Title

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

Pages

  1-13

Abstract

 The effectiveness of multiple tuned mass friction dampers (MTMFD) for vibration control of structure over a single tuned mass friction damper (STMFD) is investigated. A five story structure supported with MTMFD is considered and the governing differential equations of motion are derived. The response of the structure under four selected earthquake ground motions is obtained by solving the equations of motion numerically using the state space method. The number of damper in MTMFD is varied and the response of five story structure with STMFD is compared with the response of the same structure with MTMFD. A parametric study is also conducted to investigate the effects of important parameters such as number of dampers in MTMFD, damper FREQUENCY SPACING, MASS RATIO, TUNING RATIO and damper SLIP FORCE. It is found that for a given structural system and level of excitation an optimum value of the parameters (i.e. FREQUENCY SPACING, TUNING RATIO and damper SLIP FORCE) exists at which the peak displacement of structure attains its minimum value. The response time history of the structure with STMFD and MTMFD with respect to their optimum parameters is compared. It is found that the MTMFD is more effective in controlling the response of the structure in comparison with the STMFD having the same mass.
