Stress–Strain State Simulation for the Eccentrically Compressed Reinforced Concrete Columns with Local Prestress at the Manufacturing Stage
The article is devoted to columns with local prestressing of tensile reinforcement. Such columns can be used with large eccentricities of the longitudinal force, for example, in industrial buildings. Prestressing of the reinforcement in the structures under consideration is created using tension couplings. The design of columns with local prestressing is described. The derivation of resolving equations for determining the stress–strain state at the manufacturing stage is given, taking into account the nonlinear properties of concrete. The calculation model is based on the hypothesis of plane sections. The problem is reduced to a system of two equations for axial deformation and element curvature. An algorithm for the numerical solution of the resulting system is described, which is implemented in the Matlab environment. A formula for the deflection of the element at the manufacturing stage is obtained. Verification was performed by comparison with the finite element software package LIRA in three-dimensional nonlinear formulation.
