Abstract: This study evaluates the cost-benefit ratios of carbon wrapping and concrete jacketing as seismic retrofitting techniques for reinforced concrete (RCC) hospital buildings. By reviewing existing literature and case study data, it underscores the efficacy and economic viability of these approaches. Experimental and numerical studies on two RCC hospital structures demonstrate significant improvements in stiffness, strength, and ductility with both techniques. Carbon wrapping is shown to effectively reinforce structures, addressing vulnerabilities and enhancing seismic resilience, while concrete jacketing offers greater economic feasibility in normal and moderately stressed conditions, performing comparably or slightly better in critical limit states. The analysis provides crucial insights for stakeholders, supporting informed decisions that balance structural integrity and cost-effectiveness. This research aims to guide retrofitting efforts by presenting a comprehensive evaluation of the economic and structural benefits of these two techniques, helping decision makers optimise solutions that prioritise both financial and structural outcomes.
