我国规范中钢筋混凝土梁抗剪强度计算的演变

The development of shear strength calculating formulas of reinfoeced concrete beams in Chinese codes

从我国颁布的几本规范出发 ,探讨了钢筋混凝土一般受弯构件受均布荷载和集中荷载情况下的计算方法的演变 ,对一些公式和概念的修改作了适当的分析 ,总结出规范中未提到的影响因素。

The author analyses the differences of four Chinese codes, contrasts the reinforced concrete beams’ shear strength calculating formulas and their adapting conditions under the distributed load and the concentrated load, and explains some changes of them.
