摘要
某工程两栋主楼之间采用大跨度桁架钢结构连廊连接,跨度约55米,连接位置的钢桁架梁与框架主梁斜交,形成了受力复杂的钢管混凝土柱-钢梁空间节点。本文在选择合理的钢材和混凝土的本构关系模型的基础上,利用通用有限元软件ABAQUS对上述节点进行抗震设计分析,以此得到满足设计要求的材料强度。本文的分析方法可为工程设计提供参考。
Some complex concrete - filled steel tubular column - steel beam space joints were made with the fact that there was a steel truss vestibule with about 55 meters span between the two towers of a building and the steel trusses intersected the frame beams diagonally. Based on rational constitutive model of steel and concrete, the seismic designing of the joints were analyzed by the ABAQUS software and the material strength to meet the design requirements were gained. The analytic method in this paper may be referred in engineering.
