预应力混凝土叠合板的叠合面受力性能研究

Research on the Mechanical Behavior of Interface of Prestressed Concrete Composite Slabs

通过43块简支预应力混凝土叠合板的系统试验。探讨了预应力混凝土叠合板的叠合面在不同处理方式下的受力性能。在综合分析试验结果的基础上,提出了预应力混凝土叠合板在不同的叠合面处理方式下的叠合面受剪承载力计算公式和适用条件,计算结果与试验结果符合较好。文中还给出了叠合面粗糙度的明确定义和相应的施工方法。

Through the systematic experiments of 43 simply supported prestressed concrete composite slabs, the mechanical behavior of the interface of prestressed concrete composite slabs in different handling method for the interface is studied. Based on the comprehensive analysis of the experimental results ,the formulae of calculation for the interface shear capacity of prestressed concrete composite slabs in different handling method for the interface and the corresponding conditions of application are presented. The calculating results agree well with the experimental results. Furthermore, the definition about the roughness of the interface and the corresponding construction method are also proposed.
