Seismic Behaviour of Unreinforced Masonry Buildings

This lecture covers the seismic behavior of unreinforced masonry buildings, focusing on their vulnerability under earthquake loading, failure modes, structural features, and in-plane behavior. It discusses the classification of masonry, failure mechanisms of URM structures, and failure mechanisms of RC frames with URM infills. The lecture also delves into the importance of structural features like regularity, redundancy, and box behavior in URM buildings. Additionally, it explores the in-plane behavior of URM walls, including their strength capacity and drift limits. Various literature references are provided to support the content discussed.
