摘　　要：概述了钢筋混凝土结构有限元模型 ,针对有限元法模拟钢筋和混凝土两种介质交界面上不协调位移的不足之处 ,引入界面应力元法 ,分析了钢筋混凝土结构中界面问题的特点 ,提出了用界面应力元法模拟钢筋混凝土结构的建议 。A finite element model for analysis of steel-concrete structure is summarized. On the interface between the two different material there is incompatible displacement and finite element method has some difficulty in solving such a problem. So interface stress element method is introduced in order to solve the problem of incompatible displacement on the interface. Advice of interface stress element model of concrete structure is proposed.

关 键 词：钢筋混凝土结构 不连续介质 不协调位移 界面应力元法
