When a tall building is subjected to earthquake under the action of lateral loads, providing a suitable lateral force resisting system has a significant effect on the performance of the RC frame structure. The present study focuses on the study of system based strengthening systems for RC frame structure. The effectiveness of different locations of shear wall and X bracing on the RC frame structure has been carried out. For this study, a G+9 storied RC frame structure has been considered and structural behavior has been studied for time history at Pin Code: 370020 (Bhuj, Gujarat, India) taken of 2001-01-26 at 03:16:40 UTC of magnitude (M7). The RC frame structure models are analyzing by nonlinear dynamic time history as per IS 1893:2016(part1) using SAP2000 software. A comparative study has been performed on parameters namely, joint displacement, base shear, maximum bending moment, shear force and time period on the considered RC bare Frame and system based strengthening systems, thus, six number of models have analyzed and compared. From the study, it has been observed that the joint displacement of the bare frame with shear wall on corner edge decrease in the structure as compared to the bare frame in seismic zone V. Base shear value increases in the strengthened RC frame in comparison with bare frame. Maximum bending moment, maximum shear force value and time period values in frame model with shear wall and X bracing get reduced as compared to frame model without them. In the present study, analysis of G+9 story RC frame with and without system-based strengthening has been performed by nonlinear time history analysis using SAP2000, conclusions inferred is that the shear walls configured with the shear wall on corner edge with bare frame have been found beneficial as compared with other models.
