NUMERICAL MODELING ON THE DAMPING CONTROL OF TLD STRUCTURE

TLD is an efficient control mode of passive dissipative damping of vibration, of which the rule and analysis design method have received much attention. Actually, most previous research was relied on tests and has got fruitful achievements in the damping of vibration rule. Though the simplified analysis method of damping of vibration effect has also been developed based on those tests, its application has been greatly limited due to the rough models. Recently, with the development of computer technology, it is likely to do research into TLD numerical modeling analysis of fluid-structure interaction, which would become a valuable supplement. The fluid- structure interaction of general structural analysis software ADINA is applied in this article to conducting the seismic response analysis of fluid- structure interaction in the high-rise frame structure controlled by TLD of roof tank installation. Meanwhile, earlier test rules and simplified methods are also compared and checked in this paper. Besides, the calculation and model building of fluid- structure interaction are initially explored and examined whereby realizing the TLD numerical modeling of fluid- structure interaction as well as summarizing the TLD damping of vibration rule of high-rise frame structure
