【摘要】：为了研究多高层装配式钢框架结构体系方钢管柱采用钢板攻丝高强螺栓法兰连接节点的受力性能,进行了钢柱法兰连接节点的足尺模型静力和拟静力试验,分析了这类节点的承载力、失效模式以及在单向水平地震作用下的滞回性能。试验研究表明:试件在静力试验中表现出较强的承载能力,失效模式为短柱受压侧屈服;试件在拟静力试验中得到的滞回曲线比较饱满,试件延性较好,耗能性能优良,失效模式为短柱受压屈服。对这类钢柱法兰节点的受力性能进行了有限元数值模拟分析,数值模拟结果与试验结果吻合较好。通过比较节点刚接模型及栓接模型的有限元分析结果,从设计角度考虑,认为该类节点在实际工程应用中可视为等效刚性连接。
[Abstract]:In order to study the mechanical behavior of square steel pipe column with steel plate tapping high strength bolt flange connection in multi-high-rise fabricated steel frame structure system, the static and quasi-static tests of steel column flange connection joint were carried out on a full-scale model. The bearing capacity, failure mode and hysteretic behavior of this kind of joints under unidirectional horizontal earthquake are analyzed. The experimental results show that the specimen has a strong bearing capacity in static test, and the failure mode is short column under compression, and the hysteretic curve obtained in the pseudo-static test is full, the ductility of the specimen is better and the energy dissipation performance is good. The failure mode is short column compression yield. The finite element numerical simulation analysis of this kind of steel column flange joints is carried out, and the numerical simulation results are in good agreement with the experimental results. By comparing the results of finite element analysis between the rigid joint model and the bolted joint model, and from the point of view of design, it is considered that this kind of joint can be regarded as equivalent rigid connection in practical engineering application.
