摘要
目前钢结构在电厂工程中运用广泛,钢结构梁柱节点的设计又是钢结构工程设计中的重点与难点,钢结构梁柱节点根据梁柱夹角变形程度可以分为刚性节点、半刚性节点和铰接节点,在实际工程中,完全的刚性节点和铰接节点是不存在的,大部分节点属于半刚性节点。选取半刚性节点中采用短T型钢连接的节点形式为研究对象,对该节点进行国内外研究成果的总结归纳。依据滞回曲线和骨架曲线,得到该类节点的承载能力、耗能能力等抗震性能指标,揭示该类节点的受力规律,并以一实际框架为例,验证该类节点的半刚性性能,为该类节点在实际工程中的应用提供参考。
At present,steel structure is widely used in civil engineering of the power plant.The design of steel beam-column connections is the key and difficult point in steel structure engineering design.Steel beam-column connections can be divided into rigid connections and semi-rigid connections and hinged connections according to the degree of change of the angle between beams and columns.Completely rigid connections and hinged connections do not exist,most of the connections are semi-rigid connections.This paper selects the form of the steel connections with T-stubs as the research object,and summarizes the research results of this form at home and abroad.Seismic behaviors such as bearing capacity,dissipative capacity can be derived from the hysteretic curves and skeleton curves which can be used for reference in the connection design and practical application.
