“…The goal of the research is to define stop criteria for flexure and shear, so that shear assessment of slab bridges can be carried out. A number of proof load tests have already been carried out: on viaduct Vlijmen‐Oost, Halvemaans Bridge, Ruytenschildt Bridge (which was proof loaded and then tested to failure), the viaduct Zijlweg, and viaduct De Beek . A photograph of a proof loading setup can be seen in Figure .…”

Funding informationDutch Ministry of Infrastructure and the Environment.Many existing reinforced concrete bridges in The Netherlands are suspected of having insufficient shear strength, hence a methodical approach is necessary to assess them. The aim of this paper is to provide a structured approach for assessment of the reinforced concrete slab bridges, which make up a considerable proportion of the Dutch bridge stock. The proposed method uses the levels of approximation introduced in the fib Model Code for Concrete Structures 2010. The recommendations at all levels are linked to experimental research. The different levels include spreadsheet-based calculations (the "Quick Scan"), linear finite element models, nonlinear finite element models, the analysis of a structure with cracked concrete, and, for exceptional cases, proof loading of the structure. The result of this approach is a structured method of levels of assessment that can be used when many bridges need to be assessed. For most bridges, assessment at the lowest level will prove sufficient. For a limited number of cases, higher levels of assessment will offer options and guidelines for a more in-depth study of the structure being assessed.

The bridges that were built at this time are reaching the end of the service lives originally envisaged, but replacing all these structures is not practical. The economic cost of replacing these structures is high, as are likewise the ecological cost (associated with the CO 2 emissions in the production and transportation of the materials) and the social cost (such as traffic delays, which lead to large indirect costs in a densely populated country like the Netherlands). numerous reinforced concrete slab bridges that were built without shear reinforcement in the Netherlands need to be assessed with regard to their shear capacity. The scope of this study covers 600 reinforced concrete solid slab bridges, most of which were built during the 1960s and 1970s. | Levels of approximationThe recently published fib Model Code for Concrete Structures 2010 6 allows the shear and punching capacities to be calculated for different "levels of approximation."

“…The load testing and testing to failure of the Ruytenschildt Bridge (see Figure e) in Summer 2014 were fully organized by Delft University of Technology. The Ruytenschildt Bridge was a five‐span reinforced concrete solid slab integral bridge with a skew angle of 18°. Because the bridge was scheduled for demolition and replacement for functional reasons (providing a larger clearance height for the boats passing underneath), it was selected for research purposes.…”

“…Stop criteria are criteria based on the measurements, which indicate that irreversible damage is inflicted onto the structure, and that further loading is not permitted. Over the past two years, proof load tests have been carried out on the viaduct Vlijmen-Oost , on the Halvemaans Bridge in Alkmaar, on the Ruytenschildt Bridge (Lantsoght et al, 2016), which was not only proof loaded but also tested to failure, and on the viaduct Zijlweg (Koekkoek et al, 2015). The results of these load tests are analyzed and will form the basis for a Dutch guideline on proof loading of bridges.…”
