摘要
本文介绍了可更换连梁的概念与原理,总结了国内外金属耗能型、摩擦耗能型、黏弹性耗能型等不同类型可更换连梁的研究与应用进展,突破以可更换为代价实现结构功能可恢复的思路,提出"功能自恢复结构"(Self-Resilient Structure)概念,达到震后无需更换而功能即可自行恢复的目标。设计了一种功能自恢复连梁(Self-Resilient Coupling Beam),解决了剪力墙结构体系存在的根本性抗震问题,介绍了功能自恢复连梁的构造、原理及特点。
In this paper, the concept and principle of ＂replaceable coupling beam＂（R-CB） are introduced, and the progress of research and application of various R-CBs including different energy-dissipated ways by metallic yielding, friction, viscoelastic behavior, etc is summarized. The concept of ＂self-resilient structure＂ is proposed to break through the traditional thought of restoring structural function by replacing structural components, and to acquire self-resilient function without replacement after the earthquake. In the end, a self-resilient coupling beam （SR-CB） is designed to solve essential seismic problems existed in shear wall structures, while the basic construction, principles, characteristics of SR-CB are also elaborated.
