The present project involves the seismic evaluation and retrofitting of a four-story reinforced concrete building. A 3D model of the building was developed and evaluated using ETABS. The building foundation was examined using SAFE. Based on the evaluation results, the structure was found to be inadequate against seismic loads. To improve the seismic performance of the building, Buckling Restrained Braces (BRBs) were introduced as a supplementary lateral load-resisting system. Due to the implementation of the new structural system, piles were used to strengthen the foundation. The construction drawings were prepared using AutoCAD.
