带厚板转换层结构的静力弹塑性分析

Pushover Analysis of Structures with Transfer Slabs

带转换层的高层结构由于其较好的经济效益越来越受到欢迎.因厚板转换结构在抗震设计上存在的问题较多,在地震区应用的经验较少,故规范对带厚板转换结构的使用进行了严格的限制.采用静力弹塑性分析方法对一带厚板转换的结构进行罕遇地震下的受力分析.结果表明,厚板在罕遇地震下仍处于弹性阶段,具有良好的表现性能,结构的变形满足规范要求.

Tall buildings with transfer structure become more and more popular for its better economic benefits. However the use of structures with thick slabs is strictly constrained in the existing building codes and standards as they still have many problems with the design method and are less applied in seismic re- gion. Pushover Analysis was conducted to examine the response of a structure with thick slabs under the action of a rare earthquake. The analysis shows that thick slab performs well in the earthquake and the structure deformation meets the rules of the codes and standards.
