新型框架-阻尼框筒结构体系在地铁上盖开发中的应用研究
Study on Application of Frame-Damping-Framed-Tube Structure in Upper Cover of Urban Rail Transit
框架-阻尼框筒结构是一种以“框架-钢板阻尼墙”来近似代替核心筒、框架承担全部竖向荷载的新型结构体系。本文针对框架-阻尼框筒结构在地铁上盖开发中应用的可行性进行研究。多遇地震分析和罕遇地震弹塑性时程分析结果表明,经过良好设计的地铁上盖框架-阻尼框筒结构体系弹性层间位移角和弹塑性层间位移角均能满足地铁上盖结构和框架-剪力墙结构限值要求;罕遇地震作用下阻尼墙充分屈服耗能,地铁上盖整体结构的附加阻尼比可达1.82%,盖上结构的附加阻尼比可达3.45%,具有良好的消能减震效果;与常规框架-核心筒结构相比,框架-阻尼框筒结构取消了核心筒,减少了盖上结构恒载,改善了转换层和盖下结构受力,有利于盖下结构及转换层设计,是一种适用于地铁上盖开发的性能优良的新型结构体系。本文还讨论了盖下结构对框架-阻尼框筒结构性能的影响。相比于嵌固地面时,地铁上盖框架-阻尼框筒受鞭梢效应的影响,高楼层地震响应被放大,在结构设计时应适当提升高楼层的阻尼墙刚度及承载力,以充分发挥阻尼墙的耗能能力。
The frame-damping-framed-tube structure is a new structural system in which the “damping-framed-tube” is used to approximate the core tube, with the frame bearing all vertical loads. This paper investigates the feasibility of applying this new structural system in the development of upper cover of urban rail transit. Elastic analysis under frequently occurred earthquake and elastoplastic time history analysis under rarely occurred earthquake were carried out. Analysis results show that the elastic and elastoplastic inter-story drift of the well-designed upper cover frame-damping-framed-tube structure of urban rail transit can meet the requirements of design standards. Under rarely occurred earthquake, the damping walls yield adequately and dissipate energy, with an additional damping ratio of whole structure up to 1.82% and that of upper cover structure up to 3.45%, showing excellent energy dissipation and seismic mitigation effects. Compared with conventional frame-core tube structures, the elimination of the core tube reduces the dead load of the upper cover structure, improves the load distribution in the transfer level, and benefits the design of the structure below the platform. It indicated that the new structure is suitable for the development of upper cover of urban rail transit. This paper also discusses the influence of the structure below the platform on the performance of frame-damping-framed-tube structure. Compared to being embedded on the ground, the seismic response of high floors of the upper cover frame-damping-framed-tube structure is amplified due to the whipping effect. Therefore, it is necessary to appropriately increase the stiffness and bearing capacity of the damping walls on the high floors to fully utilize their energy dissipation capacity.
