摘要
利用桁架—拱模型对粘钢加固梁受剪机理进行分析,通过桁架模型和拱模型两者作用的叠加,推出粘钢加固受剪计算公式,指出该公式包含了配筋率、剪跨比、荷载作用形式、混凝土强度等受剪承载力影响因素。
It analyzes the shear mechanism of beams strengthened by bonded plate by using the truss-arch model.Through superposition of the truss-arch model and the arch model,it proposes the calculation formula of reinforcement and shear of bonding steels.It points out this formula contains the following influential factors of shear bearing： reinforcement ratio,shear span ratio,load action form,concrete strength,etc..
