A passive hybrid energy dissipation system (PHEDS) consists of rate dependent devices inseries with rate independent devices, is installed in Steel moment resisting frame (SMRF) toimprove energy dissipation capacity while any seismic event. Analytical development ofmodel in SAP 2000 and performance based design of energy dissipating devices (EDD), werethe basic objectives of the study. High damping rubber damper (HDRD) is a rate dependentdevice whereas elastic springs and buckling restrained braces (BRB) are rate independentdevices. The analytical models confirmed the expected phased behavior and energydissipation capabilities. An incremental dynamic analysis (IDA) was carried out to comparethe effect of energy dissipating devices on overall seismic response of SMRF, a dual BRBSMRFsystem, and a dual PHEDS-SMRF system. The results demonstrate that the PHEDShas potential as an energy dissipation system and improve the performance of the structureduring a seismic event.
