摘要
本文基于实际工程的需要 ,分析了异形柱框架结构的抗震性能。通过建立两种框架结构模型 ,用振型分解法和动力时程法求得两种结构在水平地震作用下的弹性地震反应。结果表明 ,异形柱框架结构的抗震性能比矩形柱框架结构有明显的提高。并指出 ,异形柱框架结构抗震性能提高的主要原因是建筑物总体质量较轻。
The paper analyses the anti\|seismic performance of the frame constructed by special type pillars. On the basis of two mechanic models of deferent frame structures, it has been proved that the anti\|seismic performance of the frame constructed by special type pillars is obviously better than that of normal frame structure by use of the methods of vibration decomposition and dynamic time distance. Meanwhile, the paper shows that the improvement of anti\|seismic performance of the frame with special type pillars is mainly due to the lower mass of general building. \[
