摘　　要：采用非线性有限元分析方法研究组合楼板和普通混凝土楼板在循环荷载作用下的受力性能,并由此得到两类楼板的滞回曲线、骨架曲线及应力应变分布规律。计算结果表明,采用可靠构造措施的压型钢板和混凝土组合作用明显,在不失较高承载力的同时,组合楼板仍具有良好的抗震性能。The mechanical behavior of composite slabs and concrete slabs under cyclic load is studied through nonlinear finite element method.At the same time,the hysteresis loop,skeleton curve and distribution of stress and strain are obtained.The analytical results indicate that with the reliable construction measures,the composite effects of profiled sheet and concrete are obvious,the composite slabs have good aseismic performances,while not lose high load bearing capacity.
