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.

Development and analysis of passive energy dissipation system for steel moment resisting frame

The seismic vulnerability of steel moment resisting frame with passive dampers is assessed with 13 different seismic resisting systems. The structural frames are analysed and designed for the loading conditions in Pune. The stiffness effect on the stories is demonstrated through the lateral displacement profile of the building. Hybrid passive dampers with buckling restrained brace of mild steel and aluminium are used to improve lateral stiffness of the structure. Mild steel braces have increased lateral strength and proved to be good energy dissipating devices. The aluminium sections are chosen as energy dissipating device due to its low yield strength. Aluminium buckling restrained braces has improved performance of the structure in the form of reduced storey drift and displacement as compared to basic steel moment resisting frame. By the use of these devices either alone or in combination with BRB, the performance of SMRF has been improved significantly. Copyright © 2015 Inderscience Enterprises Ltd.

Effect of energy dissipating devices on storey drift and displacement by nonlinear time history analysis

The seismic performance assessment of modified steel moment-resisting frame (SMRF) was carried out by nonlinear time-history analysis. The basic bare SMRF was reduced in strength first and then enhanced by installing passive energy dissipating devices (EDDs) to develop modified frame. Passive EDDs comprise both rate-dependent and rate-independent devices. Viscous fluid damper (VFD) is a rate-dependent device whereas buckling-restrained brace is a rate-independent device. The lateral strength of structure was improved by using these devices either alone or in combination. Seven-scaled time-history records were used for incremental dynamic analysis. The stiffness effect on the stories is demonstrated through the lateral displacement profile of the building. The VFD is found to be a good EDD as it significantly improved the performance of the frame at all levels of seismic analysis.
