【摘要】 静力弹塑性Pushover分析是目前广泛使用的一种基于性能的抗震分析方法。本文论述静力弹塑性Pushover分析方法的基本原理,对10层网格式框架在8度罕遇地震下的抗震性能进行评估,结果表明,塑性铰首先出现在层间梁上,然后向楼面梁和柱上发展,能够较好满足大震不倒的抗震设防要求。更多还原

【Abstract】 Pushover analysis is a handy method for structure seismic evaluation,which is widely used. The theory of Pushover Analysis was explored,and the evaluation of ten-story grid frame in rare earthquake was analyzed.The method has been found that the order of plastic hinge is from middle beam to storey beam then column,and the structure can meet earthquake seismic requirements better.更多还原
