Abstract

The self-centering energy dissipative (SCED) brace is an advanced cross-bracing system that has recently been developed in Canada. Its self-centering capability reduces or eliminates residual building deformations after major seismic events and prevents progressive drifting to occur under long duration strong ground motion inducing inelastic cyclic structural response. The system can be utilized in new structures as well as for the seismic retrofit of deficient structures. A description of the bracing system is presented, together with possible applications where SCED braces are used in braced steel frames or in combination with other seismic force resisting systems. Time-history responses of sample structures are presented and discussed. Hysteretic responses from full-scale SCED braced frame tests are presented. An ongoing shake table test program carried out on a 1/3 scaled three-story SCED braced frame is described and preliminary results are presented.
