    Comparative Analysis of Seismic Retrofit Techniques in buildings

    EN This dissertation evaluates the effectiveness of various structural strengthening techniques—shear walls, jacketing, and Fiber Reinforced Polymer (FRP) wrapping—in enhancing the seismic performance of buildings. Through detailed analyses, including pushover analysis, target displacements, chord rotations, and shear force checks, the study assesses each method's impact on structural response under seismic loads. The results show that shear walls provide moderate improvements in stiffness and shear resistance but do not uniformly enhance overall performance. FRP wrapping increases displacement capacity and offers moderate shear resistance, making it a flexible yet less stiff solution. Conversely, jacketing significantly reduces chord rotations and shear forces, providing the best overall improvement in seismic resilience. The findings suggest that jacketing is the most effective method for comprehensive seismic strengthening, offering valuable insights for improving building safety and durability in earthquake-prone areas.
