The seismic vulnerability of reinforced concrete (RC) buildings has been an important issue, especially in earthquake-prone regions with limited design codes such as South Sudan. Improving the performance is critical for maintaining structural functionality under normal service loads and rapid recovery after natural disasters earthquakes. This research aims to thoroughly assess methods used evaluate RC frame structures pre- post-earthquake scenarios. primary objective provide a comprehensive framework that integrates empirical, analytical, experimental methods, categorizing existing assessment proposing improvements resource-constrained environments. However, empirical have always historical earthquake data estimate potential damage. In contrast, analytical computational tools fragility curves probability damage at different intensities. Additionally, shaking table tests pseudo-dynamic analyses, validated theoretical predictions provided insights into behavior simulated conditions. Furthermore, key findings highlight vulnerabilities buildings, quantify probabilities, compare strengths limitations methods. challenges availability, limitations, difficulties replicating actual conditions test setups areas improvement. By addressing these challenges, review provides recommendations future studies, including integrating advanced regional hazard characterization improving enhance accuracy assessments, ultimately supporting more resilient increasing disaster preparedness.
