摘要

The seismic response of Buckling restrained braced frames (BRBF) and self-centering braced frame (SCBF) is compared when used in building structures of 3 to 6 stories in height. Ten earthquake ground motion records with 10% probability of exceedance in 50 years (DBE level) and 2 % probability of exceedance in 50 years (MCE level) are used in this study. The SCBF system performs better than BRBF system in terms of mean interstory drift, and the SCBF system has significant smaller residual drifts than the BRBF.
