装配式钢结构连接节点抗震性能研究

Research on Seismic Performance of Fabricated Steel Structure Joints

文中以沿海地区某高层办公楼项目为例,对装配式钢结构不同连接方式进行结构抗震设计,并通过拉伸、扭转、剪切等不同荷载对4种不同连接节点进行抗震性能试验。结果显示,在拉伸荷载下,螺栓连接方式表现最佳,平均承载能力为120 kN,而在剪切荷载下,焊接连接和螺栓连接的平均承载能力较好,分别为70 kN和80 kN。根据数据分析初步推断,在该项目中,螺栓连接方式具有较高的适用性。

This paper takes a high-rise office building project in coastal area as an example to carry out seismic design of prefabricated steel structure with different connection modes,and carry out seismic performance test of four different connection nodes under different loads such as tensile,torsion and shear.The results show that the bolted connection performs best under tensile load,with an average load capacity of 120 kN,while the welded connection and bolted connection have a better average load capacity under shear load,with 70 kN and 80 kN respective-ly.According to the data analysis,the preliminary inference is that the bolted connection method may have high applicability in the project.
