seismic ground motion is profoundly affected by geometrical and mechanical properties of soil deposits overlaying bedrock. local seismic ground response of saturated soil deposits was studied in literature by applying the effects of soil stress state and index properties on the strain-dependent normalized shear modulus reduction, g/g0, and damping ratio, d, curves in an equivalent linear analys...

this study aims to develop seismic fragility curves for a typical pile-supported wharf. fragility curve is one of the popular tools in seismic performance evaluation of a structure. the software flac2d was used to simulate the seismic performance of the wharf structure. using eight time history records, occurred in past, as seismic loading, incremental dynamic analysis (ida) was applied for sei...

In force-based seismic design, the behavior factor q (or response modification R) is devised to prevent overdesign by reducing design force. Different values of are available for various structure types. However, masonry fence walls not categorized in current codes. These poor quality due absence proper assurance and maintenance, most those structures inclined. this study, leaning experimentall...

This study investigates the sensitivity of design variables such as ultimate strength of concrete, yield stress of reinforcing steel and damping ratio to the seismic response of staggered wall structures. Two different methods for sensitivity analysis, the tornado diagram method and the first-order second-moment method, are applied to two types of model structures. Non-linear dynamic analyses a...

The city of Kolkata, the State Capital of West Bengal is jolted by earthquakes time and again from the tectonic regimes of the Central Himalaya, highly seismogenic Northeast India and the active tectonics of Bengal Basin which is a pericratonic tertiary basin on which the City is located. Earthquake disaster mitigation and management necessitates seismic hazard assessment for the generation of ...

background: the role of mesenchymal stem cell in cellular therapy is the subject of interest for many researchers. the differentiation potential of mscs and abilities in modulations of the recipient’s immune system makes them important cells in tissue regenerative studies. mscs by releasing the proinflammatory cytokines play important role in immunomodulatory systems; however the signaling path...

Seismic performance of a building is commonly evaluated by applying same design ground motions at each foundation. However, local soil conditions beneath likely vary, and these variations could result in out-of-phased the foundation locations. In this study, building’s responses during earthquakes were analyzed compared using out-of-phase motions. The 10-story, 90m-wide, reinforced concrete str...

nonlinear static procedure (nsp) is a common technique to predict seismic demands on various building structures by subjecting a monotonically increasing horizontal loading (pushover) to the structure. therefore, the pushover analysis is an important part of each nsp. accordingly, the current paper aims at investigating the efficiencyof various algorithms of lateral load patterns applied to the...

The seismic response of base-isolated structures is notably influenced by mechanical properties isolation devices due to their essential role in structural behavior. Consequently, the variability such should be accounted for design process. current codes prescribe a simplified approach based on analyses two extreme situations resulting from upper and lower bound bearings (upper analyses). In ca...

Abstract During the last three decades, interest in application of steel shear walls has increased worldwide. Steel are used as stiffened and unstiffened walls. One main shortcomings plate wall (SPSW) is infill buckling mainly under lateral wind seismic loads. useful solutions to prevent use with corrugated plates. In this research, behavior a consisting two plates was investigated material cas...
