摘要
根据以前的研究提出最大薄膜应力法确定受水平约束的钢筋混凝土矩形板的极限承载力。对承受均布荷载的钢筋混凝土矩形板进行非线性有限元分析，分析了在水平受约束时板的薄膜效应，计算得到板的极限承载力，并与最大薄膜应力法求得的值进行比较，从而验证此方法的可行性。
Based on previous research maximum membrane force method used for determining the ultimate load of R. C rectangular slabs is put forward. The nonlinear finite element analysis of R. C rectangular slab under uniform load is carried out. Membrane effect of horizontal restrained slab is analyzed. The ultimate load of slab is calculated. Meanwhile, the results of calculation are compared with that obtained from maximum membrane force. Feasibility of this method is confirmed.
