Diagnostic Survey of prestressed concrete bridges in Prague
Original language description
The article focuses on a comprehensive analysis of prestressed road bridges in the administration of the Technical Administration of Communications of the Capital City of Prague. Prague (TSK) in the Czech Republic. Most of the structures were mainly built between the 1960s and 1980s, mainly various types of prefabricated structures. The project evaluated the diagnostic surveys and load capacity calculations carried out so far on several dozen constructions. Detailed diagnostic surveys, which are carried out according to methodological standards and include visual inspections, laboratory and chemical analyses of the concrete, carbonation measurements, chloride concentration determinations, as well as direct inspection of the condition of the prestressing reinforcement, including endoscopy of the tendon ducts, play an essential role in the evaluation process. The paper summarizes and statistically evaluates the findings obtained from the analysis of superstructure made of I-73 Girders and gives an overall view of the condition of these bridges, with emphasis on the estimation of the residual service life and possible rehabilitation measures to increase their reliability and extend their service life.
