Analysis of technical and operational condition of urban reinforced concrete bridge structures

The article analyzes the technical condition of urban reinforced concrete bridge structures. The authors studied the technical passports of all bridges and overpasses in Tashkent and made direct technical inspections of more than 10 bridge structures. As a result, most of the shortcomings and defects of the existing bridge structures in the city were revealed. In Tashkent, there is a significant number of reinforced concrete bridge structures, the service life of 60 to 100 years (24% of the total number), a significant part of which (42%) has been operated for many years without major repairs. A "four-level" approach is proposed, which contains four stages of analysis, and evaluates the technical condition of the operated reinforced concrete bridge structures.
