Blikharskyy Y. Residual resource of reinforced concrete structures with damages of thermally strengthened reinforcement

The object of the study is stress-strain state damage of reinforced concrete bent structures with damage of thermally strengthened reinforcement. The aim of the study establishment of actual stress-strain state and residual life of reinforced concrete beams depending on the degree of damage in reinforcement. Research methods: experimental research with approbation of the method of digital image correlation; probability theory, limit state method. Results: new experimental data of reinforcement class A500C with damage and reinforced concrete beams reinforced with this reinforcement were obtained; submitted in accordance with the current design standards of the proposal to determine the residual bearing capacity and residual life of such structures. The practical results can be used in assessing the technical condition of reinforced concrete structures with damage. The obtained theoretical results develop the scientific direction of determining the residual life of reinforced concrete damaged structures. Implemented in the educational process of the Lviv Polytechnic National University also at the objects of Kyiv and Lviv region.
