摘　　要：近年来,钢-混凝土组合梁在桥梁中的应用越来越广泛。但是长期以来,钢-混凝土组合梁的计算以换算截面法为主,均未考虑滑移这一不利因素。该文总结了聂建国等提出的考虑滑移效应的钢-混凝土组合梁变形和强度计算方法,并介绍了其基本推导过程。In recent years,the steel – concrete combined beam is widely used in bridges.However,the calculation of steel –concrete combined beam is mainly by section conversion method for a long time,and this unfavorable factor of slippage has not considered.The article sums up the calculation methods of steel – concrete combined beam deformation and strength considering the slippage effect,and introduces its basic derivation process.
