Analysis Of Retrofitting Methods For Enhancing Structural Resilience Of RC Moment-Resisting Frame Buildings

Abstract

In earthquake-prone regions, ensuring the operational continuity of critical infrastructure like hospitals is paramount to saving lives. Retrofitting existing structures stands as a proactive strategy to bolster resilience against seismic events. This study compares multiple retrofitting techniques for reinforcing a G+10 RC moment-resisting frame building. We evaluate various jacketing methods such as CFRP, steel, GFRP, and RC through structural analysis using ETABS software and subsequent simulations in ANSYS. The research aims to determine the most effective retrofitting approach, considering factors like structural performance, feasibility, environmental impact, maintenance, and cost-effectiveness. Results indicate that each jacketing material offers unique advantages in mitigating column deformation, providing valuable insights for engineers to enhance structural integrity and community resilience.
