仿真计算中钢筋混凝土材料的等效模量

Equivalent moduli of reinforced concrete in simulating analysis

将复合材料细观力学的理论应用于钢筋混凝土结构仿真分析中,提出了钢筋混凝土材料有限元计算的新方法.在Y.H.Zhao和G.J.Weng[1,2]所建立的纤维增强复合材料的等效模量公式的基础上,经过适当的修正确定了钢筋混凝土材料的平均等效模量的简化公式 应用等效模量使有限元分析建模简单、精度高,特别适用于大体积和复杂结构的仿真分析 为钢筋混凝土这种被普遍认为难以进行高精度仿真的结构材料的分析计算开辟了新途径.

A new theoretical method of finite element is proposed by applying the theory of Micro Mechanic of Composites in the analysis of reinforced concrete based on the equations of equivalent moduli of fiberreinforced composites derived by Y.H. Zhao and G.J. Weng. Some modification are made for the reinforced concrete and the equations of equivalent elastic moduli are set up. The simulating calculation of the structures of reinforced concrete, especially those with huge volume and complicated geometry, becomes easier by using the equivalent moduli.The multiple advantages of precision and the effectiveness are proved in the comparison of the result with traditional simulation calculations.
