摘    要:本文对钢─混凝土简支组合梁交接面相对滑移引起的附加变形进行了理论分析。在建立相对滑移微分方程的基础上,得到了不同荷载情况下钢─混凝土组合梁因滑移效应引起的附加变形计算公式。通过对理论公式的简化和修正,得到了考虑滑移效应和部分剪力连接组合梁挠度计算的一般公式。本文公式简单、实用,并且与实验结果吻合良好。

关 键 词:钢─混凝土组合梁,滑移效应,不完全剪力连接,变形计算,一般公式

Abstract:Theoretical analysis and derivation are conducted for the effect of slip on the deformation of simply supported composite steelconcrete beams. On the basis of established differential equation of relative slip, formulae predicting the deflection due to the effect of slip are proposed for different loading cases. Revised and simplified, a general formula predicting the deflection of simply supported composite steelconcrete beams is suggested, with the consideration of effect of slip and incomplete shear connection. The proposed formula is well coincided with the experimental results.
Keywords:composite steel-concrete beams  effect of slip  incomplete shear connection  prediction of deflection  general formula
