This paper presents the results of experimental research on the shear crack resistance of I-shaped beams with BFRP transverse reinforcement. The tested specimens had equal sizes and different angles of stirrups inclination, web reinforcement ratio, and shear span-to-depth ratio (a/d). The group with a/d = 2.5 and 3.2 also included beams with cold-drawn wire transverse reinforcement. The effect of varied parameters on the load of shear crack formation and the width of the cracks is analyzed. The maximum shear crack width in beams with inclined stirrups was slightly lower than that of beams with vertical stirrups. The corresponding difference in the crack width between twin beams differing only in the angle of stirrups inclination was up to 10% and was more pronounced for beams with a/d = 3.2. In most cases, the shear crack width for beams with BFRP transverse reinforcement does not exceed the permissible values established by the codes of different countries. The exceptions mainly comprised beams with the lowest web reinforcement ratio.
