Abstract
A self-centering steel moment resisting frame (SC-MRF) for earthquake resistant structures has the attributes of ductility, requires no field welding, and returns the structure to its pre-earthquake position. Post-tensioned high strength strands run parallel to the beam and compress the beam flanges against the column flange to develop the resisting moment to service loading. The behavior of a SC-MRF is characterized by a gap opening and closing at the beam-column interface under earthquake loading. Energy dissipation is provided by supplemental elements that deform under the gap opening behavior. This paper provides a literature review of steel self-centering systems. Then the steel SC-MRF behavior and existing design procedure is described.
