混凝土强度对钢框架梁柱节点承载性能的影响 - The strength influence of concrete slab on the performance of beam-to-column connection in steel frame structure

在多高层钢框架梁柱节点中,随着混凝土强度的提高,混凝土楼板的组合作用对节点力学性能的影响变得更加突出。本文结合混凝土本构模型,基于节点的有限元分析,讨论了混凝土强度对节点承载力性能的影响,并对比了组合节点有限元计算与钢结构规范组合梁计算结果。分析表明,提高混凝土强度会使节点的极限承载能力有一定提高,塑性段刚度增加,但对弹性受力影响较小。相比于现行规范组合梁公式计算值,有限元计算得出的组合节点承载力偏小。... Full description

1In the design of the steel frame connection, when the concrete strength is increased, the composite effect of the concrete slab on the mechanical performance of the connection becomes more and more significant. This paper applies a proper concrete constitutional model, and analyses the connection performance when the concrete strength varies. The finite element solutions were compared with the design method of the composite beam which is introduced by the code for design of steel structure. According to the analysis, the increase of the concrete strength brings moderate improvement to the ultimate loading capacity and plastic stiffness of the connection, and has less effect on the elastic stage. Compared with the results of the composite beam calculated according to the code, the loading capacity of which uses finite element method is smaller. the connection
