Dyachenko E. Calculation of strength of reinforced concrete elements under biaxial bending in view of the full diagram of a physical condition of concrete

Subject - reinforced concrete beams under biaxial bending; object - develop method of calculation of strength in normal section of reinforced concrete elements under biaxial bending on the basis of deformation model; procedures - experimental researches in laboratory conditions and the theoretical researches based on methods of mathematical modeling; theoretical results - for the first time simple analytical dependences for definition of limiting values deformation of concrete of the compressed zone in structure of reinforced concrete elements under biaxial bending depending on the form of the compressed zone for an optimum case of reinforcing are received; limiting values of deformations of concrete in structure of reinforced concrete beams are experimentally confirmed; the level of form of the compressed zone influence on limiting deformations of concrete is theoretically established and experimentally confirmed; advanced a method of calculation of strength in normal section of reinforced concrete elements under biaxial bending in view of deformation model on the basis of use of the full diagram of a condition of concrete and dependences for definition of limiting deformations of concrete; results - the method of calculation of strength in normal section of reinforced concrete elements under biaxial bending on the basis of deformation model is offered; the dependences received in the dissertation, allow to define optimum quantity of armature in reinforced concrete elements under biaxial bending; branch - constructional engineering.
