摘　　要：基于不同构造形式框支网格式轻质墙板低周反复荷载试验,通过不同损伤性能评估模型的比较,提出适合该类结构的损伤模型.采用OpenSees准确模拟结构的力学性能,得出相应力学参数,验证损伤模型的合理性.给出与框支网格式轻质墙板结构各累积损伤阶段对应的损伤指数取值范围.基于试验,分阶段对结构累积损伤性能进行描述,并采用ANSYS模拟累积损伤发展阶段,提出框支网格式轻质墙板结构后期修复建议.This study focused on the behaviour of the frame-supported grid light-weight slabs （FSGL slab） with different forms under low-cycle reversed loadings. Compared with the existing evaluation mod- els showing different damage performances, a damage model was proposed for the FSGL slab system. The mechanical properties of the FSGL slab system were investigated by OpenSees simulation, and the corre- sponding mechanical parameters were obtained to verify the proposed damage model. Meanwhile, the range of damage index value corresponding to the cumulative damage stage was provided. Furthermore, on the basis of test results, the cumulative damage of FSGL slab system at each stage was described by AN- SYS software. Finally, the post-repair recommendations for FSGL slab system were given.
