Title of the articleCalculation of the strength of reinforced concrete sleepers taking into account the joint deformation with the ground base
Abstract.Problem statement. Reinforced concrete sleepers are special structures due to complex geometry and increased requirements for their crack resistance and endurance. The necessary crack resistance and endurance is provided by the use of prestressed reinforcement. The purpose of the study is to develop methods for calculating the endurance and crack resistance of reinforced concrete sleepers with prestressed core reinforcement on the basis of theoretical studies. Results. New methods for calculating the endurance and crack resistance of reinforced concrete sleepers with prestressed reinforcement have been developed. Conclusions. The significance of the results obtained for the construction industry lies in the fact that they make it possible to more accurately assess the endurance and crack resistance of reinforced concrete sleepers with prestressed reinforcement.
Keywords.stressed reinforcement, crack resistance, endurance, reinforced concrete sleepers, creep of concrete
