| 摘 要： | 钢-混凝土组合梁翼板剪力滞效应对组合梁截面应力和变形产生重要影响。基于组合梁弹性理论分析模型，忽略界面滑移效应，推导了简支和悬臂组合梁在均布和集中荷载作用下的应力和变形解析解。通过引入翼板有效宽度和截面有效刚度的两种简化设计方法分别考虑翼板剪力滞效应对组合梁截面应力和变形的影响。用该文提出的简化设计方法计算考虑剪力滞效...

| Abstract: | Shear lag effect has significant effect on stress and deflection of composite beams.According to the elastic analytical model of composite beams,stress and deflection analytical solutions for the cases of simply supported composite beams and cantilever composite beam under uniform distribution load and concentrated load are derived by ignoring slip effect in the interface.By introducing effective flange width and effective sectional rigidity,practical design methods for considering shear lag effect of compo... |
