Abstract
Introduction. This paper presents the results of experimental and theoretical studies of reinforced concrete cylindrical elements in a triaxially stressed state.
Aim. The main objective of this work was to analyze experimental data on the influence of various structural and force factors on the stress-strain state of prestressed reinforced concrete elements in a triaxially stressed state at all stages of their operation, as well as to develop a methodology for their calculation.
Materials and methods. The materials of previously performed experimental studies on prestressed reinforced concrete samples of cylindrical shape with stressed wire reinforcement wound along the side surface were used. The calculations were performed by the finite element method in a physically nonlinear formulation using the ATENA software package.
Results. The analysis of experimental data on the effect on the bearing capacity of cylindrical samples of the ratio of their geometric dimensions, concrete strength, degree of lateral compression. The features of the nature of deformation under load of samples in the cage, their behavior during repeated loading are considered. Computational finite element modeling of the operation of triaxially loaded cylindrical slabs at all stages up to destruction is performed, the results obtained and comparison with experimental data are presented.
Conclusions. Recommended values of geometric and force parameters have been determined, providing the most rational design solutions for thick slabs operating in a triaxially stressed state. A method for calculating such structures has been developed.
