摘要
腹板双角钢连接作为梁柱节点的一种常用连接方式大量使用于钢结构工程中,其节点的受力性能和破坏方式与钢框架的抗倒塌性能密切相关.采用显式动力准静态法分析了腹板双角钢连接梁柱子结构在大变形下的抗力机制转换及破坏模式,并通过试验结果进行了分析验证.通过对影响钢框架梁柱子结构抗倒塌性能的主要因素(梁跨高比、连接角钢厚度及节点螺栓布置)进行参数分析,获得了一些有价值的结论,为同类连接形式的钢框架结构抗倒塌分析和设计提供参考.
Double web angles connection is the common for beam-column joints in the steel structure, and the mechanical performance and failure mode of the joint are related to the collapse resistance of steel frame closely. The explicit dynamic quasi-static method is used to analyze the mechanical transformation of resistance and the failure mode of beam-column substructure with double web angles connection under large deformation. The calculation results are validated through the experimental data. The main factors（span-to-depth ratio of beam, thickness of angles and bolts arrangement in joint） are analyzed, which may affect the collapse resistance for beam-column substructure of steel frame, and some valuable conclusions are drawn, which provide reference on collapse resistance analysis and design for this kind of connection form of steel frame.
