This paper proposes a new seismic retrofit methodology combined with glass fiber sheet (GFS) and non-compression X-brace system using carbon fiber (CFXB) for reinforced concrete buildings damaged in earthquakes. The result reveals that the retrofitting methodology(CR-1, CR-2) proposed in this study is more strengthen than non-retrofit methodology(CS-0) about maximum resisting force and maximum displacement.
