Application of Tuned Mass Damper for Vibration Control of Multistoried Building under Seismic Excitation
Journal Title: GRD Journal for Engineering - Year 2017, Vol 2, Issue 6
Abstract
Current trends in construction industry demands taller and lighter structures, which are also more flexible and having quite low damping value. Now-a-days several techniques are available to minimize the vibration of the structure, out of the several techniques available for vibration control; concept of using TMD is a newer one. This study was made to study the effectiveness of using TMD for controlling vibration of structure. The numerical stimulations are performed to study the structure with and without TMD. A twelve storied building with rectangular shape is considered for analysis. Analysis is done by FE software SAP2000 by using direct integration approach. TMDs with percentage masses 2%, 3%, 4%, 5% are considered. Three different recorded time histories of past EQ are used for the analysis. Namely 1940 EL-Centro EQ, Northridge EQ, and Taft EQ. comparison is done between the buildings with TMD and without TMD. From the study it was found that, TMD can be effectively used for vibration control of structure. TMD was more effective when damping ratio is less. Gradually increase in the mass ratio of the TMD result in gradually decrement in the displacement response of the structure.
