摘　　要：压型钢板—混凝土组合板两材料之间的接触和相关力学性能较为复杂。为了表明一种闭口型压型钢板—混凝土组合板的承载性能,采用非线性有限元分析软件ABAQUS对混凝土强度、压型钢板屈服强度、纵向剪切强度给予整体承载性能的影响进行了参数分析。并建议采用简化纵向剪切强度—水平滑移关系的有限元建模方法,而其计算结果与力平衡法而得到的有限元分析结果和欧洲规范4设计计算结果进行了对比。结果表明,对组合板的承载性能给予最大影响的因素之一为纵向剪切强度。并且建议的修正有限元模型结果具有良好的准确性。An interaction between the concrete slab and the steel deck is very complex.To verify the load carrying capacity and the interaction,numerical studies,which include three parameters such as horizontal shear bond,strength of concrete and steel deck,and shear span,were carried out.Moreover,simplified horizontal shear bond model of FEA was suggested.Its results are compared with each tested data and results by Eurocode 4.As a result,the simplified horizontal shear bond models are well matched with tested results and other methods above.
