摘要

The numerical modeling and seismic performance of reinforced concrete structures with unreinforced masonry walls are reviewed in this work. It explores the behavior of infill walls under in-plane and out-of-plane loads, highlighting their contribution to increased stiffness and energy dissipation, as well as their potential to cause brittle failure or soft-story mechanisms. The paper emphasizes the need for careful consideration of these factors in seismic design, particularly in earthquake-prone regions such as Algeria, where past seismic events have exposed vulnerabilities in buildings with inadequately modeled infill walls. The review also examines various numerical modeling approaches, including micro-modeling and macro-modeling, which offer valuable insights into the complex behaviors of these structural systems. The findings suggest that optimizing the distribution of infill walls and exploring new materials and retrofitting techniques are essential for enhancing the seismic resilience of buildings.
