Abstract:

Conventional structure designed in a way that energy dissipation in structure happens through inelastic deformation of structural members. The drawback of this kind of design is permanent deformation in structure which leads in structural permanent deformation. Permanent structural deformation will cause expensive repair process if possible or may lead to collapse of the system under seismic force. Self-centering connection is a new seismicresistance system which has been studied experimentally and numerically during past recent years. Self-centering connections take advantage of gap opening strategy between structural member accompanied by a kind of energy dissipation device to provide energy dissipation property without inelastic deformation in main structural members. Self-centering connection contains post tensioning elements at the connection to take the structure back to its plumb condition. This paper provides a review on the research papers discussing different types of self-centering seismicresistance system. Self-centering connections categorized in self-centering connection with posttensioned elements and self-centering connections with energy dissipation devices and post-tensioned elements.
