NUMERICAL ANALYSIS ON THE DAMPING EFFECT OF STRUCTURE WITH TUNED LIQUID DAMPERS SUBJECTED TO SEISMIC EXCITATIONS

TLD is an efficient passive control device for vibration energy-dissipating,whose rule and analysis design method have received much attention. Actually,the previous researches were mainly relied on?tests and have 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 to conduct the seismic response analysis of fluid-structure interaction in a high-rise frame structure controlled by installing TLD of roof tank. Meanwhile,earlier test rules and simplified methods are also compared and checked in this paper. Besides,the calculation and?modeling of fluidstructure interaction are initially explored and examined,whereby realizing the TLD numerical modeling of fluidstructures interaction as well as summarizing the TLD damping of vibration rule of high-rise frame structure.
