SEISMIC PERFORMANCE STUDY ON RC WALL BUILDINGS FROM PUSHOVER ANALYSIS

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.

Effect of seismic sequences on fragility of Iranian code-conforming shear wall RC buildings

Background and objective: Estimating the vulnerability rate of urban textures in seismic incident following a major earthquake (aftershocks) is crucial in decision making and crisis management. For this purpose, it is necessary to calculate the vulnerability of buildings due to the successive incidents and to use them in the vulnerability estimation for probable future aftershocks. Seismic frag...

Seismic Vulnerability Analysis of RC Buildings in Western China

Probabilstic Seismic Risk Evaluation of Rc Buildings

As more and more emphasis is being laid on non-linear analysis of RC framed structures subjected to earthquake excitation, the research and development on both non-linear static (pushover) analysis as well as nonlinear dynamic (time history)analysis is in the forefront. Due to prohibitive computational time and efforts required to perform a complete nonlinear dynamic analysis, researchers and d...

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...
