<p>The City of Wrocław has been surrounded by the highway bypass since the year 2011. There is a large cable-stayed bridge along that way across the Odra River including two main spans each 256 m long. The height of the pylon is 122 m. The deck is supported from 160 stays Freyssinet HD2000 type. Total quantity of steel in stays reached about 1500 tons. The installation of stay cables was arranged according to Freyssinet Isotension procedure, as well as the specialized equipment supplied by Freyssinet was widely used. Time period consumed for installation was extremely short, it lasted about two months. As the result a modern elegant bridge appeared enriching the landscape of Wrocław peripheries.</p>
The Rędziński Bridge in Wrocław is the biggest Polish concrete cable-stayed bridge. It is equipped with a large structural health monitoring (SHM) system which has been collecting the measured data since the bridge opening in the year 2011. This paper presents a comparison between the measured data and the finite element method (FEM) calculations, while taking into account 7 years of data collection and analyses. The first part of this paper concerns the SHM application. In the next part, which contains comparisons between forces in cables and temperature changes throughout the structure, the measured data are presented. The third part includes SHM-based calculations and simulations with a complex FEM model to check the measured data and to estimate future measurements. The last part contains a durability assessment calculation for the cable stays.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
