摘要:
Developing effective, reliable, and economical structural vibration control techniques has always been a critical research topic in civil engineering community. Negative stiffness, as the opposite of positive stiffness, can decrease the total stiffness of the entire system and assist structural motion rather than resisting it, thus provides a new perspective on developing more effective structural vibration control techniques. Negative stiffness has attracted considerable research attention since it was first proposed, and various negative stiffness elements (NSEs) and NSE-based structural vibration control devices have been developed and extensively investigated. This paper provides a comprehensive review on NSE-based structural vibration control techniques, which begins with the concept of negative stiffness and physical realizations of NSEs. Following that, different types of NSEbased structural vibration control devices and systems are introduced accompanied by their applications and superiorities over conventional vibration control devices. Some challenging problems and possible research topics worth further exploration are also presented.
