摘　　要：本文提出了一种模拟新老混凝土界面传力性能的粘结单元,编制了钢筋混凝土修补结构的非线性有限元程序,其数值计算结果与试验结果吻合较好。此粘结单元及其编制的程序比较合理可靠、方便快捷,能在试验的基础上,对钢筋混凝土修补结构的受力性能进行系统的数值分析研究。This paper proposed a bond element for simulating character of force transmission through the boundary between the fresh and older concrete, compiled a non-linear finite element program for the repaired steel bar concrete structure. The result of the numerical calculation is closely identical to that of experiment. The bond element and its program are comparatively reasonable, reliable, easy and fast, can be used for the systematic numerical analysis of stress in the repaired steel bar concrete structure.
