Unreinforced masonry systems consist of a composite of bricks, often made from clay or concrete blocks, and mortar joints. Across the past centuries, masonry has been described as one of the most reliable and durable building systems that humans have built in many historic civilizations throughout the world, although they lack sufficient strength to resist strong ground motions. Nevertheless, the wide demand for such building systems also comes from their ease of construction and formation. Obviously, masonry systems are designed to carry out and resist vertical and the horizontal loads. However, during past and the recent earthquakes, the vulnerability of traditional masonry systems has been addressed. It has been noticed that the resistance of masonry buildings to tension or lateral
dynamic loads, as well as vertical or compressive loads, is significantly different than inthe case of isotropic or homogeneous materials. Despite the wide use of some modern building materials such as steel and reinforced concrete, masonry building systems are still used. However, the development of a modern masonry construction system using fully reinforced or partially grouted masonry has improved the performance of masonry systems in terms of resisting the
tension and the shear forces generated in high seismic activity regions.
