Confined masonry is one of the popular construction systems, consisting of a masonry panel encased by concrete tie beams and columns. Unlike infilled frames, the masonry panel is built first, and then the concrete of the confining elements is cast against the boundaries of the panels. The combined wall and confining elements jointly resist both the vertical and lateral loads. Limited research has been carried out on such building system using local Egyptian materials and construction techniques. Furthermore, techniques and methods to strengthen existing structures have not been thoroughly investigated. In this respect, A research project has been developed to investigate the behavior and response of confined masonry walls under various design, construction and testing conditions. The aim of this thesis is also to study the lateral load behavior of strengthened confined masonry walls using fiber reinforced polymers (FRP).
