摘要
为掌握实际工程中预选用的组合楼板的承载性能,以钢框架-混凝土组合楼板为研究对象,进行静力加载试验,并利用通用有限元软件ANSYS对试验中组合楼板进行承载模拟计算,结果表明组合楼板的槽钢和压型钢板发生塑性变形前的模拟计算结果与试验得到的荷载-挠度曲线吻合很好,基于简化的材料应力-应变关系的有限元计算模型可用于钢框架-组合楼板弹性范围内的承载性能分析中。
In order to grasp the bearing capacity of composite slabs which is used in actual demonstration project, the steel frame-concrete composite slabs is taken as research objective. This paper carries out static load test, and simulates the process by ANSYS software, The load-deflection curve which is obtained from simulation is good agreement with the test result, The finite element model which is based on a simplified material stressstrain relations can be used for analyzing the bearing capacity of the steel frame-concrete composite slabs.
