本文选取了适于混凝土材料的非线性本构关系，考虑了钢筋与混凝土之间的粘结滑移及混凝土开裂后骨料的咬合力作用，编制了计算机程序。该程序可用于分析钢筋混凝土构件在多种荷载工况下，由加荷、开裂直到破坏的全过程分析。为节省计算时间，本文提出对三角形混凝土元隔单元进行强度判断的方法。程序中，还对钢筋与混凝土之间的粘结滑移关系及不同的裂缝模型对计算结果的影响进行了分析；应用该程序计算了三十一根试验梁，结果是比较满意的。
This paper selects the nonlinear constitutive relation for concrete materials, considers the bond-slip between reinforcement and concrete, and the bite force of aggregates after concrete cracking, and compiles a computer program. This program can be used to analyze the full-process analysis of reinforced concrete members under various load conditions from loading, cracking, and failure. In order to save computing time, this paper proposes a method to determine the strength of triangle concrete element. In the program, the bond-slip relationship between steel bars and concrete and the effect of different crack models on the calculation results were analyzed. Using this program, thirty-one test beams were calculated and the results were satisfactory.
