| 摘 要： | 地铁换乘站由于功能要求,多为复杂的不规则结构.本文通过对一具有实际工程背景的地铁换乘站进行地震响应弹塑件时程分析,着重从结构的位移响应、侧向变形以及结构柱的内力响应等方面考察了不规则结构对其地震响应的影响.结果表明:周围土体的约束作用有利于减轻地下不规则结构的扭转效应;结构的竖向不规则性对地震响应产生的影响不仅与结构竖...

| Abstract: | The subway transfer stations are mostly complex irregular structures in order to meet the functional requirements.By means of the seismic elasto-plastic time-history analysis of a subway transfer station based on practical engineering,the influence of irregular structure on its seismic responses is investigated in this paper from the respects,such as the structural displacement responses,the structural lateral deformations and the internal force responses of structure columns.The results show that the restr... |
