摘　　要：利用ANSYS模拟钢筋混凝土2根简支梁破坏过程,并利用ANSYS的后处理程序绘出荷载-位移和弯矩-位移曲线,根据荷载-位移和弯矩-位移曲线分析简支梁的不同的破坏形式,给出极限弯矩和抗剪承载力,与混凝土结构设计规范(GB50010-2002)计算的结果比较,分析了2种计算结果差异的原因.The failure process of two reinforcement concrete beams was simulated by ANSYS software. Deflection- Load and moment-load curves were also obtained by ANSYS postprocessor. According to the curves, the types of failure were given. The extreme moment and shear force were compared with the results calculated by the teaching material. Compared with concrete structure design standard , the reason for difference between two methods was analyzed.
