考虑密肋板双向受力的相关性和钢筋混凝土的非线性特性 ,采用刚度等效的正交各向异性板单元模型求解密肋板在竖向荷载下的变形 ,编制了程序WAF ;并用试验结果验证其正确性 ,证明这一方法准确易行 ,适于工程应用
Considering the correlation between the bi-directional stress of the multi-ribbed stiffeners and the non-linearity of the reinforced concrete, the equivalent anisotropy plate element model was used to solve the deformation of the dense rib under the vertical load. The program WAF was programmed. The results verify its correctness and prove that this method is accurate and feasible and suitable for engineering application
