Reinforced concrete (RC) is a widely used building material known for its strength and durability. By combining the compressive of with tensile properties steel, RC structures can withstand significant loads, making them ideal buildings critical infrastructure. This adaptability has made preferred choice in urban construction, especially developing regions such as Juba South Sudan. However, are particularly vulnerable due to lack formal seismic design standards, inadequate reinforcement details, limited awareness earthquake-resistant practices. Consequently, many regional need be better designed forces, increasing risk failure during earthquakes. study evaluates behavior typical G + 2 frame Juba, initially gravity loads when subjected forces.

Assessing Seismic Vulnerability Methods for RC-Frame Buildings Pre- and Post-Earthquake

Sustainability, Journal Year: 2024, Volume and Issue: 16(23), P. 10392 - 10392

Published: Nov. 27, 2024

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.
