Abstract:
Presented a pool-type tuned mass damper(TMD), in which the synthetical effects of both tuned liquid damper(TLD)and TMD were considered simultaneously. The equations of motion of the structure with a pool-type TMD, TMD or TLD were formulated. An indoor swimming pool was taken as an example to investigate the control performance of this new pool-type TMD. The control effectivenesses of the pool-type TMD system with various pool-lengths along vibration direction were also computed and compared with that of the corresponding TMD, TLD system under wind or earthquake excitations respectively. The suggestions for designing a pool-type TMD were provided through phase difference analyses. The results show that the optimally designed pool-type TMD can achieve a performance level which is close to that of an ordinary TMD, while both TMDs far outperform TLD. Compared with ordinary TMD, the pool-type TMD has more economical and practical values.
