摘要
利用有限元分析程序ETABS对振动台试验中的混凝土框架结构原型与模型结构进行了静力弹塑性pushover分析,研究内容包括:由pushover分析得到的结构在不同地震烈度时的性能点,结构的层间位移,塑性铰的出现次序及分布情况,对原型与模型结构的分析结果进行了比较。在此基础上,依据我国抗震规范对原型与模型结构的抗震性能水准进行了评价。
In this paper,inelastic static pushover analysis of prototype and model structure is completed by making use of the finite element analysis program ETABS.The content of study includes the performance point under different level earthquakes,the layer displacement,the distribution of the plastic hinges of the structure's components.The paper also compares the result of prototype and model structure.According to the code for seismic design of buildings,this paper evaluates the structural seismic performance level.
