Seismic Engineering: Masonry Structures

This lecture covers the seismic vulnerability of unreinforced masonry buildings, focusing on historical construction techniques, failure modes, and retrofit methods. It discusses the classification of masonry, including stone and brick masonry, and the importance of structural features like regularity, redundancy, and box behavior. The instructor emphasizes the significance of wall-slab and wall-wall connections, diaphragm stiffness, and the interlocking of masonry leaves. Case studies and failure mechanisms of URM structures and RC frames with masonry infills are analyzed, highlighting the impact of roof structures and adjacent buildings on seismic response.
