Six novel types of tuned liquid dampers (TLD) is presented, in which sloped bottom tuned liquid damper, tuned magnetic fluid damper (TMFD) and conical tuned liquid damper are mainly designed to optimize the control force for reducing structural vibrations; while the water sloshing damper with embossments (WSDE) and tuned liquid damper with slat screens are mainly designed to increase energy dissipation inside the liquid filled tank; and tuned liquid damper with baffles is designed to broaden the effective frequency spectrum of the tuned damper system. Further, a controllable TMD-TLD hybrid system (CTTHS) is also developed herein. The CTTHS is capable of guaranteeing the reduction effect of a structure in case structural frequency excursion happened in engineering vibration.
