Many prediction criteria for evaluating the ultimate strength of high strength concrete deep beams are compared in this research. Added to the theoretical values obtained by the equations, a strut and tie model was developed, using the load path obtained by the Finite Element Method. The values found are also compared with test results in three high strength concrete deep beams with web openings. The test specimens consist of simply supported deep beams with openings located next to one of the supports. It is shown that there is great difference in the values encountered by theoretical analysis, and only ACI's prediction gets close to the test results, in spit of not considering the opening.
