SEISMIC PERFORMANCE ASSESSMENT OF REINFORCED CONCRETE STRUCTURES: A COMPREHENSIVE REVIEW OF EXPERIMENTAL AND NUMERICAL STUDIES

Abstract

This comprehensive review examines experimental and numerical investigations of seismic performance in reinforced concrete (RC) structures. The study synthesizes findings from advanced testing methodologies, including quasi-static cyclic loading and dynamic time-history analyses, alongside sophisticated finite element modeling techniques. Key performance indicators such as ductility, hysteretic behavior, energy dissipation capacity, and damage progression are evaluated across various structural typologies including columns, frames, beam-column joints, and shear walls. Special attention is devoted to the effects of material degradation, corrosion, and retrofitting strategies on seismic resilience. Probabilistic seismic demand models and fragility analysis frameworks are reviewed to assess vulnerability of RC structures under earthquake loading. The integration of experimental validation with numerical simulation provides critical insights for performance-based seismic design and the development of enhanced safety standards for earthquake-prone regions. Future research priorities include long-term durability assessment, hybrid fiber systems, and computational efficiency improvements for large-scale structural systems.
