It is a difficult task to model ground behavior in seismic soil-structure-foundation interaction problems, fully account for them in seismic design of structures, or even properly consider them in seismic hazard assessment. In this study, we focused on applying seismic soil investigation methods, used for determining soil stiffness and damping properties, to response analysis used in seismic design. A site in Budapest, Hungary was investigated using Multichannel Analysis of Surface Waves, Seismic Cone Penetration Tests, Bender Elements, Resonant Column and Torsional Shear tests. Our aim was to compare the results of the different test methods and use the resulting soil properties for 1D ground response analysis. Often in practice, there are little-to no data available on dynamic soil properties and estimated parameters are used for design. Therefore, a comparison is made between results based on estimated parameters and those based on detailed investigations. Ground response results are also compared to Eurocode 8 design spectra. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MASW" title="MASW">MASW</a>, <a href="https://publications.waset.org/abstracts/search?q=resonant%20column%20test" title=" resonant column test"> resonant column test</a>, <a href="https://publications.waset.org/abstracts/search?q=SCPT" title=" SCPT"> SCPT</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20response%20analysis" title=" site response analysis"> site response analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=torsional%20shear%20test" title=" torsional shear test"> torsional shear test</a> </p> <a href="https://publications.waset.org/abstracts/67550/ground-response-analyses-in-budapest-based-on-site-investigations-and-laboratory-measurements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67550.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">400</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">31430</span> Seismic Vulnerability Analysis of Arch Dam Based on Response Surface Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Serges%20Mendomo%20Meye">Serges Mendomo Meye</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Guowei"> Li Guowei</a>, <a href="https://publications.waset.org/abstracts/search?q=Shen%20Zhenzhong"> Shen Zhenzhong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Earthquake is one of the main loads threatening dam safety. Once the dam is damaged, it will bring huge losses of life and property to the country and people. Therefore, it is very important to research the seismic safety of the dam. Due to the complex foundation conditions, high fortification intensity, and high scientific and technological content, it is necessary to adopt reasonable methods to evaluate the seismic safety performance of concrete arch dams built and under construction in strong earthquake areas. Structural seismic vulnerability analysis can predict the probability of structural failure at all levels under different intensity earthquakes, which can provide a scientific basis for reasonable seismic safety evaluation and decision-making. In this paper, the response surface method (RSM) is applied to the seismic vulnerability analysis of arch dams, which improves the efficiency of vulnerability analysis. Based on the central composite test design method, the material-seismic intensity samples are established. The response surface model (RSM) with arch crown displacement as performance index is obtained by finite element (FE) calculation of the samples, and then the accuracy of the response surface model (RSM) is verified. To obtain the seismic vulnerability curves, the seismic intensity measure ??(?1) is chosen to be 0.1~1.2g, with an interval of 0.1g and a total of 12 intensity levels. For each seismic intensity level, the arch crown displacement corresponding to 100 sets of different material samples can be calculated by algebraic operation of the response surface model (RSM), which avoids 1200 times of nonlinear dynamic calculation of arch dam; thus, the efficiency of vulnerability analysis is improved greatly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20concrete%20arch%20dam" title="high concrete arch dam">high concrete arch dam</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20index" title=" performance index"> performance index</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20method" title=" response surface method"> response surface method</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20vulnerability%20analysis" title=" seismic vulnerability analysis"> seismic vulnerability analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=vector-valued%20intensity%20measure" title=" vector-valued intensity measure"> vector-valued intensity measure</a> </p> <a href="https://publications.waset.org/abstracts/140363/seismic-vulnerability-analysis-of-arch-dam-based-on-response-surface-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140363.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">240</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">31429</span> Evaluation of Response Modification Factor and Behavior of Seismic Base-Isolated RC Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Parsaeimaram">Mohammad Parsaeimaram</a>, <a href="https://publications.waset.org/abstracts/search?q=Fang%20Congqi"> Fang Congqi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, one of the significant seismic design parameter as response modification factor in reinforced concrete (RC) buildings with base isolation system was evaluated.

The obtained seismic response was compared with the results of the seismic analysis obtained for the same steel frame that takes into account the monotonic model of the joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beam-to-column%20joints" title="beam-to-column joints">beam-to-column joints</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis%20envelope%20model" title=" hysteresis envelope model"> hysteresis envelope model</a>, <a href="https://publications.waset.org/abstracts/search?q=moment-resisting%20frame" title=" moment-resisting frame"> moment-resisting frame</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20static%20pushover%20analysis" title=" nonlinear static pushover analysis"> nonlinear static pushover analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=N2%20method" title=" N2 method"> N2 method</a> </p> <a href="https://publications.waset.org/abstracts/144790/seismic-response-of-moment-resisting-steel-frame-with-hysteresis-envelope-model-of-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144790.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">265</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">31427</span> Behaviour of Reinforced Concrete Infilled Frames under Seismic Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Badla">W.

However, these masonry panels tend to influence the structural response. Thus, these structures can be regarded as seismic risk buildings, although in the Algerian seismic code there is little guidance on the seismic evaluation of infilled frame buildings. In this study, three RC frames with 2, 4, and 8 story and subjected to three recorded Algerian accelerograms are studied. The diagonal strut approach is adopted for modeling the infill panels and a fiber model is used to model RC members. This paper reports on the seismic evaluation of RC frames with brick infill panels. The results obtained show that the masonry panels enhance the load lateral capacity of the buildings and the infill panel configuration influences the response of the structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20design" title="seismic design">seismic design</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20frames" title=" RC frames"> RC frames</a>, <a href="https://publications.waset.org/abstracts/search?q=infill%20panels" title=" infill panels"> infill panels</a>, <a href="https://publications.waset.org/abstracts/search?q=non%20linear%20dynamic%20analysis" title=" non linear dynamic analysis"> non linear dynamic analysis</a> </p> <a href="https://publications.waset.org/abstracts/21693/behaviour-of-reinforced-concrete-infilled-frames-under-seismic-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21693.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">546</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">31426</span> Seismic Performance Evaluation of Existing Building Using Structural Information Modeling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Byungmin%20Cho">Byungmin Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongchul%20Lee"> Dongchul Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Taejin%20Kim"> Taejin Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Minhee%20Lee"> Minhee Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The procedure for the seismic retrofit of existing buildings includes the seismic evaluation. In the evaluation step, it is assessed whether the buildings have satisfactory performance against seismic load. Based on the results of that, the buildings are upgraded. To evaluate seismic performance of the buildings, it usually goes through the model transformation from elastic analysis to inelastic analysis. However, when the data is not delivered through the interwork, engineers should manually input the data. In this process, since it leads to inaccuracy and loss of information, the results of the analysis become less accurate. Therefore, in this study, the process for the seismic evaluation of existing buildings using structural information modeling is suggested. This structural information modeling makes the work economic and accurate. To this end, it is determined which part of the process could be computerized through the investigation of the process for the seismic evaluation based on ASCE 41. The structural information modeling process is developed to apply to the seismic evaluation using Perform 3D program usually used for the nonlinear response history analysis. To validate this process, the seismic performance of an existing building is investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=existing%20building" title="existing building">existing building</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20analysis" title=" nonlinear analysis"> nonlinear analysis</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%20information%20modeling" title=" structural information modeling"> structural information modeling</a> </p> <a href="https://publications.waset.org/abstracts/31008/seismic-performance-evaluation-of-existing-building-using-structural-information-modeling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31008.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">384</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">31425</span> Regional Adjustment to the Analytical Attenuation Coefficient in the GMPM BSSA 14 for the Region of Spain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gonzalez%20Carlos">Gonzalez Carlos</a>, <a href="https://publications.waset.org/abstracts/search?q=Martinez%20Fransisco"> Martinez Fransisco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are various types of analysis that allow us to involve seismic phenomena that cause strong requirements for structures that are designed by society; one of them is a probabilistic analysis which works from prediction equations that have been created based on metadata seismic compiled in different regions.

In order to obtain accurate seismic responses using RHA, it is important to use adequate input ground motions. Current seismic design provisions provide criteria for selecting ground motions. In this study, the accurate and computationally efficient algorithm is proposed for accurately selecting ground motions that satisfy the requirements specified in current seismic design provisions. The accuracy of the proposed algorithm is verified using single-degree-of-freedom systems with various natural periods and yield strengths.

The principles of seismic analysis can be applied for different kinds of excitation such as: earthquakes, wind, explosions, random excitation from local transportation, periodic excitation from large rotating and/or machines with reciprocating motion, metal forming processes such as forging, shearing and stamping, chemical reactions, construction and earth moving work, and other strong deterministic and random energy sources caused by human activities. The article deals with the response of seismic, low frequency, mechanical vibrations generated by nearby blasting operations on a residential home. The goal was to determine the fundamental natural frequencies of the measured structure; therefore it is important to determine the resonant frequencies to design a suitable modal damping. The article also analyzes the package of seismic waves generated by blasting (Primary waves – P-waves and Secondary waves S-waves) and investigated the transfer regions. For the detection of seismic waves resulting from an explosion, the Fast Fourier Transform (FFT) and modal analysis, in the frequency domain, is used and the signal was acquired and analyzed also in the time domain. In the conclusions the measured results of seismic waves caused by blasting in a nearby quarry and its effect on a nearby structure (house) is analyzed. The response on the house, including the fundamental natural frequency and possible fatigue damage is also assessed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20structure" title="building structure">building structure</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20waves" title=" seismic waves"> seismic waves</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20analysis" title=" spectral analysis"> spectral analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20response" title=" structural response"> structural response</a> </p> <a href="https://publications.waset.org/abstracts/2072/analysis-of-seismic-waves-generated-by-blasting-operations-and-their-response-on-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2072.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">400</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">31421</span> Effects of Local Ground Conditions on Site Response Analysis Results in Hungary</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orsolya%20Kegyes-Brassai">Orsolya Kegyes-Brassai</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Szilv%C3%A1gyi"> Zsolt Szilvágyi</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81kos%20Wolf"> Ákos Wolf</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20P.%20Ray"> Richard P.

Their inclusion in seismic hazard assessment and structural design can be realized at different levels of sophistication. However, response results based on more advanced calculation methods e.g. nonlinear or equivalent linear site analysis tend to show significant discrepancies when compared to simpler approaches. This project's main objective was to compare results from several 1-D response programs to Eurocode 8 design spectra. Data from in-situ site investigations were used for assessing local ground conditions at several locations in Hungary. After discussion of the in-situ measurements and calculation methods used, a comprehensive evaluation of all major contributing factors for site response is given. While the Eurocode spectra should account for local ground conditions based on soil classification, there is a wide variation in peak ground acceleration determined from 1-D analyses versus Eurocode. Results show that current Eurocode 8 design spectra may not be conservative enough to account for local ground conditions typical for Hungary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=1-D%20site%20response%20analysis" title="1-D site response analysis">1-D site response analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=multichannel%20analysis%20of%20surface%20waves%20%28MASW%29" title=" multichannel analysis of surface waves (MASW)"> multichannel analysis of surface waves (MASW)</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20CPT" title=" seismic CPT"> seismic CPT</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20hazard%20assessment" title=" seismic hazard assessment"> seismic hazard assessment</a> </p> <a href="https://publications.waset.org/abstracts/67541/effects-of-local-ground-conditions-on-site-response-analysis-results-in-hungary" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67541.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">246</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">31420</span> Seismic Fragility Functions of RC Moment Frames Using Incremental Dynamic Analyses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seung-Won%20Lee">Seung-Won Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=JongSoo%20Lee"> JongSoo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Won-Jik%20Yang"> Won-Jik Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung-Joon%20Kim"> Hyung-Joon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A capacity spectrum method (CSM), one of methodologies to evaluate seismic fragilities of building structures, has been long recognized as the most convenient method, even if it contains several limitations to predict the seismic response of structures of interest. This paper proposes the procedure to estimate seismic fragility curves using an incremental dynamic analysis (IDA) rather than the method adopting a CSM. To achieve the research purpose, this study compares the seismic fragility curves of a 5-story reinforced concrete (RC) moment frame obtained from both methods, an IDA method and a CSM. Both seismic fragility curves are similar in slight and moderate damage states whereas the fragility curve obtained from the IDA method presents less variation (or uncertainties) in extensive and complete damage states. This is due to the fact that the IDA method can properly capture the structural response beyond yielding rather than the CSM and can directly calculate higher mode effects. From these observations, the CSM could overestimate seismic vulnerabilities of the studied structure in extensive or complete damage states. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20fragility%20curve" title="seismic fragility curve">seismic fragility curve</a>, <a href="https://publications.waset.org/abstracts/search?q=incremental%20dynamic%20analysis" title=" incremental dynamic analysis"> incremental dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=capacity%20spectrum%20method" title=" capacity spectrum method"> capacity spectrum method</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20moment%20frame" title=" reinforced concrete moment frame"> reinforced concrete moment frame</a> </p> <a href="https://publications.waset.org/abstracts/21652/seismic-fragility-functions-of-rc-moment-frames-using-incremental-dynamic-analyses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21652.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">422</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">31419</span> Seismic Soil-Pile Interaction Considering Nonlinear Soil Column Behavior in Saturated and Dry Soil Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Moeini">Mohammad Moeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Ghyabi"> Mehrdad Ghyabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiarash%20Mohtasham%20Dolatshahi"> Kiarash Mohtasham Dolatshahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates seismic soil-pile interaction using the Beam on Nonlinear Winkler Foundation (BNWF) approach.

Comparison of the results shows that consideration of the structure geometry is vital in dynamic analysis and leads to the changes in the magnitude of displacements, accelerations and response spectrum. Therefore it is necessary for the surface structures to be wholly modeled and not just considered as a surcharge in dynamic analysis. The use of twin tunnel also leads to the reduction of dynamic residual settlement<span dir="RTL">.</span> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=superstructure" title="superstructure">superstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=tunnel" title=" tunnel"> tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20response" title=" site response"> site response</a>, <a href="https://publications.waset.org/abstracts/search?q=surcharge" title=" surcharge"> surcharge</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction" title=" interaction"> interaction</a> </p> <a href="https://publications.waset.org/abstracts/106616/seismic-investigation-on-the-effect-of-surface-structures-and-twin-tunnel-on-the-site-response-in-urban-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106616.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">31416</span> Dynamic Analysis of Submerged Floating Tunnel Subjected to Hydrodynamic and Seismic Loadings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naik%20Muhammad">Naik Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Ullah"> Zahid Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Ho%20Choi"> Dong-Ho Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Submerged floating tunnel (SFT) is a new solution for the transportation infrastructure through sea straits, fjords, and inland waters, and can be a good alternative to long span suspension bridges. SFT is a massive cylindrical structure that floats at a certain depth below the water surface and subjected to extreme environmental conditions. The identification of dominant structural response of SFT becomes more important due to intended environmental conditions for the design of SFT. The time domain dynamic problem of SFT moored by vertical and inclined mooring cables/anchors is formulated. The dynamic time history analysis of SFT subjected to hydrodynamic and seismic excitations is performed. The SFT is modeled by finite element 3D beam, and the mooring cables are modeled by truss elements. Based on the dynamic time history analysis the displacements and internal forces of SFT were calculated. The response of SFT is presented for hydrodynamic and seismic excitations. The transverse internal forces of SFT were the maximum compared to vertical direction, for both hydrodynamic and seismic cases; this indicates that the cable system provides very small stiffness in transverse direction as compared to vertical direction of SFT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=submerged%20floating%20tunnel" title="submerged floating tunnel">submerged floating tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodynamic%20analysis" title=" hydrodynamic analysis"> hydrodynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20history%20analysis" title=" time history analysis"> time history analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20response" title=" seismic response"> seismic response</a> </p> <a href="https://publications.waset.org/abstracts/68033/dynamic-analysis-of-submerged-floating-tunnel-subjected-to-hydrodynamic-and-seismic-loadings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68033.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">329</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">31415</span> Seismic Hazard Assessment of Offshore Platforms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20D.%20Konstandakopoulou">F.

With a large number of earthquakes occurring in day to day life, the threat to life and property has increased manifolds which call for an urgent attention of all the researchers globally to carry out the research in the field of Earthquake Engineering. Any hazard related to the earthquake and seismicity is considered to be seismic hazards. The common forms of seismic hazards are Ground Shaking, Structure Damage, Structural Hazards, Liquefaction, Landslides, Tsunami to name a few. Among all the natural hazards, the most devastating and damaging is the earthquake as all other hazards are triggered only after the occurrence of an earthquake. In order to quantify and estimate the seismicity and seismic hazards, many methods and approaches have been proposed in the past few years. Such approaches are Mathematical, Conventional and Computational. Convex Set Theory, Empirical Green’s Function are some of the Mathematical Approaches whereas the Deterministic and Probabilistic Approaches are the Conventional Approach for the estimation of the seismic Hazards. Ground response and Ground Shaking of a particular area or region plays an important role in the damage caused due to the earthquake. In this paper, seismic study using Deterministic Approach and 1 D Ground Response Analysis has been carried out for Madhya Pradesh Tourism Office in Indore Region in Madhya Pradesh in Central India. Indore lies in the seismic zone III (IS: 1893, 2002) in the Seismic Zoning map of India. There are various faults and lineament in this area and Narmada Some Fault and Gavilgadh fault are the active sources of earthquake in the study area. Deepsoil v6.1.7 has been used to perform the 1 D Linear Ground Response Analysis for the study area. The Peak Ground Acceleration (PGA) of the city ranges from 0.1g to 0.56g. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismicity" title="seismicity">seismicity</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20hazards" title=" seismic hazards"> seismic hazards</a>, <a href="https://publications.waset.org/abstracts/search?q=deterministic" title=" deterministic"> deterministic</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20methods" title=" probabilistic methods"> probabilistic methods</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20response%20analysis" title=" ground response analysis"> ground response analysis</a> </p> <a href="https://publications.waset.org/abstracts/77022/seismicity-and-ground-response-analysis-for-mp-tourism-office-in-indore-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77022.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">165</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">31413</span> Study of the Influence of Eccentricity Due to Configuration and Materials on Seismic Response of a Typical Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Latif%20Karimi">A.

It includes strategies for designing earthquake-resistant buildings to ensure health, safety, and security of the building occupants and assets. Hence, it becomes very important to understand the behavior of structural members precisely, for construction of buildings that can yield a better response to seismic forces. This paper investigates the behavior of a typical structure when subjected to ground motion. The corresponding mode shapes and modal frequencies are studied to interpret the response of an actual structure using different fabricated models and 3D visual models. In this study, three different structural configurations are subjected to horizontal ground motion, and the effect of “stiffness eccentricity” and placement of infill walls are checked to determine how each parameter contributes in a building’s response to dynamic forces. The deformation data from lab experiments and the analysis on SAP2000 software are reviewed to obtain the results. This study revealed that seismic response in a building can be improved by introducing higher deformation capacity in the building. Also, proper design of infill walls and maintaining a symmetrical configuration in a building are the key factors in building stability during the earthquake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eccentricity" title="eccentricity">eccentricity</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20response" title=" seismic response"> seismic response</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20shape" title=" mode shape"> mode shape</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20configuration" title=" building configuration"> building configuration</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20dynamics" title=" building dynamics"> building dynamics</a> </p> <a href="https://publications.waset.org/abstracts/90832/study-of-the-influence-of-eccentricity-due-to-configuration-and-materials-on-seismic-response-of-a-typical-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90832.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">200</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">31412</span> Effects of Damper Locations and Base Isolators on Seismic Response of a Building Frame</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azin%20Shakibabarough">Azin Shakibabarough</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Valinejadshoubi"> Mojtaba Valinejadshoubi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashutosh%20Bagchi"> Ashutosh Bagchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Structural vibration means repetitive motion that causes fatigue and reduction of the performance of a structure. An earthquake may release high amount of energy that can have adverse effect on all components of a structure. Therefore, decreasing of vibration or maintaining performance of structures such as bridges, dams, roads and buildings is important for life safety and reducing economic loss. When earthquake or any vibration happens, investigation on parts of a structure which sustain the seismic loads is mandatory to provide a safe condition for the occupants. One of the solutions for reducing the earthquake vibration in a structure is using of vibration control devices such as dampers and base isolators. The objective of this study is to investigate the optimal positions of friction dampers and base isolators for better seismic response of 2D frame. For this purpose, a two bay and six story frame with different distribution formats was modeled and some of their responses to earthquake such as inter-story drift, max joint displacement, max axial force and max bending moment were determined and compared using non-linear dynamic analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fast%20nonlinear%20analysis" title="fast nonlinear analysis">fast nonlinear analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20damper" title=" friction damper"> friction damper</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20isolator" title=" base isolator"> base isolator</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20vibration%20control" title=" seismic vibration control"> seismic vibration control</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20response" title=" seismic response"> seismic response</a> </p> <a href="https://publications.waset.org/abstracts/50373/effects-of-damper-locations-and-base-isolators-on-seismic-response-of-a-building-frame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50373.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">321</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">31411</span> Seismic Response and Sensitivity Analysis of Circular Shallow Tunnels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Khadijah%20Che%20Osmi">Siti Khadijah Che Osmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Ahmad%20Syed"> Mohammed Ahmad Syed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Underground tunnels are one of the most popular public facilities for various applications such as transportation, water transfer, network utilities and etc. Experience from the past earthquake reveals that the underground tunnels also become vulnerable components and may damage at certain percentage depending on the level of ground shaking and induced phenomena. In this paper a numerical analysis is conducted in evaluating the sensitivity of two types of circular shallow tunnel lining models to wide ranging changes in the geotechnical design parameter. Critical analysis has been presented about the current methods of analysis, structural typology, ground motion characteristics, effect of soil conditions and associated uncertainties on the tunnel integrity. The response of the tunnel is evaluated through 2D non-linear finite element analysis, which critically assesses the impact of increasing levels of seismic loads.

Both investigated bridges are tree span continuous RC curved bridges with the difference in column shapes. First bridge (type A) has a wall-type pier and second (type B) has a two-column bent with circular columns. Bridges are designed according to European standards: EN 1991-2, EN1992-1-1 and EN 1998-2. Aim of the performed analysis is to compare seismic behavior of these two structures and to detect the influence of column shapes on the seismic response. Seismic risk assessment is carried out by obtaining demand fragility curves. Non-linear model was constructed and time-history analysis was performed using thirty five pairs of horizontal ground motions selected to match site specific hazard. In performance based analysis, peak column drift ratio (CDR) was selected as engineering demand parameter (EDP). For seismic intensity measure (IM) spectral displacement was selected. Demand fragility curves that give probability of exceedance of certain value for chosen EDP were constructed and based on them conclusions were made. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RC%20curved%20bridge" title="RC curved bridge">RC curved bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=demand%20fragility%20curve" title=" demand fragility curve"> demand fragility curve</a>, <a href="https://publications.waset.org/abstracts/search?q=wall%20type%20column" title=" wall type column"> wall type column</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20time-history%20analysis" title=" nonlinear time-history analysis"> nonlinear time-history analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=circular%20column" title=" circular column"> circular column</a> </p> <a href="https://publications.waset.org/abstracts/48878/comparison-of-seismic-response-for-two-rc-curved-bridges-with-different-column-shapes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48878.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">341</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">31409</span> Alternative Method of Determining Seismic Loads on Buildings Without Response Spectrum Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Razmik%20Atabekyan">Razmik Atabekyan</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20Atabekyan"> V. Atabekyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article discusses a new alternative method for determination of seismic loads on buildings, based on resistance of structures to deformations of vibrations. The basic principles for determining seismic loads by spectral method were developed in 40… 50ies of the last century and further have been improved to pursuit true assessments of seismic effects. The base of the existing methods to determine seismic loads is response spectrum or dynamicity coefficient β (norms of RF), which are not definitively established. To this day there is no single, universal method for the determination of seismic loads and when trying to apply the norms of different countries, significant discrepancies between the results are obtained. On the other hand there is a contradiction of the results of macro seismic surveys of strong earthquakes with the principle of the calculation based on accelerations. It is well-known, on soft soils there is an increase of destructions (mainly due to large displacements), even though the accelerations decreases. Obviously, the seismic impacts are transmitted to the building through foundation, but paradoxically, the existing methods do not even include foundation data. Meanwhile acceleration of foundation of the building can differ several times from the acceleration of the ground. During earthquakes each building has its own peculiarities of behavior, depending on the interaction between the soil and the foundations, their dynamic characteristics and many other factors. In this paper we consider a new, alternative method of determining the seismic loads on buildings, without the use of response spectrum. The following main conclusions: 1) Seismic loads are revealed at the foundation level, which leads to redistribution and reduction of seismic loads on structures. 2) The proposed method is universal and allows determine the seismic loads without the use of response spectrum and any implicit coefficients. 3) The possibility of taking into account important factors such as the strength characteristics of the soils, the size of the foundation, the angle of incidence of the seismic ray and others. 4) Existing methods can adequately determine the seismic loads on buildings only for first form of vibrations, at an average soil conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20loads" title="seismic loads">seismic loads</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20spectrum" title=" response spectrum"> response spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20characteristics%20of%20buildings" title=" dynamic characteristics of buildings"> dynamic characteristics of buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=momentum" title=" momentum"> momentum</a> </p> <a href="https://publications.waset.org/abstracts/22073/alternative-method-of-determining-seismic-loads-on-buildings-without-response-spectrum-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22073.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">505</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">31408</span> Dynamic Test and Numerical Analysis of Twin Tunnel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Changwon%20Kwak">Changwon Kwak</a>, <a href="https://publications.waset.org/abstracts/search?q=Innjoon%20Park"> Innjoon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongin%20Jang"> Dongin Jang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seismic load affects the behavior of underground structure like tunnel broadly.

Therefore, seismicity studies and seismic zonation of seismic zones of the country are necessary. In this article, the effect of local site conditions on the characteristics of seismic design in Rahmormoz will be examined. After analyzing the seismic hazard for Rahmormoz through deterministic and statistical methods and preparing the necessary geotechnical models based on available data, the ground response will be analyzed for different parts of the city based on four inputs and acceleration level estimated for bedrock through the equivalent linear method and by means of Deep Soil program.
