Abstract
Passive energy dissipation technique is widely adopted in the design practices to improve the seismic performance of structures. Metallic dampers are considered as one of the cost-effective passive devices available till date. This seminar was focused on the recent advances on the various types of metallic dampers and their applications in seismic retrofitting of structures. Specifically, Buckling –restrained braces (BRBs), Shear and flexure yielding devices (SAFYDs), and Steel Plate Shear walls (SPSWs) were discussed in detail. The applications of these device in controlling the seismic collapse of deficient non-ductile RC frames will be presented. The seminar also touched upon the real-time hybrid simulation and testing technique to evaluate the seismic performance of structures. Finally, the scope and funding availability for higher studies at Indian Institute of Technology (IIT) Delhi were presented in the seminar.
