压型钢板—混凝土组合板的组合效应分析

Analysis on composite action of composite slabs constructed with profiled sheet and concrete

压型钢板-混凝土组合板构件中,压型钢板和混凝土的组合效应体现了两者之间共同工作的程度,也体现了构件的抗剪强度。为了研究工程中各种组合板的组合效应,提出了组合效应系数的概念,并通过对试验资料的分析,提出组合效应系数的计算式,根据计算结果初步判断组合板构件的破坏形态。现在用两个试验对算式进行验证,结果基本相符。

Composite action shows the cooperation between the profiled sheet and concrete in the composite slabs. To study composite slabs＇ composite action, this paper gives a composite action coefficient, and presents formulae to calculate it based on the analysis of experimental researches. The model of failure of composite slabs can be deduced by the composite action coefficient. The paper also proves the formulae with two tests, and the result basically agrees.
