摘要
中空夹层钢管混凝土柱-钢梁采用穿心高强螺栓-外伸端板构成的组合节点建立有限元模型。分析了模型在梁端单调加载下的应力分布规律及柱轴压比、方钢管壁厚对节点力学性能的影响。
The finite element model of hollow sandwich concrete-filled double skin steel tubular is established using the combined joint of high strength bolt-end plate joint and axial compression ratio.The stress distribution law of the model under monotonic loading at the beam end,the axial compression ratio of the column and the influence of the wall thickness of the square steel tube on the mechanical properties of the joints are analyzed.
