摘要
介绍了一种防屈曲支撑连接段整体失稳的破坏模式,回顾并比较了现有的几种稳定设计方法,并针对目前存在的不足,建议在未来的设计中应考虑内芯与约束单元的相互作用机制及约束单元的弯矩传递机制等对防屈曲支撑连接段稳定性能的影响。
This paper introduces an overall instability mode of the buckling-restrained brace connections,and reviews and compares several existing stability design formulae about this issue.It is suggested that the moment transfer capacity at the restraining member or the interaction mechanism between the restrainer and the core should be taken into account in the future design.
