摘　　要：为建立适用于圆钢管构件的地震损伤模型,基于Park-Ang双参数地震损伤模型,通过修正组合系数,研究了组合系数与构件参数间的变化关系,并根据圆钢管构件性能特征点提出了圆钢管构件在不同破坏状态下的损伤性能水准划分标准。In order to establish the seismic damage model suitable for circular steel tube members,based on the Park-Ang two-parameter seismic damage model,the relationship between the combination coefficient and the component parameters is studied by modifying the combination coefficient.According to the performance characteristic points of circular steel tube members,the damage performance level division criteria of circular steel tube members under different failure states are proposed.
