减隔震技术在航站楼大跨结构中的应用
|
摘要
建筑结构减隔震技术在国内外得到了极大的发展和应用,已经比较成熟,为工程防震减灾领域带来了新的思路和方法.目前采用隔震技术的结构大多为较规则的混凝土框架、框剪、剪力墙结构,而且单体规模较小.对于单体超大、体型复杂的大跨度空间结构采用隔震技术的工程较少,相应的研究也不多.本文结合昆明新机场航站楼和深圳机场T3航站楼工程减隔震结构设计的具体情况,介绍减隔震设计在航站楼大跨结构中的应用,得到了一些有意义的结论,可为同类结构的设计研究提供借鉴.
Seismic base isolation design for building structures has a fast development and wide application in China and abroad.Such technology has already become mature,rendering new ideas and solutions to the earthquake prevention and disaster reduction in structural engineering.At present structures that employ base isolation technique mainly include RC frames,frame-shear wall and shear wall structures with regular configurations,which are usually of small scale for a single building.In comparison,there are fewer researches and applications of the seismic isolation technology in large span structures with giant and complex configuration.This paper introduces the seismic isolation design on the terminal building of Kunming new airport and the Terminal T3 of Shenzhen Baoan Airport,and thereby reviews the present applications of the seismic isolation and mitigation technologies in large span structures of airport terminal buildings.Some practical conclusions have been reached,providing reference to the design and research of other structures of the same kind.
