13th World Conference on Earthquake Engineering Vancouver, , Canada August 1-6, 2004 Paper No. 3351 Bracing Systems FOR Seismic Retrofitting OF Steel FRAMES Luigi DI SARNO1 and Amr S. ELNASHAI2 SUMMARY The present study assesses the Seismic performance of Steel moment resisting frames (MRFs) retrofitted with different Bracing Systems . Three brace configurations were utilized: special concentrically braces (SCBFs), buckling-restrained braces (BRBFs) and mega-braces (MBFs). A 9-storey Steel perimeter MRF was designed with lateral stiffness insufficient to satisfy code drift limitations in zones with high Seismic hazards.
