Perlova O. Bearing strength, rigidity and strain of reinforced concrete elements with mixed reinforcement

Thesis is devoted to development of computation method for determination of durability, inflexibility and strain of the bending reinforced concrete elements with mixed reinforcement, including increased by gluing of external reinforcement, on the basis of the real concrete and armature strain diagrams. The complex of experimental investigations of work of concrete and reinforced concrete constructions increased by gluing of external metal and non- metal reinforcement or impregnation by polymer materials were performed. After the got results computation preconditions are formulated and design relations for estimation of the stress-strain state and determination of bending reinforced concrete elements with mixed reinforcement are developed, the algorithm of computation is made up, estimation of exactness of computations is executed. Keywords: concrete, metal reinforcement, non-metal reinforcement, mixed reinforcement, gluing, impregnation, strain diagram, stress-strain state, inflexibility, bending, exactness.
