Experimental study of the restoring force mechanism in the self-centering beam (SCB)

Abhilasha MAURYA,Matthew R. EATHERTON

Frontiers of Structural and Civil Engineering 2016, Volume 10, Issue 3,   Pages 272-282 doi: 10.1007/s11709-016-0346-x

Abstract: In the past, several self-centering (SC) seismic systems have been developed.However, examples of self-centering systems used in practice are limited due to unusual field constructionA self centering beam moment frame (SCB-MF) has been developed that mitigates several of these issuesThe self-centering beam (SCB) is a shop-fabricated, self-contained structural component that when implementedThe limit states that cause a loss in system's restoring force which lead to a decrease in the self-centering
