Title of the articleTheoretical basis of fatigue failure of steel reinforcement of reinforced concrete structures
Abstract.In reinforced concrete structures under cyclic loads one of the types of failure is fatigue failure of working reinforcement. Operation mode of steel reinforcement in reinforced concrete constructions is non-stationary irrespective of loading conditions in these cases determination of fatigue resistance of reinforcement requires a great number of experiments which requires a great number of financial and manpower resources. The aim of the work is to develop a theory of fatigue cracking of steel reinforcement to create design models of reinforcement with cracks, for this purpose it is necessary: to establish the scheme of fatigue crack formation in reinforcement rods for reinforced concrete structures; to develop the equation of change in specific energy of steel fracture in the zones of crack formation and development; to develop a methodology for calculating the durability of steel reinforcement with cracks.
Keywords.steel reinforcement, stress design profile, fatigue crack, damage, plastic life, specific energy, concrete creep stress, elastic work of reinforcement.
