防屈曲支撑的设计标准建议
|
摘要
防屈曲支撑作为一种宏观上不发生屈曲的抗侧力和结构保险丝构件,目前在我国地震区的工程结构中已有一定规模的应用,但总体上说,国内的研究还暂时未能赶上工程应用的步伐,现有设计标准也未尽完善,为这种支撑的抗震安全性埋下隐患。鉴于此,作者在国内外研究成果的基础上并结合相关经验,从防屈曲支撑的选型、构造、设计、加工及检验五大方面,就其中可能被学术界和工程界忽视的关键问题给出相关建议,希望借此抱砖引玉,以进一步完善相关设计标准,并为此类支撑的实际应用提供更可靠的技术保障。
Buckling-Restrained Braces( BRBs),as both lateral-load-resisting and structural fuse members,are now gaining wide acceptance and used in engineering structures in seismic-prone areas of China. However,the researches related to BRBs have always been left behind by engineering applications and the current design standards have yet to be improved,which raises concerns for seismic design of this type of braces. In view of this, several design recommendations for BRBs in terms of type selection,constructional details,design,fabrication,and examination,which may be ignored in academic circles and engineering,are presented in this paper based on previous research findings and design experience. It is hoped that these recommendations will further improve the corresponding design standards and provide more technical support for actual applications of BRBs.
