| 摘 要： | 本文根据钢筋混凝土结构构件力学性能,运用有限元的基本思想,将钢筋混凝土微元体等效成平面桁架单元对钢筋混凝土结构进行非线性分析。理论分析和计算结果表明,用此模型对钢筋混凝土结构构件平面应力问题进行分析是可行的,它能满足工程精度要求,而且在加载过程中可以很容易追踪裂缝开展顺序、裂缝位置和开裂程度,同时使计算模型简单化。

| Abstract: | Based on the mechanical performance of reinforced concrete structure members and the thought of finite element method, the reinforced concrete structures are nonlinearly analyzed by using the equivalent plane truss element to replace the micro element in this paper. Theoretical analysis and numerical examples showed that this model is feasible to analyze planar stress problems of reinforced concrete structures. It can satisfy the requirements of engineering precision. The appearing sequence, location and degree of cracks of the structures under loads can be easily traced. In the meantime, the mechanical calculation model of the structure can also be simplified. |
