摇摆墙体系研究现状与发展

Research situation and development of the rocking wall system

建筑结构功能可恢复已经成为防震减灾的重要研究方向。已有研究表明,摇摆墙可协调框架结构的变形模式,改善结构损伤机制,节约结构造价;同时能够将可恢复功能结构的三种实现途径:摇摆、自复位、可更换,进行统一,吸引了国内外学者的广泛研究。本文首先回顾了摇摆结构的由来,介绍了框架-摇摆墙结构体系的工作机制与破坏模式。对不同材料属性的单肢摇摆墙、双肢摇摆墙,以及连续摇摆墙的现有研究展开了综述。归纳了框架-摇摆墙结构设计方法以及摇摆墙与基础和框架的连接设计,介绍了与摇摆墙功能类似的结构形式。最后总结了摇摆墙结构的优势特点和目前存在的主要问题,并对摇摆墙结构体系的发展趋势进行了展望。

Seismic resilience of structures has become an important research direction of earthquake prevention and disaster reduction.The existing research shows that the rocking wall can coordinate the deformation mode of the frame structure,improve the structural damage mechanism,and save the structural cost;Meanwhile,the rocking wall can unify the three methods for improving structural seismic resilience:rocking,self-centering and replaceable,and has attracted extensive research from domestic and foreign scholars.In this paper,the origin of rocking structure is reviewed,and the working mechanism and failure mode of frame-rocking wall structural systems are introduced.The existing research of rocking wall with different material properties,hybrid rocking wall and continuously rocking wall are reviewed.The design method of the frame-rocking wall is concluded,as well as the connection design between the rocking wall and the foundation and frame.And the structures with similar functions as the rocking wall are presented.Finally,the characteristics and main problems of the rocking wall structure are summarized,and the development trend of the rocking wall structure system is prospected.
