摘　　要：为研究装配式加强型节点的力学性能与抗震性能,文中设计了装配式加腋加强型中柱节点,对6个不同构件尺寸的中柱节点进行低周往复循环加载的拟静力数值分析,分析结果表明,装配式加腋加强型节点比同尺寸全焊节点有更好的耗能能力;比无腋板节点有更高的承载力,经适当调整后,耗能能力可大于无腋板节点;节点腋板长度、腹板连接位置和柱壁厚度对节点抗震性能与承载力有较大影响,节点设计时应适当考虑方钢管柱强度与腹板连接位置。In order to study the mechanical property and earthquake resistant behavior of assembled reinforced joints,the assembled axle reinforced middle column joints were designed.The quasi-static analysis of 6 middle column joints with different member sizes under low-cycle reset load is carried out.The analysis results show that the assembled axle reinforced joint has better energy consumption capacity than the full-welded joint of the same size;It has higher bearing capacity than the joints without axillary plate.Its energy consumption capacity can be greater than that without axillary plate joint after proper adjustment;The axillary plate length,web connection position and column wall thickness of the joint have greater influence on the earthquake resistant behavior and bearing capacity of the joint.The strength of square steel tube column and the location of web connection should be considered appropriately in joint design.
