Hysteretic Performance Analysis of Self-Centering Buckling Restrained Braces Using a Rheological Model

AbstractIn this paper, a cyclic elastoplastic model applicable for studying the hysteretic performance of self-centering buckling restrained braces (SC-BRBs) is established based on the rheological analysis method. The linear-elastic pretensioned rods and superelastic shape memory alloy (SMA) pretensioned rods can be taken into account, and the tube stiffness modification coefficient in consideration of fabrication tolerances is introduced in this model. In the proposed rheological model simulating the SC-BRB specimens, the prediction of the hysteretic performance accurately matched the experiments. The proposed rheological model was applied to study the influence of the key structural parameters on the SC-BRB hysteretic performance: the energy dissipation of SC-BRBs with SMA pretensioned rods is superior to that of linear-elastic pretensioned rods; an increase of pretension and the area of the pretensioned rods will have different impacts on the hysteretic performance of SC-BRBs with linear-elastic prete...
