RECENT ADVANCES IN STRUCTURAL VIBRATION AND FAILURE MODE CONTROL AT HIT: THEORY, EXPERIMENT AND APPLICATION
Structural vibration control can be categorized into passive energy dissipation techniques,semi-active control/smart damping control and active control. Structural vibration control has been developed for four-decades. Recent years, several novel passive control devices have been proposed by the research group at HIT (Harbin Institute of Technology), which are suitable for practical implementations in existing and new buildings. For smart control, first, magnetostrictive composites and their damping properties have been studied. Magnetostrictive composites-based smart dampers and semi-active control of a cable by imcorporating this damper into the stay cable are studied. Then,semi-active control of pounding and unseating effects of highway bridges incorporated with MR dampers is experimentally investigated. Nonlinear structural control algorithms have been theoretically and experimentally studied. The failure mode control for a bridge using various passive dampers and smart damping devices is analyzed and compared with each other. For active control, a hybrid mass damper has been designed and will be implemented into the New Guangzhou TV tower.
