摘　　要：通过对钢—混组合梁截面上弯曲应变图形的分解,将组合梁界面处的连接按弹性连接考虑,按混凝土板与剪力连接件回弹力相等的原理建立滑移量计算方程,推导了滑移应变计算通用公式,并给出了求解的边界条件。Through the division of the bending strain on the section of the steel-concrete composite beam.Considering the connection at the interface of composite beam as elastic connection,the calculation formula of slip is established according to the principle that the rebound force of concrete slab and shear connector is equal.The general formula of slip strain calculation is derived,and the boundary conditions are given.

关 键 词：钢—混组合梁 界面滑移应变 边界条件
