ABSTRACT
Abstract In-situ measurement on structures are often the basis of improving the model underlying the calculation of stresses in the structural elements. At an oblique-angled steel-bridge of the Metropolitan Railway of Berlin (S-Bahn), we observed a crack at a secondary structural element, a splice plate for fixing main girders at a joint. The element suffered no stresses if using a simplified system for the stress analysis. On the basis of more sophisticated models, the stressing of the plate could be calculated, adapting the model to the real behaviour by strain measurement results.
