Abstract

The calculation methods of reinforced external reinforcement elements when working on torsion are considered succinctly in available sources and current regulatory documents. This article discusses a number of existing proven methods for calculating reinforced concrete bendable elements with external composite reinforcement, including when working with torsion. The necessity of introducing into the existing calculation dependences of the prerequisites for substantiating the behavior of reinforced concrete bendable elements, including those with external composite reinforcement, when working in a complex stress-strain state is described. The cases of occurrence of additional torsional forces in the conditions of classical variants of loads and impacts on the element are considered. A description of the work of reinforced concrete elements with external reinforcement with composite materials during bending with torsion is proposed. The main provisions of the work of reinforced concrete structures in bending with torsion are given. The main limiting states are presented. An assumptions are made about the possible presence of additional limiting states of reinforced concrete elements with external reinforcement with composite materials. A variant of the condition of proportionality of longitudinal relative deformations for reinforced concrete elements with external reinforcement with composite materials during bending with torsion is proposed.
