Szukana fraza: [Abstrakt = "The text describes one\-span bridge over Odra canal lock in Lipki \(Lipki barrage\). The bridge is a welded steel structure with plate girders in tandem arrangement. The bridge has a span of 25,25 m and construction height of 1,148 m. The structure was erected using St3M structural steel. It was designed for a C\-class load defined in Polish Norm PN\-85\/S\-10030. Static load tests were conducted in 1993, in accordance with the requirements of PN\-89\/S\-10050. The values of the deflections measured for the beams turned out to be lower than previously calculated, and they were fully reversible. The bridge was opened for use. In 2017, due to nearby construction work and related heavy traffic, professional evaluations had been conducted. For the purpose of the evaluation a complete inventory was made, with particular focus on corruption. In addition, tests of steel samples were carried, confirming that the span was built with St3M steel, and also structural analysis of the span was made. Calculations show that the bridge satisfies the requirements of B load class defined in PN\-85\/S\-10030, higher than previously expected."]
