Yasiuk I. Work and bearing capacity of steel fiber reinforced concrete gutters

The dissertation is devoted to the analysis of work and bearing capacity of steel fiber reinforced concrete gutters. As a result of the experimental studies, it was confirmed that the drainage gutters made out of steel fiber reinforced concrete under both one-time and repeated loads have increased bearing capacity, rigidity and crack resistance compared to concrete and reinforced concrete gutters. Conducted the simulation of the work of the steel fiber reinforced concrete gutter by the finite element method (FEM), the influence of the percentage of reinforcement on the stiffness of elements made out of steel fiber reinforced concrete while bending is determined, was conducted theoretical studies of the stress-strain state of the steel fiber reinforced concrete gutter and the engineering method of calculation of bearing capacity of steel fiber reinforced concrete gutters is developed.
