Discrete fibers are often used as reinforcement to increase the tensile and shear strengths of concrete. For many years, the behavior of fiber reinforced composite members has been investigated both experimentally and analytically. The influence of fibers on the behavior of shear critical members is quite significant, therefore, it is inevitable to develop a method, which estimates the shear strength of fiber reinforced composite deep beams realistically. This is why one of the main objectives of this study is to propose a shear strength equation and a method to obtain the flexural strength of deep beams and coupling beams with different types and amounts of fibers and reinforcement detailing under varying loading conditions. The predicted shear strengths and strengths computed from equations recommended by other researchers are then compared with the experimental results that are tabulated in a database constructed for this analytical study. Another main purpose of this study is to recommend a model that can be utilized in the nonlinear analysis of coupling beams. When the analytical results obtained from the proposed method are compared with the experimental results, it is observed that the behavior is predicted with adequate accuracy, even for coupled wall systems.
