Seismic Behaviour of RC Frames with Masonry Infills

This lecture covers the seismic behaviour of reinforced concrete frames with unreinforced masonry infills, focusing on the interaction between the two elements. It discusses the out-of-plane failure of masonry infills due to accelerations, the influence of in-plane cracks on the infill's capacity, and the importance of considering masonry infills in the structural response. The instructor emphasizes the risks associated with partially infilled frames and provides recommendations to avoid shear failure, such as separating the infill from the structural elements and stabilizing it to prevent dislodgement during seismic events.
