【摘要】 对某超限高位转换的高层建筑进行了罕遇地震作用下的弹塑性时程分析,验算了弹塑性层间位移角限值,找出了结构薄弱部位。根据验算结果修改工程结构,改善了结构延性,从而提高结构的抗震性能,对同类高位转换的结构设计提出了建议和参考。更多还原

【Abstract】 Elastic and plastic time-history analysis of high transfer floor of a tall building under rare earthquake is carried out to check the elastic-plastic angular displacement limits and to find the weak points of the structure.According to the calculating results,the structural model is modified to improve ductility and seismic performance.Suggestions on the same kind of structural design of building with high transfer floor are put forward as an reference.更多还原
