </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasmin%20Z.%20Murad">Yasmin Z.

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">24</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">2405</span> Development of a Testing Rig for a Cold Formed-Hot Rolled Steel Hybrid Wall Panel System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mina%20Mortazavi">Mina Mortazavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Ronagh"> Hamid Ronagh</a>, <a href="https://publications.waset.org/abstracts/search?q=Pezhman%20Sharafi"> Pezhman Sharafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The new concept of a cold formed-hot rolled hybrid steel wall panel system is introduced to overcome the deficiency in lateral load resisting capacity of cold-formed steel structures. The hybrid system is composed of a cold-formed steel part laterally connected to hot rolled part. The hot rolled steel part is responsible for carrying the whole lateral load; while the cold formed steel part is only required to transfer the lateral load to the hot rolled part without any local failure. The vertical load is beared by both hot rolled, and cold formed steel part, proportionally. In order to investigate the lateral performance of the proposed system, it should be tested under simultaneous lateral and vertical load.

When choosing a vehicle model to depict the dynamic loading on the bridge structure caused by passing high-speed trains, different goals are pursued: On the one hand, the selected vehicle models should allow the calculation of a bridge’s vibrations as realistic as possible. On the other hand, the computational efficiency and manageability of the models should be preferably high to enable a wide range of applications. The commonly adopted and straightforward vehicle model is the moving load model (MLM), which simplifies the train to a sequence of static axle loads moving at a constant speed over the structure. However, the MLM can significantly overestimate the structure vibrations, especially when resonance events occur. More complex vehicle models, which depict the train as a system of oscillating and coupled masses, can reproduce the interaction dynamics between the vehicle and the bridge superstructure to some extent and enable the calculation of more realistic bridge accelerations. At the same time, such multi-body models require significantly greater processing capacities and precise knowledge of various vehicle properties. The European standards allow for applying the so-called additional damping method when simple load models, such as the MLM, are used in dynamic calculations. An additional damping factor depending on the bridge span, which should take into account the vibration-reducing benefits of the vehicle-bridge interaction, is assigned to the supporting structure in the calculations. However, numerous studies show that when the current standard specifications are applied, the calculation results for the bridge accelerations are in many cases still too high compared to the measured bridge accelerations, while in other cases, they are not on the safe side. A proposal to calculate the additional damping based on extensive dynamic calculations for a parametric field of simply supported bridges with a ballasted track was developed to address this issue. In this contribution, several different approaches to determine the additional damping of the supporting structure considering the vehicle-bridge interaction when using the MLM are compared with one another. Besides the standard specifications, this includes the approach mentioned above and two additional recently published alternative formulations derived from analytical approaches. For a bridge catalogue of 65 existing bridges in Austria in steel, concrete or composite construction, calculations are carried out with the MLM for two different high-speed trains and the different approaches for additional damping. The results are compared with the calculation results obtained by applying a more sophisticated multi-body model of the trains used. The evaluation and comparison of the results allow assessing the benefits of different calculation concepts for the additional damping regarding their accuracy and possible applications. The evaluation shows that by applying one of the recently published redesigned additional damping methods, the calculation results can reflect the influence of the vehicle-bridge interaction on the design-relevant structural accelerations considerably more reliable than by using normative specifications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Additional%20Damping%20Method" title="Additional Damping Method">Additional Damping Method</a>, <a href="https://publications.waset.org/abstracts/search?q=Bridge%20Dynamics" title=" Bridge Dynamics"> Bridge Dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=High-Speed%20Railway%20Traffic" title=" High-Speed Railway Traffic"> High-Speed Railway Traffic</a>, <a href="https://publications.waset.org/abstracts/search?q=Vehicle-Bridge-Interaction" title=" Vehicle-Bridge-Interaction"> Vehicle-Bridge-Interaction</a> </p> <a href="https://publications.waset.org/abstracts/137963/evaluation-of-alternative-approaches-for-additional-damping-in-dynamic-calculations-of-railway-bridges-under-high-speed-traffic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137963.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">161</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">2401</span> Behavior of GRS Abutment Facing under Variable Cycles of Lateral Excitation through Physical Model Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashutosh%20Verma">Ashutosh Verma</a>, <a href="https://publications.waset.org/abstracts/search?q=Satyendra%20Mittal"> Satyendra Mittal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerous geosynthetic reinforced soil (GRS) abutment failures over the years have been attributed to the loss of strength at the facing-reinforcement interface due to seasonal thermal expansion/contraction of the bridge deck. This causes excessive settlement below the bridge seat, causing bridge bumps along the approach road which reduces the design life of any abutment. Before designers while choosing the type of facing, a broad range of facing configurations are undoubtedly available. Generally speaking, these configurations can be divided into three groups: modular (panels/block), continuous, and full height rigid (FHR). The purpose of the current study is to use 1g physical model tests under serviceable cyclic lateral displacements to experimentally investigate the behaviour of these three facing classifications. To simulate field behaviour, a field instrumented GRS abutment prototype was modeled into a N scaled down 1g physical model (N = 5) with adjustable facing arrangements to represent these three facing classifications. For cyclic lateral displacement (d/H) of top facing at loading rate of 1mm/min, the peak earth pressure coefficient (K) on the facing and vertical settlement of the footing (s/B) at 25, 50, 75 and 100 cycles have been measured. For a constant footing offset of x/H = 0.1, three forms of cyclic displacements have been performed to simulate active condition (CA), passive condition (CP), and active-passive condition (CAP). The findings showed that when reinforcements are integrated into the wall along with presence of gravel gabions i.e. FHR design, a rather substantial earth pressure occurs over the facing. Despite this, the FHR facing's continuous nature works in conjunction with the reinforcements' membrane resilience to reduce footing settlement. On the other hand, the pressure over the wall is released upon lateral excitation by the relative displacement between the panels in modular facing reducing the connection strength at the interface and leading to greater settlements below footing. On the contrary, continuous facing do not exhibit relative displacement along the depth of facing rather fails through rotation about the base, which extends the zone of active failure in the backfill leading to large depressions in the backfill region around the bridge seat. Conservatively, FHR facing shows relatively stable responses under lateral cyclic excitations as compared to modular or continuous type of abutment facing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GRS%20abutments" title="GRS abutments">GRS abutments</a>, <a href="https://publications.waset.org/abstracts/search?q=1g%20physical%20model" title=" 1g physical model"> 1g physical model</a>, <a href="https://publications.waset.org/abstracts/search?q=full%20height%20rigid" title=" full height rigid"> full height rigid</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20lateral%20displacement" title=" cyclic lateral displacement"> cyclic lateral displacement</a> </p> <a href="https://publications.waset.org/abstracts/167801/behavior-of-grs-abutment-facing-under-variable-cycles-of-lateral-excitation-through-physical-model-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167801.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">83</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">2400</span> Study on Buckling and Yielding Behaviors of Low Yield Point Steel Plates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Boyajian">David Boyajian</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadeh%20Zirakian"> Tadeh Zirakian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stability and performance of steel plates are characterized by geometrical buckling and material yielding. In this paper, the geometrical buckling and material yielding behaviors of low yield point (LYP) steel plates are studied from the point of view of their application in steel plate shear wall (SPSW) systems. Use of LYP steel facilitates the design and application of web plates with improved buckling and energy absorption capacities in SPSW systems. LYP steel infill plates may yield first and then undergo inelastic buckling. Hence, accurate determination of the limiting plate thickness corresponding to simultaneous buckling and yielding can be effective in seismic design of such lateral force-resisting and energy dissipating systems. The limiting thicknesses of plates with different loading and support conditions are determined theoretically and verified through detailed numerical simulations. Effects of use of LYP steel and plate aspect ratio parameter on the limiting plate thickness are investigated as well. In addition, detailed studies are performed on determination of the limiting web-plate thickness in code-designed SPSWs. Some practical recommendations are accordingly provided for efficient seismic design of SPSW systems with LYP steel infill plates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling" title="buckling">buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20yield%20point%20steel" title=" low yield point steel"> low yield point steel</a>, <a href="https://publications.waset.org/abstracts/search?q=plates" title=" plates"> plates</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20plate%20shear%20walls" title=" steel plate shear walls"> steel plate shear walls</a>, <a href="https://publications.waset.org/abstracts/search?q=yielding" title=" yielding"> yielding</a> </p> <a href="https://publications.waset.org/abstracts/50611/study-on-buckling-and-yielding-behaviors-of-low-yield-point-steel-plates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50611.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">401</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">2399</span> Wear Resistance of 20MnCr5 Steel Nitrided by Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Okba%20Belahssen">Okba Belahssen</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Benramache"> Said Benramache</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents wear behavior of the plasma-nitrided 20MnCr5 steel.

It was a steel design and it had filled beam sections and truss beam systems. Columns were steel profiles and box sections. The factory was damaged heavily on Izmit Earthquake and closed. In this earthquake 90% of damaged structures are reinforced concrete, the others are %7 prefabricated and 3% steel construction. As can be seen in statistical data, damaged industrial buildings in this earthquake were generally reinforced concrete and prefabricated structures. Adapazari railway car factory is the greatest steel structure damaged in the earthquake. This factory has 95% of the total damaged steel structure area. In this paper; earthquake damages on beams and columns of the factory are studied by considering TS648 'Turkish Standard Building Code for Steel Structures' and also damaged connection elements as welds, rivets and bolts are examined. A model similar to the damaged system is made and high-stress zones are searched. These examinations, conclusions, suggestions are explained by damage photos and details. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=column-beam%20connection" title="column-beam connection">column-beam connection</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20analysis" title=" seismic analysis"> seismic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20load" title=" seismic load"> seismic load</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/45749/analysis-of-steel-beam-column-joints-under-seismic-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45749.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">277</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">2397</span> Three-Dimensional CFD Modeling of Flow Field and Scouring around Bridge Piers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Deepak%20Kumar">P.

Scour is the formation of scour hole around the structure mounted on and embedded in erodible channel bed due to the erosion of soil by flowing water. The formation of scour hole around the structures depends upon shape and size of the pier, depth of flow as well as angle of attack of flow and sediment characteristics. The flow characteristics around these structures change due to man-made obstruction in the natural flow path which changes the kinetic energy of the flow around these structures. Excessive scour affects the stability of the foundation of the structure by the removal of the bed material. The accurate estimation of scour depth around bridge pier is very difficult. The foundation of bridge piers have to be taken deeper and to provide sufficient anchorage length required for stability of the foundation. In this study, computational model simulations using a 3D Computational Fluid Dynamics (CFD) model were conducted to examine the mechanism of scour around a cylindrical pier. Subsequently, the flow characteristics around these structures are presented for different flow conditions. Mechanism of scouring phenomenon, the formation of vortex and its consequent effect is discussed for a straight channel. Effort was made towards estimation of scour depth around bridge piers under different flow conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge%20pier" title="bridge pier">bridge pier</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=multigrid" title=" multigrid"> multigrid</a>, <a href="https://publications.waset.org/abstracts/search?q=pier%20shape" title=" pier shape"> pier shape</a>, <a href="https://publications.waset.org/abstracts/search?q=scour" title=" scour"> scour</a> </p> <a href="https://publications.waset.org/abstracts/47338/three-dimensional-cfd-modeling-of-flow-field-and-scouring-around-bridge-piers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47338.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">296</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">2396</span> Vibration control of Bridge Super structure using Tuned Mass Damper (TMD)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tauhidur%20Rahman">Tauhidur Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhrubajyoti%20Thakuria"> Dhrubajyoti Thakuria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, vibration caused by earthquake excitation, wind load and the high-speed vehicle in the superstructure has been studied. An attempt has been made to control these vibrations using passive Tuned Mass Dampers (TMD). Tuned mass damper consists of a mass, spring, and viscous damper which dissipates the vibration energy of the primary structure at the damper of the TMD. In the present paper, the concrete box girder bridge superstructure is considered and is modeled using MIDAS software. The bridge is modeled as Euler-Bernoulli beam to study the responses imposed by high-speed vehicle, earthquake excitation and wind load. In the present study, comparative study for the responses has been done considering different velocities of the train. The results obtained in this study are based on Indian standard loadings specified in Indian Railways Board (Bridge Rules). A comparative study has been done for the responses of the high-speed vehicle with and without Tuned Mass Dampers. The results indicate that there is a significant reduction in displacement and acceleration in the bridge superstructure when Tuned Mass Damper is used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge%20superstructure" title="bridge superstructure">bridge superstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20speed%20vehicle" title=" high speed vehicle"> high speed vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=tuned%20mass%20damper" title=" tuned mass damper"> tuned mass damper</a>, <a href="https://publications.waset.org/abstracts/search?q=TMD" title=" TMD"> TMD</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20control" title=" vibration control"> vibration control</a> </p> <a href="https://publications.waset.org/abstracts/26465/vibration-control-of-bridge-super-structure-using-tuned-mass-damper-tmd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26465.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">403</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">2395</span> Overall Stability of Welded Q460GJ Steel Box Columns: Experimental Study and Numerical Simulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhou%20Xiong">Zhou Xiong</a>, <a href="https://publications.waset.org/abstracts/search?q=Kang%20Shao%20Bo"> Kang Shao Bo</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Bo"> Yang Bo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To date, high-performance structural steel has been widely used for columns in construction practices due to its significant advantages over conventional steel. However, the same design approach with conventional steel columns is still adopted in the design of high-performance steel columns. As a result, its superior properties cannot be fully considered in design. This paper conducts a test and finite element analysis on the overall stability behaviour of welded Q460GJ steel box columns. In the test, four steel columns with different slenderness and width-to-thickness ratio were compressed under an axial compression testing machine. And finite element models were established in which material nonlinearity and residual stress distributions of test columns were included. Then, comparisons were made between test results and finite element result, it showed that finite element analysis results are agree well with the test result. It means that the test and finite element model are reliable. Then, we compared the test result with the design value calculated by current code, the result showed that Q460GJ steel box columns have the higher overall buckling capacity than the design value.

In addition, modeling of the rational traction curves provides a work hardening coefficient of up to 0.3 in the presence of burnishing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=16NC6%20steel" title="16NC6 steel">16NC6 steel</a>, <a href="https://publications.waset.org/abstracts/search?q=burnishing" title=" burnishing"> burnishing</a>, <a href="https://publications.waset.org/abstracts/search?q=hardening" title=" hardening"> hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=roughness" title=" roughness"> roughness</a> </p> <a href="https://publications.waset.org/abstracts/128582/mechanical-behavior-of-16nc6-steel-hardened-by-burnishing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128582.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">164</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">2391</span> Effect of Local Steel Slag as a Coarse Aggregate in the Properties of Fly Ash Based-Geopolymer Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20M.%20Omar">O.

Using local steel slag waste as a hundred substitute of crushed stone in construction materials would resolve the environmental problems caused by the large-scale depletion of the natural sources of dolomite. This paper reports the experimental study to investigate the influence of a hundred replacement of dolomite as a coarse aggregate with local steel slag, on the fresh and hardened geopolymer concrete properties. The investigation includes traditional testing of hardening concrete, for selected mixes of cement and geopolymer concrete. It was found that local steel slag as a coarse aggregate enhanced the slump test of the fresh state of cement and geopolymer concretes. Nevertheless the unit weight of concretes was affected. Meanwhile, the good performance was observed when fly ash used as geopolymer concrete based. <p class="card-text"><strong>Keywords:</strong> <a
