Annotation: Subject matter of article is solution of actual problem which is possibility of alignment of structures in operation by welding. Change of residual stress state of structure after overlaying of welding joints is predicted by calculations. In process of evaluation of reinforced elements deflected mode are accepted standard hypotheses such as smallness of lateral deformations influence assumption and flat sections hypothesis. Experimental research of work of elements reinforced under load helped to define that deviations from linear law of deformations distribution are found in zones which are directly adjacent to welding joints. Small length of mentioned zones in comparison with section dimensions allows usage of flat section hypotheses in practical calculations. Special feature of reinforced elements calculations is need for modeling reinforcement technology because it significantly influences on reinforced structures work. Numerical calculations help to receive solutions for particular tasks only by specified parameters of system, initial and limit conditions of system and particular work execution technology.
Keywords: operation of structures, residual deflection, alignment by welding, prediction of residual stress state, technology.
