【摘要】 钢结构梁柱连接节点是保证梁和柱协同工作的关键部件,其性能直接影响结构的刚度、稳定性和承载能力.对钢结构梁柱节点应用及发展历史进行回顾,对近年来节点抗震性能的研究进展及其构造措施的改进进行总结.发现目前梁柱连接节点的耗能能力和塑性变形多是由梁端形成的塑性铰提供;尽管这些节点在实验中表现出优越的抗震性能,但实际工程这些节点若受到损坏,修复相对困难且费用较高.为便于震后修复,基于控制思想提出了带有耗能元件的梁柱节点构造.然而目前该技术尚存在一些不足,需要进一步研究.更多还原

【Abstract】 Beam-to-column connections are the key parts for guaranteeing beams and columns to work together.Their performance can affect significantly the stiffness,stability and bearing capacity of structures.This paper looked back the history of application and development of the beam-to-column joints,and summarized the seismic performance research and some improvements of connection details recently.It was found that the energy dissipation and plastic rotation of the common joints are provided by the plastic hinges which are formed in the beams.Although the joints display excellent seismic performance in laboratory,the damaged joints in practice will be repaired difficultly and costly.Some innovative connections,based on the intelligent control concept,could not only provide good seismic performance but could also be easily repaired after a heavy earthquake.However,the technology of the connections is not enough to use in practice and the further research need carry out.更多还原
