摘要
Pushover分析是一种基于位移的弹塑性分析方法,近年来在国内外得到了广泛的重视和利用。本文利用OpenSees对多遇、设防、罕遇地震作用下的六层钢筋混凝土结构进行推覆分析,得到结构的顶点位移和基底剪力、性能点。结果表明:结构基底剪力随着顶点位移的增长呈现先增后减的趋势;结构的性能点位移随着地震作用的变大而增加。
Pushover analysis ,which is widely recognized and used in domestic and overseas, is an elastic - plastic method based on displacement. Pushover analysis with OpenSees is used to analyze a six - story frame structure to obtain top displacement,base shear force,performance point under frequently, fortification and rarely earthquake. Results show that the base shear of the structure will increase firstly and then decrease as the increment of structure＇ s top displacement; the displacement of performance point will increase with earthquake effect.
