摘　　要：为了系统了解SRC组合梁构件剪切性能,采用自行编制的针对组合梁构件的非线性有限元分析程序SRCBNP,模拟了-1系列试验构件,得到了相应的荷载位移曲线和B1-1.5p试件裂缝开展过程等。与试验结果对比,表明有限元分析结果与试验实测结果吻合较好。To investigate the behavior of steel-reinforced concrete composite beam with shear systematically, the nonlinear finite element program named SRCBNP was adopted. The specimens from the test were selected as the subjects to be analyzed, forming and development of crack and crushing of concrete in B1 - 1.5p were simulated, their load-deflection behaviors was derived. The results showed them agree well with the test.
