Due to the absence of study deals with the effect of SIFCON on deep beams, this study was conducted. The mechanical properties; compressive, tensile, flexural and shear strength were tested. The second aspect was the study of behavior of SIFCON deep beams with and without openings. The study was divided into two groups. The first group was prepared to cover the following cases: variation in SIFCON ratio, the effect of shear span to depth ratio, removing of vertical steel and removing of mesh reinforcement. While, the second group was prepared to study the following cases: variation in SIFCON ratio, openings reinforcement effect and effect of opening shape. The increase of SIFCON ratio by (6% to 9%) gave increasing in the cracking and ultimate load compared with a deep beam of conventional concrete. In addition, it was removed either vertical reinforcement or all reinforcement, it showed an increase in ultimate load for solid deep beams with SIFCON of (9%) increased than the conventional concrete. The results showed that the ultimate load was increased with decreasing the effective shear span to depth ratio. The SIFCON deep beam with inclined reinforcement around the openings gave increasing in the ultimate load than the conventional concrete deep beam with inclined reinforcement. Also, the SIFCON deep beam with circular opening gave high cracking and ultimate loads than square and triangular openings. The toughness and ductility were increased for all SIFCON deep beams.
