摘    要:本文针对在钢筋混凝土结构有限元分析过程中,混凝土和钢筋的本构关系复杂而导致单元刚度计算困难这一问题,提出了用三次多项式分段模拟混凝土和钢筋本构关系的方法。文中叙述了混凝土和钢筋的本构关系及模拟方法,分析了混凝土、钢筋的模拟曲线与原曲线之间的相对面积误差。

关 键 词:钢筋混凝土结构  非线性  本构关系

Abstract:In the finite element analysis of reinforced concrete structures, the complicity of constitutive laws of concrete and reinforcement makes the computation of element stiffness matrix very difficult. The paper presents a simulating method of concrete and reinforcement constitutive laws with the cubic polynomial functions in each segment. The method makes the simulating function approach the original function, and the computation of element stiffness matrix clear, readable and easy. The paper also gives out the constitutive laws and simulating function of concrete and reinforcement under the axial tension and compression, as well as the relative area error of concrete and reinforcement between the original function and the simulating function.
Keywords:reinforced concrete structures  non - linear  constitutive laws
