混凝土桁架隔层错跨布置的剪力墙结构的时程分析
|
摘要
本文介绍了一种新型的高层剪力墙结构——混凝土桁架隔层错跨剪力墙结构.该结构为建筑设计提供较大的空间,并且自重小.为比较跳层桁架剪力墙和传统跳层剪力墙的抗震性能,分别建立了一种跳层桁架剪力墙结构和一种传统跳层剪力墙结构的三维计算模型,利用有限元软件SAP2000对结构进行模拟地震分析.计算结果表明,虽然较跳层桁架剪力墙位移大,但仍能满足规范侧移的要求,说明有比较广阔的应用前景.
A new type of high- rise shear wall structure whose Concrete truss is using staggered. Provide larger space for the architectural, and the weight is small. To compare the skip- floor shear wall and the seismic performance of traditional skip- floor shear wall, respectively, skip- floor shear wall structure is established and a kind of traditional skip- floor shear wall structure of the three- dimensional calculation model, using the finite element software SAP2000 simulated seismic analysis of structure, the calculation results show that although skip- floor shear wall displacement is large, but still can meet the requirements of specification lateral, suggests that there is a broad application prospect.
