Under single loading, the gutters exhibit smaller deformations compared to repeated loading. For example, at a load of F = 10.83 kN, the deformation reaches Δl = 0.59 mm, which is lower than under repeated loading (Δl = 1.29 mm). This difference may be attributed to the fact that single loading does not allow the material to accumulate progressive changes. 4. Conclusions 1. The investigation of the stress-strain state of SFRC gutters demonstrated that they exhibit high stiffness and crack resistance under repeated low-cycle loading. Deformations in the initial loading cycles were minimal and increased significantly only in the later cycles, confirming the high effectiveness of SFRC as a structural material for drainage gutters. 2. A comparison of deformation values obtained under single loading to failure and during repeated loading (11th cycle) shows an increase in deformation by a factor of 2 to 3.7. 3. SFRC gutters demonstrate high resistance to repeated low-cycle loading, which makes steel fiber reinforced concrete a promising material for application in road and hydraulic engineering structures.
