摘要
采用拟静力试验方法对组合楼板在循环荷载作用下的受力性能进行试验研究,并由此得到组合楼板的滞回曲线、骨架曲线及荷载和挠度的特征值。试验结果表明,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。同时还对试验板件进行了非线性有限元分析,计算结果与试验数据吻合良好。
The mechanical behavior of composite slabs under cyclic load is studied through experiments. Based on the experiments, the hysteresis loop, skeleton curve and eigenvalues are obtained. The experimental results indicate that with the reliable construction measures, the composite slabs can have good seismic performances, without losing high load bearing capacity. In addition, the nonlinear finite element analysis has been done to the tested composite slabs and the analytical results agree well with those of the tests.
