摘要
本文采用协调桁架模型与钢筋砼受剪单元的修改受压屈服理论，推导了钢筋砼梁、框架柱及偏心受拉构件的抗剪承载力统一理论计算式．该式由三部分组成，即箍筋的抗剪、剪压区砼的抗剪和砼拉应力作用的抗剪．计算式与５７个试件的实测值对比，表明具有较高精度．
A general shear strength formula has been derived by using compatibility truss model and modified compression field theory,which can treat beams,colunms and members subjected to eccentric tension.The shear strength is composed of three parts which are contributed by stirrup,concrete of shear compression area and tension stress of concrete.Testing results of 57 members are analyzed,and the calculated values are in good agreement with the data.
