［摘要］采用有限元分析程序ANSYS对一双轴对称的剪力墙结构建立一两层1/4平面的模型，分析竖向荷载作用下楼板的内力，并与基于传统方法的PMCAD的计算结果对比。指出由于不能考虑支承的竖向位移，传统方法计算的楼板弯矩比有限元方法的结果偏大或者偏小，甚至反号，从而导致不适当的钢筋配置，既浪费又不安全。

Abstract:A reduced model of a reinforced concrete shear wall structure was built in ANSYS and the internal forces of the slabs were obtained under vertical loads by static analysis. The results were compared with those calculated by PMCAD, which is based on a traditional simplified analysis method. Since the vertical displacements of the slab supports can not be considered in the traditional method, the moments computed by PMCAD are larger or smaller than those analyzed by ANSYS, and even their signs are different. This leads to the improper rebar configuration, which is both unsafe and wasteful.
