This study had the purpose of experimentally investigating the influence of cutting off reinforcing steel bars in tension zones on the failure modes and shear strengths of reinforced concrete beams. The main variables were tensile reinforcement ratio, shear-span ratio, stirrup ratio, and cutoff location, and loading was static one-way monotonic loading. As a result, it was learned that the failure modes of such beams can be divided into four classes mainly according to cutoff location and
