摘要

The present article is concerned with basic methods of reinforcement of continuous reinforced-concrete beam constructions.The main disadvantages and difficulties in strengthening such load carrying structures have been identified in this academic paper.There has been offered the method of reinforcement of continuous reinforced-concrete beam constructions.Besides,the authors have established the procedure of designing effective continuous reinforced-concrete beams in case of the reinforcement.The basic principle of enforcement of continuous reinforced-concrete beams is proposed in this exploratory development.This principle lies in the fact that it is necessary to find the desired span stiffness of continuous reinforced-concrete beam constructions,which would provide sufficient reinforcement in the reference section of the beams.In this case,there is no need to strengthen reference sections,which is practically impossible to do in most instances without dismantlement of the existing concrete floor slabs.For reinforcement systems designing,it is proposed to use the method of design resistance of reinforced concrete,which uses theoretically,and experimentally confirmed prerequisites and hypotheses.The calculations are made by the iteration method.There has been provided a calculation example of enforcement of continuous reinforced-concrete beam constructions using the proposed method.
