框架-摇摆墙结构设计方法与研究现状分析

State-of-the-art and design methods on frame-rocking wall structures

摇摆墙释放了墙底与基础之间的约束以实现竖向摇摆。已有研究表明:将摇摆墙与RC框架结构结合形成框架-摇摆墙结构体系能有效提高结构的整体承载力及延性,使结构的破坏发生在预期的位置,减少结构地震响应的不确定性。本文首先回顾了摇摆墙的发展历史,简要介绍了框架-摇摆墙结构的基本原理,综述了框架-摇摆墙结构的研究现状,总结了其墙体及连接节点的设计要点并对其未来的发展方向进行展望,指出框架-摇摆墙结构体系后续的研究重点可以包括:墙体与RC框架结构水平连接节点的设计、摇摆墙与基础实现理想铰接的设计、摇摆墙与预制装配式技术结合的设计及摇摆墙墙体在框架结构中布局方式的设计。

Rocking wall releases the constraint between bottom of the wall and foundation to achieve vertical rocking. Previous research has shown that the frame-rocking wall structures system formed by combining rocking wall and RC frame structure can effectively improve the overall bearing capacity and ductility of structure. It also can enable structure damage to occur at expected location and reduce the uncertainty of structural seismic response. This paper briefly reviews development of rocking wall and introduces basic mechanism of frame-rocking wall structures;introduces the research status of frame-rocking wall structures;summarizes design key points of the wall and wall joints of frame-rocking wall structure and points out the future development directions of rocking wall. It is proposed that the future research emphasis in this field can include the design of horizontal connection joints, ideal pin connection between the wall and foundation, combination of prefabricated structures technology and rocking wall and the wall’s arrangement in frame structure.
