Abstract
Purpose. Improving of construction of reinforced concrete span structures for small and medium railway bridges. Methodology. To achieve the aim, modern designs have been considered and international experience of designing of reinforced concrete span structures has been analyzed. Findings. The research of actual normative documents, the current state of structures and technologies in the field of construction and major repair of small and medium span structures has been carried out. The improved construction of reinforced concrete span structures, which avoids the main problems that appear during the operation in structures of the existing construction has been developed. Originality. The new concept of external reinforcement of concrete span structures has been proposed. Reinforcement and formwork drawings of reinforced concrete span structures of railway bridges has been improved. Practical value. The proposed solutions allow to solve a number of problems that related to the production and exploitation of reinforced concrete span structures of railway bridges.
