摘要
目前,阻尼器在工程结构减隔震控制领域的应用已极为广泛,但存在中小地震作用下阻尼器的位移和速度等较小时,阻尼器难以充分发挥耗能能力的问题。因此近年来阻尼器响应放大技术得到了国内外学者的广泛重视,并利用连杆机构、齿轮机构、杠杆机构、跨层支撑等提出了多种阻尼器响应放大装置。全面综述国内外阻尼器响应放大技术的研究和应用进展,包括装置构造和作用机理等。同时,分析现有阻尼器响应放大技术在遭遇极罕遇地震作用时阻尼器更容易失效等方面的不足,指出响应放大技术的研究和发展方向,以期为阻尼器响应放大技术的发展和极罕遇地震作用下确保工程结构的安全提供有效思路。
At present,the damper has been widely used in the field of vibration reduction and isolation control of engineering structures.A problem is,however,that the damper cannot fully exert its energy dissipation capacity,because the displacement and the speed of the damper are small under the actions of small and medium earthquakes.Hence,in recent years,the damper response amplification technology has received extensive attention from scholars at home and abroad,and various damper response amplification devices have been developed by making use of link mechanisms,gear mechanisms,lever mechanisms,cross-layer supports,etc.The research and application progress of damper response amplification technology at home and abroad,including its device construction and action mechanism,etc.,are comprehensively summarized.In the meanwhile,the shortcomings of the existing damper response amplification technology that they are more likely to fail under extremely rare earthquake are analyzed.Furthermore,the research and development direction of the response amplification technology are suggested,providing a reference for the further research of the response amplification technology.The research results provide ideas for the development of damper response amplification technology and ensuring the safety of engineering structures under extremely rare earthquake.
