带高位转换层框—筒结构抗震性能分析

Seismic behavior analysis in frame-tube structure with high transfer storey

通过对工程实例的分析,比较转换层位于不同位置的框—筒结构的抗震性能和受力特点,指出带高位转换层的框—筒结构在转换层附近将产生刚度突变和剪力突变,并分析了在6度区带高位转换的框—筒结构的合理高位。

This paper discusses the seismic behavior and bearing power characteristic of transfer floor located at a different higher level in the frame-tube structure. It indicates the abrupt changes of the lateral stiffness and shear forces near the high transfer storey in frame-tube structure. Based on the results, reasonable location of the transfer storey can be determined at the sixth intensity level of seismic effort.
