Abstract
It is proposed a computational model for the spatial cracks formation of the first, second and third types in reinforced concrete structures under the action torsion with bending, based on working assumptions and solving equations, with allowance for physical nonlinearity, deplaning cross sections, prestressing in the longitudinal and transverse reinforcement and the influence of the local stress field. Solving equations are constructed in a special way, so that their system does not become decaying for functions of many variables with the Lagrange multipliers use for finding the minimum generalized load corresponding to the spatial crack formation of the first, second and third types and the coordinates of their formation points. It is obtained experimental data for checking the proposed design model, including the values of the general crack-forming load, the coordinates of the points of crack formation along the axes (x; y, z); cracks and angles of their tilt; distance between cracks at different levels of cracking; the width of the opening of the spatial cracks along the entire helical-shaped line; angles of twisting, deflections, deformation of concrete and reinforcement.
