Initially (Phase 1), a linear response spectrum analysis was performed to verify the potential for crack formation. The result shows the possibility of developing cracks in the upstream face of the dam close to the lowest gallery, which were sufficiently long that the dam would not be stable following the earthquake. The results show the dam has potentially inadequate seismic and post-earthquake resistance and recommended an update of the stability analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crack%20propgation" title="crack propgation">crack propgation</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20gravity%20dam" title=" concrete gravity dam"> concrete gravity dam</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=assesment" title=" assesment"> assesment</a> </p> <a href="https://publications.waset.org/abstracts/176151/crack-propagation-in-concrete-gravity-dam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176151.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">78</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">2</span> Shock Response Analysis of Soil-Structure Systems Induced by Near-Fault Pulses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Masaeli">H.

Vibration transmissibility of the soil鈥搒tructure systems is evaluated by Shock Response Spectra (SRS). Medium鈥搕o鈥揾igh rise buildings with different aspect ratios located on different soil types as well as different foundations with respect to vertical load bearing safety factors are studied. Two types of mathematical near鈥揻ault pulses, i.e. forward directivity and fling step, with different pulse periods as well as pulse amplitudes are selected as incident ground shock. Linear versus nonlinear Soil鈥揝tructure Interaction (SSI) condition are considered alternatively and the corresponding results are compared. The results show that nonlinear SSI is likely to amplify the acceleration responses when subjected to long鈥損eriod incident pulses with normalized period exceeding a threshold. It is also shown that this threshold correlates with soil type, so that increased shear鈥搘ave velocity of the underlying soil makes the threshold period decrease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20soil%E2%80%93structure%20interaction" title="nonlinear soil鈥搒tructure interaction">nonlinear soil鈥搒tructure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20response%20spectrum" title=" shock response spectrum"> shock response spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=near%E2%80%93fault%20ground%20shock" title=" near鈥揻ault ground shock"> near鈥揻ault ground shock</a>, <a href="https://publications.waset.org/abstracts/search?q=rocking%20isolation" title=" rocking isolation"> rocking isolation</a> </p> <a href="https://publications.waset.org/abstracts/6203/shock-response-analysis-of-soil-structure-systems-induced-by-near-fault-pulses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6203.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">323</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">1</span> Effects of Soil-Structure Interaction on Seismic Performance of Steel Structures Equipped with Viscous Fluid Dampers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faramarz%20Khoshnoudian">Faramarz Khoshnoudian</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Vosoughiyan"> Saeed Vosoughiyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main goal of this article is to clarify the soil-structure interaction (SSI) effects on the seismic performance of steel moment resisting frame buildings which are rested on soft soil and equipped with viscous fluid dampers (VFDs). For this purpose, detailed structural models of a ten-story SMRF with VFDs excluding and including the SSI are constructed first. In order to simulate the dynamic response of the foundation, in this paper, the simple cone model is applied. Then, the nonlinear time-history analysis of the models is conducted using three kinds of earthquake excitations with different intensities. The analysis results have demonstrated that the SSI effects on the seismic performance of a structure equipped with VFDs and supported by rigid foundation on soft soil need to be considered. Also VFDs designed based on rigid foundation hypothesis fail to achieve the expected seismic objective while SSI goes into effect. <p class="card-text"><strong>Keywords:</strong> <a
