钢管混凝土结构的弹塑性时程分析

Elasto-plastic time-history analysis of concrete filled steel tubular structure

利用杆系模型理论，对高层铜管混凝土结构简化模型进行非线性弹塑性时程分析。计算结果表明，本文计算模型合理，在８度罕遇地震作用下，该结构没有产生不可逆性破坏，说明该结构具有良好的抗震性能。

In this paper, the elasto plastic time-history analysis of CFST structure is discussed. The results show that no irreparable damage can generate in the structure under intense earthquake. which i1lustrate the CFST structure excel in seismic behavior.
