摘　　要：钢管混凝土是在钢管内填充混凝土组成的一种组合材料。参照 M.D.Kotsovos和 J.B.Newman提出的混凝土三向本构关系和钢管混凝土中混凝土的单向本构关系模型，推导出一种适合于钢管混凝土三维双重非线性分析的混凝土三向本构关系，并通过编制的有限元程序计算算例，验证了所推导的钢管混凝土中混凝土的三向本构关系的正确性。Concrete filled steel tubes can be considered as a kind of composite material. This paper deduces three dimensional stress strain relations of concrete in concrete filled steel tubes on the basis of three dimensional stress strain relations of concrete deduced by M.D.Kotsovos and J.B.Newman and one way stress strain relations of concrete in concrete filled steel tubes. Three dimensional stress strain relations of concrete in concrete filled steel tubes is proved by an example analyzed by finite element program, and it can be used for three dimentional dual non linear analysis.
