Abstract:

A tuned hybrid-tanks/mass damper (THMD) system is presented in this paper,and the equation of motion of structure-THMD system is formulated. A phasic difference analysis method is also presented to analyze the dynamic effect of water in hybrid-tanks composed of TLCD and TLD on the control performance of THMD system. Numerical simulation is conducted and performances of an ordinary TMD,TLD,TLCD and THMD are compared under wind and earthquake excitation,respectively. Results show that the designed THMD can achieve a performance level close to that of the ordinary TMD,and outperforms TLD and TLCD. As compared with the ordinary TMD,THMD is more economical and practical.

Key words:  THMD system  phasic difference  control performance
