Comparison of operating costs of reinforced concrete bridges and overpasses with different static schemes

The article considers two options for the design of an overpass with a beam-cut and a beam-continuous static scheme. An inspection of the technical condition of beam-cut reinforced concrete bridges in operation in Tashkent built in 1970-90 was conducted. Estimating the maintenance costs of overpasses with different static schemes operating for the last 50 years shows that the continuous reinforced concrete option drastically reduces the cost of repair work in operation. This, in turn, has a cumulative effect on the development of the bridge-building industry in the Republic of Uzbekistan. The predicted operating costs of overpasses with different static schemes during operation for 50 years showed that in a continuous reinforced concrete option, 435,803,803 soums are saved annually. The most important thing is that the proposed solution dramatically reduces the cost of repair work. This, in turn, has a cumulative effect on the development of the bridge-building industry in the Republic of Uzbekistan.
