description: The objects of research are concretes for the construction of prestressed structures, as well as bent and off-center compressed elements.
The aim of the work is determine the main deformation characteristics of a reinforced concrete rod element working on a bend, including a secant modulus of elasticity, which takes into account both elastic and residual deformations at stresses above 0.4-0.5 R, as well as correcting the diagram of concrete work with creep for nonlinear calculations.
The methodology of the research is to conduct parallel experimental studies, determine the main deformation characteristics during long-term loading of prism samples using the classical method in compression mode and beam samples using the proposed method in the "bend" mode.
The relevance of the developed method lies in the ability to conduct creep tests without using complex spring installations available to only a few scientific organizations, which significantly reduces labor costs. This capability is planned to be achieved by obtaining a transition coefficient from the creep of concrete in the "bend" mode to the creep in the "compression" mode.
The result of the work was the obtained data of physical and mechanical, deformation and rheological characteristics of concrete, including creep deformations in the "bend" mode, which are necessary for further research and updating of regulatory documents.
