| 摘 要： | 用剪压区复合应力状态下的强度准则推导了钢筋混凝土梁斜截面抗剪承载力的表达式。用所收集到的159根受单点或两点集中荷载作用、8点、12点及均布荷载作用和多点不对称集中荷载作用的梁的试验数据作了验证,表明了良好的吻合性。

| Abstract: | According to the combined compression-shear strength criterion of concrete in reiforced concrete beams,a formula for computing shear capacity of beams is deduced. The equilibrium condition is used,the compatibility condition and other added conditions are discovered by test. The calculated results show good agreement with experimental data which include 159 simply-supported beams acted by 1 or 2 points concentrated simmetrical load,uniform contributed load and multipoint concentrated asymmetrical load. |
