Pushover Analysis of Piles in Stratified Soil

Pile foundations have been the subject of interest for earthquake engineers since last several decades. The devastations caused in major earthquakes of the world can be the reason enough to carry out the research on the topic of seismic behavior of piles. One definite concern is liquefaction induced ground movement after the shaking in an earthquake, causing extra lateral loads acting on piles....

Modal Pushover Analysis of SAC Buildings

The nonlinear static procedure (NSP) or pushover analysis in FEMA-273 [FEMA, 1997] has become a standard procedure in current structural engineering practice. Seismic demands are computed by nonlinear static analysis of the structure, which is subjected to monotonically increasing lateral forces with an invariant height-wise distribution until a target displacement is reached. None of the curre...

Performance-Based Seismic Assessment of Shallow Tunnels Using Pushover Analysis

این مقاله قصد دارد که با استفاده از تحلیل بارافزون به تحلیل لرزه ای بر مبنای عملکرد پوشش تونل های کم عمقی که در خاک ساخته شده اند و تحت بارگذاری موج برشی قائم قرار گرفته اند بپردازد. تحلیل بارافزون یک تحلیل استاتیک غیرخطی است که بر اساس جابجا کردن جانبی مدل دو بعدی خاک و تونل عمل می‌کند. این تحلیل تنها مود تغییر شکل اعوجاج (رکینگ) مقطع عرضی پوشش تونل را ارزیابی می‌کند و نسبت به سایر روشهای عددی...

Modal Pushover Seismic Analysis of Sac Buildings excluding Gravity Loads

Evaluated is the accuracy of the modal pushover analysis in estimating the seismic demands for six SAC buildings, excluding gravity-loads and P-delta effects. These results are compared with those obtained by nonlinear response history analysis and three force distributions in FEMA-273.
