Raduga + Beta

555 Raduga v2.0.11 + Beta v4.0 build 01/25/2007 In the last decade, due to widespread computerization in the field of reinforced concrete theory, the deformation calculation model of normal sections has found practical application for the calculation of reinforced concrete elements exposed to longitudinal forces and bending moments. This calculation model includes: equilibrium equations of external and internal forces, the deformation condition of the normal design section in the form of a hypothesis of flat sections for averaged values ​​of relative deformations, and deformation diagrams of concrete and reinforcement. The system of governing equations is transformed into resolving equations, which are solved by step-iterative methods, which are based on various modifications of the method of elastic solutions as applied to concrete and reinforced concrete. The deformation calculation mo
