摘要
考虑到剪力滞效应的影响,在钢-混凝土组合梁设计分析中,常采用翼缘有效宽度的概念计算组合结构的应力和变形。针对简支组合梁,采用非线性有限元方法结合试验比较有效宽度在承载极限状态下及弹性状态下的区别,分析宽跨比、栓钉布置、加载形式等主要因素对有效宽度的影响程度,提出组合梁极限状态下有效宽度取值及不同栓钉布置情况下的取值方法,可供工程设计人员参考。
Due to the shear lag effect, in the design of steel-concrete composite beams, the effective flange width concept is used to analyze the defections and stresses of beams. As to the composite beams, the nonlinear finite element method combined with the experiment is used to compare differences of the effective width of composite beams in the elastic stage and plastic stage, and also to analyze the effects of the width-span rate, layout of peg and load operation on effective width. The paper finally presents the effective estimation of composite beams in the elastic stage and different layout of peg, which ean be of some help to the engineering designers.
