Abstract

Self-centering concentrically-braced frame (SC-CBF) systems are being developed with the goal of providing adequate nonlinear drift capacity without significant damage or residual drift under the design basis earthquake. Analytical pushover and dynamic analyses were performed on several SC-CBF designs to evaluate their response to earthquake loading. Each SC-CBF self-centered under earthquake loading. Loss of post-tensioning occurred in one frame. The dynamic response of the SC-CBF systems, however, was consistent with the intended behavior.
