摘要
设置变形缝给建筑设计及构造处理带来诸多复杂问题,一定程度上受到阻碍,然而设缝处理在结构设计中不可或缺。本文通过对某小区一幢高层住宅进行设置变形缝和不设缝两种情况下的动力特性及地震响应对比分析,重点探讨了变形缝设置对构件内力的影响。分析结果表明,高层结构设缝降低了结构扭转效应,对结构局部构件内力的调整极其显著,为结构设计提供了方便。
Setting deformation joint brings lots of complex problems to architectural design and structural measure;it is hampered to some extent.In fact the deformation joint is indispensable in some structural design.The key purpose of this paper is to discuss the influence of the deformation joint on the internal forces,obtained from the comparative analysis of dynamic characteristics and seismic responses with and without the deformation joint about a high-rise residential building.The analysis results show that the deformation joint settled can reduce the structural torsional response,extremely marked to the adjustment of the internal force of structure,provided it is convenient for structural design.
