The objective of this course is to assist professional engineers in understanding how to perform structural assessment and nonlinear analysis of existing concrete buildings with masonry infill walls.Reinforced concrete (RC) frames with unreinforced masonry (URM) infill walls are commonly used as the structural system for buildings in many seismically active regions around the world.
Structural engineers recognize that many buildings of this type have performed poorly during earthquakes. During earthquakes, infill walls affect the response of the structure, and may have either beneficial or detrimental effects. Infill walls contribute to the lateral force resisting capacity and damping of the structure up to a certain level of ground motion. Infill walls increase the initial stiffness and decrease the fundamental period of the structure, which might be beneficial or detrimental, depending on the frequency content of the ground motion.
URM infill walls are prone to early brittle failure, and infill wall failures may lead to the formation of a weak story, which can cause the building to collapse. Infill walls interact with the surrounding frame in such a way that column shear failure is made more likely.In addition, an unequal spatial distribution of infill walls for functional reasons – for example, windows and open commercial spaces on the street frontage and full walls adjacent to neighboring buildings – can create torsion that places additional demands on columns and may cause them to fail.Because of the potentially dire consequences of ignoring the structural role of URM infill walls, proper consideration of infill walls is essential in any structural analysis of RC frame buildings with infill walls. This course provides engineers with guidance on how to model infill walls and include them in structural analyses.
