Abstract:

Tuned Mass Damper (TMD) is a passive control device which is simple, inexpensive and a reliable means for suppressing undesirable vibration of structures caused by harmonic or wind excitation. The effect of TMD with optimum parameters (frequency and mass ratios) is studied. In the present paper, a soft storey constructed at the top of a building is treated as a TMD and its usefulness in response reduction is evaluated. Analysis and modeling are done using FE software developed by VSSC, FEASTSMT and the building is subjected to an arbitrary acceleration as base excitation to record the response at top storey. TMDs with mass percentages of 2 and 3 are considered and the results are compared between buildings with and without TMD.
