Savytskyi O. Strength and condition assessment of the operated reinforced concrete bending structures, by the results of non-destructive loading

Research object - operated bending reinforced concrete structures; purpose - development of method for strength estimation of a cross section normal to the longitudinal axis and method for condition assessment of operated bending reinforced concrete structures based on the results of non-destructive loading; techniques - theory of reinforced concrete structures resistance, standard methods of concrete and reinforcement physical and mechanical properties investigation, experimental reinforced concrete investigation methods, numerical simulation, probability theory and mathematical statistics, similarity theory; results - developed general provisions, method and analytical model, that allow strength estimation of the cross sections normal to the longitudinal axis of operated bending reinforced concrete structures on the basis of the test loading without destruction; obtained strength estimation results of cross sections normal to the longitudinal axis of the bending reinforced concrete structures with different reinforcement percentage in laboratory conditions, as well as bending reinforced concrete structures of real objects; proposed a method for technical condition assessment of bending reinforced concrete structures based on the results of numerical simulation; implemented - in estimating strength of reinforced concrete building structures in Dnipropetrovsk and Kaliningrad; in the preparation of master's degree works; in the development of regulatory and technical documentation.
