Seismic design of structures generally adopts active or passive control. Active control systems are complex and expensive, while, commonly used passive control systems are difficult to repair after severe seismic actions. This paper presents a new-type beam-column joint dissipating seismic energy via the friction between its different components with relative rotation, then the new beam-column joint is integrated into a high-rise steel structural model with X-shape bracing systems, and this model is analyzed by u-sing the engineering software SAP2000. Comparison between the displacement time-history curves of X-shape braced steel frames with/without new beam-column joints demonstrates that the X-shape braced frame with new beam-column joints has much better performance in resisting severe seismic actions.%结构的抗震设计一般有两类途径:主动控制和被动控制.主动控制系统复杂且成本偏高,普通的被动控制抗震结构强震后修复困难.针对上述问题,本文提出了一种新型转动摩擦耗能梁-柱节点,并基于SAP2000对采用新型梁柱耗能节点的X形支撑钢框架体系和普通X形支撑钢框架体系进行了罕遇地震作用下的时程分析,结果表明采用了该新型梁-柱耗能节点的X形支撑钢框架体系具有更好的抗震性能.
