Abstract

The article considers the definition of short-term and long-term stiffness of reinforced concrete elements that bend. For the calculations, elements that are strengthened by the build-up are taken. The reliability of the recommendations of I.I. Ulitskyi is substantiated by a numerical experiment. According to the approximate definition of short-term and long-term stiffness of reinforced concrete elements that bend. Calculation formulas are recommended for determining the stiffness of bending elements strengthened by building up. It has also been proven that the formulas for determining the stiffness of elements reinforced by top and bottom reinforcement are suitable for use in calculations.
