In this chapter, the different modeling strategies for simulating the behavior of masonry infilled frames are investigated. Particular emphasis is given on the suitability of the discrete element method (DEM) to accurately represent the mechanical behavior, strength and ductility of concrete and brickwork masonry infilled frames. Within DEM, masonry infill panels are represented by individual bricks and blocks separated by zero thickness interfaces representing mortar joints. The assumptions adopted, the numerical implementation and the advantages and disadvantages of modeling masonry infilled frames using the discrete element method are discussed. This ‘discontinuum’ approach, an alternative to modeling masonry as a homogenized continuum, is particularly suited for studying the mechanical behavior and interaction between the individual masonry brick/blocks and their interaction with the framed structure
