Szukana fraza: [Abstrakt = "This paper describes soil\-steel bridge with the largest span in the world. Structure is located in Ostróda \(Poland\) and it is currently in a final stage of realization. Structure was designed based on North American and Canadian standards. Steel shell is made from the corrugated structural plates with deepest on the market corrugation 500×237×9,65 mm \(UltraCor\) without any of reinforcing ribs. Single barrel of UltraCor has less stiffness then previously used SuperCor’s \(381×140×7 mm\) reinforced by EC Ribs \(mirrored plate and encased concrete\). Steel used for UltraCor has higher grade than steel used for smaller corrugation. Because of the large span ever used the control of the deformations during construction is carried out. One of the measurements are displacements used to determine the change of the radius of curvature of the shell crown point. Structures is also monitored with strain gauges giving direct view of the changes of stresses in a corrugated steel shell. The summary highlights large changes of radiuses of shell curvature and ability of determine them based on geodetic measurements – commonly used on the sites."]
