Abstract
Even though engineers can not design a building which is damage proof during earthquakes and strong winds, the structural control is promising in reducing the vibration of structures. Different from the traditional anti-seismic method, the structural control technique suppresses the structural vibration by installing some devices, mechanisms, sub-structures in the structure to change or adjust the dynamic performance. The structural control system is commonly classified by its device type resulting in four general control types: passive, active, hybrid and semi-active control. In recent years, much attention has been paid to the research and development of structural control techniques with particular emphasis on alleviation of wind and seismic response of buildings and bridges in China. Structural control in civil engineering has been developed from the concept into a workable technology and applied into practical engineering structures. The aim of this lecture is to review a state of the art of researches and applications of structural control in civil engineering in our research group. It includes the passive control, active control, hybrid control and semi-active control. Especially, it focuses on implementations of energy-absorbed devices we developed in real projects. Finally, the possible future directions of structural control in civil engineering are presented.
