摘　　要：对受均布荷载作用的简支部分剪力连接钢－砼组合梁的滑移应变和滑移的分布规律进行了理论分析，得出部分剪力连接钢－砼组合梁的剪力连接程度系数与滑移应变和滑移的关系．分析了考虑滑移效应的梁的曲率及其与剪力连接程度系数之间的关系．结果与结构在弹性阶段的实验相当吻合，对组合梁挠度的精确计算有指导意义．This paper analyzes the distributions of the slip strain and the slip of the simply supported steel-concrete composite beams with partial shear connection under uniformly distributed load, derives relationships between shear connection degree index and the slip strain or the slip of the steel-concrete composite beams. The curvature is obtained with considering slips. The results agree well with exper- iments of this kind of structures in the elastic stage. The method can be used to calculate accurately the deformation of composite beams.
