摘要: 为了研究影响钢-混凝土组合框架中组合楼盖隔板性能的因素,以楼板厚度、框架侧 移刚度以及结构平面刚度布置为参数对钢框架中的组合楼盖进行了弹性有限元分析. 分析结果表明,除长宽比外,组合楼盖的隔板性能还与其面内刚度以及支撑体系的特 性有关. 根据分析结果提出了组合楼盖隔板性能的评价方法,并与试验结果进行了验 证. 该方法可以为工程实践中评价组合楼盖的隔板性能作参考.

Abstract: Elastic finite element analyses are conducted to investigate the factors influencing the membrane behavior of steel-concrete composite floor slabs. Parameters include concrete slab thickness, lateral stiffness of frames and the arrangement of the lateral stiffness system. The results show that the membrane behavior of composite floor slabs is influenced not also by the length-width ratio but also its in-plane stiffness and the lateral system. A new method of evaluating the membrane behavior of composite floor slabs is established based on the parameter studies. The method is proved to be valid by comparison with the test results. The method mentioned in this paper provides a useful tool in composite floor slab design.
