The article presents the test results of concrete beams reinforced with basalt fiber polymer and carbon fiber plastic brought to the ultimate state in previous researches. The nature of their deformation, crack development and fracture was established, that in the beams with large (a/d = 3) and central (a/d = 2) shear spans corresponded to the stress-strain state of almost balanced normal cross section. The destruction of the beams with small (a/d = 1) shear spans was accompanied by further opening of previously formed inclined cracks and rupturing of closed carbon fibers on the sides. The bearing capacity of the ultimate limi state support sections of beam constructions with fiber reinforced polymers materials should be determined, first of all, by the action of bending moment on the critical inclined crack. The proposed calculation method provides for the adequate determination of bearing capacity of girder concrete constructions with non-metallic composite reinforcement both without reinforcement and damage, and reinforced by carbon fiber polymers elements that have reached the limit state (ULS).
