摘　　要：通过有限元数值模拟,规范公式计算两种方法分别研究主次梁斜交时(次梁为斜梁)次梁箍筋布置方式对其抗剪承载力的影响,并将两者结果进行对比分析,结果表明:有限元软件可以较好地模拟钢筋混凝土梁的破坏过程,次梁箍筋采用文中两种方式布置对其抗剪承载力影响不大,均可根据钢筋混凝土结构设计规范公式计算其抗剪承载力,其结果偏于安全。The effects of stirrup layout on RCbeam shear strength were studied through FEM analysis and standardized formula.The results of comparative analysis show that the finite element software can simulate the destruction process of RC-beam well.And the stirrup layout has little effect on RC beam shear strength which can be calculated by reinforced concrete specification.
