On the Study of a Shear Building Seismic Response, Controlled Passively and Actively by Tuned Mass Damper(TMD) and Comparison with Uncontrolled Case

The behaviour of structures in recent years indicates that moderate and severe earthquakes result in substantial damages, extensively higher than what is expected. One solution in order to reduce the seismic response especially in relative story displacements is usage of tuned mass dampers (TMD). In this study, the comparisons between uncontrolled and active/passive controlled cases have been evaluated based on MATLAB-based code. Ultimately, results for an 8-story shear building under specified records shows that ATMD has more appropriate efficiency compared to PTMD. In addition, implementing PTMD would lead to more desirable results in comparison with uncontrolled case regarding acceleration and displacement time history responses.
