摘要:
平齐端板连接是钢结构建筑中常用的梁柱节点连接方式之一，其节点的受力性能和破坏方式与钢框架结构的抗倒塌性能密切相关．针对平齐端板梁柱节点，采用备用荷载路径法，构建了基于悬链线机制的梁柱子结构模型，分析了钢框架结构在倒塌过程中梁机制与悬链线机制的转换机理．通过数值分析，并与相关试验数据进行验证，获得了梁跨高比和端板厚度等关键参数对钢框架梁柱子结构抗倒塌性能的影响规律，为同类连接方式的钢框架结构抗倒塌分析和设计提供参考．
Abstract:
Flush end plate connection is one of the common beam-column joints in the steel structure, and the mechanical performance and failure mode of the joint is related to the collapse resistance of steel frame closely. For flush end plate beam-column joints, the alternate load path method and beam-column substructure model based on catenary system are used to analyze the mechanical transformation between beam mechanism and catenary mechanism. Through numerical calculation, results are validated by the experimental data , and the influence law that the key parameters such as span-to-depth ratio of beam and the thickness of end plate affect the collapse resistance of beam-column substructure of steel frame is obtained, which provide reference on analysis and design of collapse resistance for this kind of connection form of steel frame.
