| 摘 要： | 在21根双向受弯无腹筋钢砼矩形截面梁的试验研究基础上，推导了无腹筋双弯梁斜截面受到承载力的计算表达式，采用将箍筋与砼分开单独考虑的离散化原则，进一步得出有腹筋双向受弯梁斜截面受剪承载力的计算表达式，11根有腹筋梁的理论计算与试验实测结果平均比值为0．93。

| Abstract: | Based on experimental research of 21 reinforced concrete beams without web reinforcement under biaxial bending,the expressions for calculating shear capacity of concrete beam without web reinforcement are deduced.Considering the contribution of concrete and hoop seperately,the expressions for calculating shear capacity of reinforced concrete beams are obtained.The mean ratio of theoretical calculation to test results is 0.93. |
