Abstract
Introduction. The experience of operation of reinforced concrete span structures of bridges from the time of their use shows the need for their constant improvement. Due to the use of pre-tensioning of reinforcement in reinforced concrete span structures of bridges, it was possible to increase the crack resistance of such structures and operational reliability. This is especially relevant when it is necessary to increase the length of spans of reinforced concrete span structures. Problems Statement. The use of monolithic prestressed span structures with tension on concrete (post-tensioned systems) is the newest for Ukraine. They have many advantages compared to prefabricated prestressed reinforced concrete. But it is necessary to solve a number of problems in the design and construction of such structures in order to achieve the efficiency of structures that would serve the designed term, using all their advantages. Therefore, the study of such structures, assessment of their stress-strain state will allow in the future to find solutions for their improvement, development of appropriate calculation recommendations, construction of such structures. Purpose. Study of the stress-strain state of the structure of the monolithic non-separated prestressed span structure of the overpass with tension on concrete (post-tensioned system) in the city of Kherson.
