摘　　要：以弹性理论为基础,推导了均布荷载作用下压型钢板-混凝土组合楼板的挠曲微分方程,分析得到了考虑滑移影响的压型钢板-混凝土组合楼板挠度计算公式,提出了考虑滑移效应影响的压型钢板-混凝土组合楼板的刚度折减系数,分析了各设计参数对刚度折减系数的影响规律,并进行了18块足尺寸压型钢板-混凝土组合楼板的试验验证工作。分析结果表明,挠度的理论计算值与试验实测值之比的平均值为0.97,变异系数为0.14,两者吻合较好。The flexure differential equation of composite slabs with profiled steel sheeting under uniformly distributed load is deduced,and the deflection formula considering slip effect is obtained based on the elastic theory.The reduction coefficient of rigidity is proposed and the influence law of the design parameters on the reduction coefficient of rigidity is analyzed.Finally,the experimental verification of 18 composite slabs with profiled steel sheeting is conducted.The results show that the calculation value is consistent with the theoretical value of deflection,the average value of the ratios is 0.97,and the variation coefficient is 0.14.
