Abstract
ABSTRACTInfill walls, often regarded as non-structural components, significantly influence the seismic behavior of reinforced concrete (RC) framed structures. This study presents a comprehensive review of recent literature focusing on the role of infill walls under lateral seismic loading. Various analytical and numerical modeling techniquessuch as the equivalent diagonal strut method, double-strut models, and advanced finite element approachesare explored to assess their effectiveness in capturing infill behavior. Key parameters affected by infill presence, including base shear capacity, story drift, stiffness, and ductility, are examined across different structural configurations, including soft-story, vertically irregular, and asymmetrical buildings. The review highlights the impact of partial infills, wall openings, and irregular infill distributions on seismic performance. It also discusses the importance of user-defined nonlinear hinge models over default software settings for accurate response prediction. The findings emphasize the need for incorporating infill wall effects into design and code provisions to enhance the safety and resilience of RC buildings in seismically active regions.
