摘要
本文在阐述损伤值概念的基础上，提出了一种适用于钢筋混凝土（简称ＲＣ）和劲性钢筋混凝土（简称ＳＲＣ）构件的累积损伤模型。该模型综合考虑了大变形幅值以及荷载循环所引起的损伤，比较准确地定量描述了构件在低周反复荷载作用下的损伤过程。
A model which describes the cumulative damage in reinforced concrete(RC ) and steel reinforced concrete(SRC)members subjected to cyclic load is given in this paper. As revealed, the model reflects synthetically the damage caused by large deformation and cyclic loading and it could give a quantitative description of the members′ damaging process.
