Designing a Single-Way Metal Crossing for Railway Transport

One of the most characteristic aspects of our time is the continuous development of a network of permanent communication routes. Transport links provide for the needs of industry, agriculture and trade, contribute to the international division of labor and rapprochement between countries and peoples. In this regard, it is necessary to build a large number of the road, railway, as well as the city bridges. Along with reinforced concrete bridges, which have recently become especially widespread, metal bridges are being built, which make it possible to block large spans most quickly and effectively. The development of metallurgy, the continuous improvement of the quality of construction steels and the improvement of methods for the manufacture of metal structures provide all the conditions for the successful and economically justified use of metal in the construction of bridges. Metal bridges have great production advantages due to their industrial manufacture, as well as the wide possibilities of quick mechanized assembly and installation of the structure in place. The need to save metal and reduce labor intensity in the manufacture and installation of span structures are closely related to the creation of advanced structures that meet all the requirements of operation, as well as today’s technology for mass production at the bridge structure factories. The paper presents the design results of a single-track railway bridge, analyzes the location of the designed bridge. Three versions of the bridge crossing over the river were considered, the main structural elements of the bridge crossing were developed. The authors designed the main structural solutions of joints and abutments of elements.
