APPLICATION OF MAGNETO-RHEOLOGICAL DAMPERS FOR MULTI-LEVEL SEISMIC HAZARD MITIGATION OF HYSTERETIC STRUCTURES

Abstract eng:
A main goal of supplemental control devices is to manage the energy dissipation in the system. Magneto-rheological (MR) dampers have emerged as a promising control device for application to civil structures as they are effective energy dissipators. This paper presents a bang-bang-like control and investigates its ability to mitigate structural response in the presence of hysteretic, geometric and yielding non-linearities under various intensity level seismic hazard suites so as to examine control efficacy and seismic hazard statistics. Results show that MR Dampers limited to realistic peak force/dissipation levels of
