钢筋混凝土井字梁被广泛应用于各类建筑中。由于钢筋混凝土材料非线性的性质，通用结构设计软件PKPM 不能很精确地得到荷载作用下井字梁结构的竖向挠度。本文以 PKPM 软件为主，针对某一井字梁工程实例，采用大型通用有限元软件辅助 PKPM 软件进行了非线性分析。本工程实例解决了由于 PKPM 软件本身缺点而引起的钢筋混凝土井字梁结构竖向挠度超限的问题，节约了材料，取得了一定的经济效益。

Reinforced concrete grillage beam is widely used in various types of buildings. Because of nonlinearity of reinforced concrete materials, the general structure design PKPM software can't exactly figure out the vertical deflection of grillage beam structure under loading. Here, it takes a case of grillage beam engineering as example, the nonlinear analysis is carried on by large-scale general finite software assisted PKPM software. The engineering example can solve the vertical deflection transfinite question of reinforced concrete grillage beam structure cauced by disadvantage of PKPM software, and the method can save the material and also achieve some economic benefits.
