Abstract
The method of calculating the strength of compressed elements according to the deformation model, taking into account the operation of compressed composite polymer reinforcement, is described. The criteria for the strength of the normal section of the compressed element are proposed when calculating according to the deformation model using piecewise-linear and curved diagrams of axial compression of concrete. The comparison of the results of calculating the strength of prototypes according to the deformation model with experimental data and with the results of calculations using the method of limiting forces is given. It is shown that the proposed method for calculating eccentrically compressed elements, taking into account the work of composite reinforcement in compression, leads to satisfactory convergence with experimental data when using both piecewise linear and a curvilinear diagrams of the axial compression of concrete. By comparing the strength calculation results of the considered sample of experimental non-centrally compressed samples made according to the deformation model using a curved diagram and the method of limiting forces, their satisfactory coincidence was established.
