摘要: 钢梁和混凝土之间的相对滑移效应使钢-混凝土组合梁变形增大。基于弹性理论,在考虑剪切滑移效应情况 下,建立了钢-混凝土组合梁刚度计算的解析方法,计算组合梁任意截面的等效刚度。研究表明:截面等效刚度受 到拴钉剪切刚度、剪切滑移的影响;在拴钉间距较大时,组合梁刚度和折减刚度之间有不可忽略的差值。按此方法 算得的组合梁挠度值与试验结果吻合较好。

Abstract: The slip effect between steel and concrete in composite beam has an evident contribution to the deformation of the beam. An analytic method was proposed on the basis of elastic theory,considering shearing slip,to calculate the equivalent rigidity for composite beam with arbitrary cross-section. The results show the rules of equivalent rigidity changing from shearing slip and rigidity effects; and the difference value of the rigidity and reduced rigidity when the stud spacing is huge. The composite beam deflection caculated by this method has a good agreement with those obtained from experiment.

Key words: steel-concrete composite beam, shearing slip, equivalent rigidity, analytic solution
