结构抗震设计的新概念——可恢复功能结构

New Concept of Structural Seismic Design:Earthquake Resilient Structures

摘要:

可恢复功能结构是一种新型的减震控制结构,它不仅能在地震时保护人们的生命财产安全,也能帮助人们在大地震之后,尽快恢复正常生活,是结构抗震设计的一个理想的新方向.可恢复结构体系主要包括可更换结构构件,摇摆结构,以及自复位结构等.针对21世纪以来国内外可恢复结构体系的研究现状进行了综述分析,详细介绍了正在研究的两种双肢剪力墙可更换构件即可更换连梁与可更换剪力墙脚部构件的设计概念.

Abstract:

Earthquake resilient structure is a new branch of the seismic structural design.The new structural system is not only capable of preventing from the structure failure so as to protect people’s life safety during an earthquake,but also restoring immediately the structural function after an earthquake.A research was made of several kinds of resilient structures such as replaceable structure,rocking wall,rocking frame and selfcentering structure.The paper presents a summary of the recent research on different kinds of resilient structures,and also a new replaceable technology for coupled shear wall,replaceable coupling beam and replaceable shear wall toe.
