摘    要:组合空腹板中剪力键、钢肋及混凝土板连接节点是结构的关键节点,本文建立了基于空间壳单元的有限元模型,对这类节点进行了理论分析,得到了节点区域的应力分布规律和变形特点。研究表明,节点区域内各构件的接触面附近,存在较大的应力集中现象。指出了应力集中的原因及解决措施。

关 键 词:组合结构  组合空腹梁  节点  应力分布  剪力键

Abstract:The conjunction node of shear block of steel tube, steel fib and concrete slab in the composite open- web plate is the pivotal node. The theoretical analysis of these nodes is built based on the finite element method of spatial shell elements in the paper. The rule of the stress distribution and the characteristics of distortion in the area of node are acquired. The research shows that the stress concentration is large near the interface of each component in the area of node. The reasons and resolvents of stress concentration are given in the paper.
Keywords:composite structure  composite open- web beam  nodes  stress distributing  shear block
