摘　　要：为了系统了解SRC组合梁构件剪切性能,针对文献[1]中组合梁的非线性有限元计算结果加以分析,得到了相应的破坏模式。与试验结果进行对比表明,有限元分析结果与试验实测结果吻合较好。并进一步分析了剪跨比λ和RC强度对构件性能的影响,为相关规程规范的修订提供一定的理论依据。To investigate the behavior of Steel-Reinforced Concrete composite beam with shear systematically, the results from the nonlinear finite element program in then rcfercnce [ 1 ] was utihzed to analyze, the failure modes were derived. The results showed them agree well with the test. Moreover the shear-span ratios and RC strength were analyzed, the study results provide the theoretical basis for relative specification and code.
