摘要
本文在理论分析和试验结果的基础上，针对钢管混凝土结构受力特点，对混凝土边界面模型进行了研究，它不仅较全面地反映了材料在三向复杂应力状态下的性能，准确可靠，而且在非线性有限元计算中简单可行。
Based on theoretical analyses and the results of tests, the paper studies concretebounding surface constitutive relationships. The behavior of the material under multi-axial loadingis taken into account completely and accurately in the relationships. It is shown that therelationships are simple and effective in nonlinear finite element analysis.
