Title

SEISMIC RESPONSE OF MULTI-STORY STRUCTURE WITH MULTIPLE TUNED MASS FRICTION DAMPERS

Pages

  81-92

Abstract

 The effectiveness of passive multiple-tuned mass friction dampers (P-MTMFDs) over a single passive-tuned mass friction damper (P-TMFD) is investigated. The governing differential equations of motion are solved numerically using state-space method. The response of a five-story structure is investigated for four considered earthquake ground motions. The number of P-TMFD units of P-MTMFDS is varied and the response of five-story structure with single P-TMFD is compared with the response of the same structure with P-MTMFDS. A parametric study is also conducted to investigate the effects of important parameters like number of P-TMFD units in P-MTMFDS, frequency spacing, MASS RATIO, TUNING RATIO and damper slip force. It is found that at a given level of excitation; an optimum value of considered important parameters exists at which the peak displacement of structure attains its minimum value. The response time history of the structure with single P-TMFD and P-MTMFDS, with respect to their optimum parameters is compared. It is found that the P-MTMFDS are more effective in controlling the response of the structure to which it is attached in compare to the single P-TMFD having same mass.
