摘要

Buckling-restrained braced frames (BRBFs) have been shown to exhibit very favorable energy-dissipating characteristics. Nevertheless, low post-yield stiffness of the braces leave the system vulnerable to unfavorable behavioral characteristics such as large permanent drift. This paper reports the results of a study conducted to investigate the potential benefit of using buckling-restrained braces in a dual system to minimize permanent deformations. Results from nonlinear time-history analyses demonstrate significant improvements in maximum and residual drifts using the dual system.
