摘要
本文通过实验的方法，研究了钢管混凝土柱在水平载荷作用下的累积滞回耗能问题，采用等价滞回圈数的概念分析了钢管混凝土的低周疲劳损伤问题，并进一步考虑了地震作用下的损伤情况，在双参数累积损伤模型的基础上，根据实验研究结果，通过修改耗能因子，使其损伤模型适用于钢管混凝土结构，为进一步深入地研究钢管混凝土的地震损伤提供了基础．
In this paper, the dissipated hysteric energy of concrete filled steeltube (CFST) column is investigated in shear loading and the low cycle fatiguedamage is studied by means of equivalent number of cycle, which includes structural seismic damage. On the basis of the testing results and the double paramentersdamage model, a modification of dissipated energy factor was made for the modelused in CFST structure, which provided a base for the seismic damage calculation of CFST structures.
