A 576 m long creep and shrinkage specimen – Long?term deformation of a semi?integral concrete bridge with a massive solid cross?section

For creep and shrinkage investigations, relatively small cylindrical specimens are generally exposed to constant climatic conditions. The derived mainly empirical prediction models used for the calculation of large engineering structures with massive cross-sections. In this paper, expected values material according fib Model Code 2010 Eurocode 2 compared monitoring data, which were acquired over a period more than 12 years during structural health viaduct. It was found that in addition measured continuous increase viscous deformations, seasonal fluctuations due influences could also be detected. numerical calculations show differ significantly their magnitude time course predicted concrete deformations. comparison good agreement achieved when using 2. 2010, on other hand, underestimated deformations bridge girder.
