摘    要:基于Gjelsvik组合梁滑移模型中引入描述组合梁翼板横向非均匀分布的纵向位移翘曲函数,建立一个能够同时考虑界面滑移和翼板剪力滞双重效应的钢-混凝土组合梁模型,并推导了简支组合梁在均布荷载和悬臂梁在梁端集中荷载作用下的解析解。采用有限元方法验证了理论模型和解析解的正确性和适用性。算例分析表明,组合梁的剪滞效应和界面滑移...

关 键 词:钢-混凝土组合梁  滑移效应  剪力滞效应  有效宽度系数  解析解

Abstract:An analytical model is proposed for steel-concrete composite beams accounting for not only the slip between the steel beam and concrete slab but also the shear lag effect in the concrete slab.In order to considering the shear lag effect,a warping shape function accounting for the non-uniform transverse distribution of longitudinal displacements in the concrete flange is introduced into Gjelsvik's model.Then analytical solutions for the cases of simply supported composite beam under uniform distribution load...
Keywords:steel-concrete composite beam  slip effect  shear lag effect  effective width coefficient  analytical solution
