Abstract
A method is proposed to restore the operational suitability of bent reinforced concrete structures with increased deflections and excessive crack opening. Modern methods of reinforcement by surface gluing composite fibro-reinforced plastics (FRP) on the stretched zone of exploited reinforced concrete structures increase the strength and rigidity of reinforcing elements, but do not reduce deflections and the width of crack opening. To restore the operational suitability of damaged reinforced concrete structures, a preliminary stress is proposed, which is used to strengthen FRP, which is provided by the creation of a temporary construction lift in the damaged elements.
