摘要
根据混凝土结构的基本力学性能和有限单元法及非线性分析的基本方法，在用有限元法分析钢筋混凝土结构时，采用平面桁架单元对混凝土结构进行单元划分。理论分析和计算结果表明，采用平面桁架单元对混凝土结构平面应力问题进行有限元非线性分析是可行的，它能满足工程精度要求，能够很容易追踪混凝土裂缝开展的位置、顺序、宽度及深度，同时也简化了结构的计算模型。
Based on the mechanics performance of concrete structures, the finite element method and the method of non-linear analysis, in this paper, in order to analyze the reinforced concrete structures, plane truss elements are used, Theoretical analysis and numerical examples show that it is feasible to analyze plane stress problems of concrete structures by this method, It can satisfy the requirements of engineering precision. The appearing sequence, the location and the degree of cracks of the structures under loads can be easily traced, In the mean time, the mechanics calculation model of the structure can be simplified,
