Abstract

In the Netherlands, many existing reinforced concrete slab bridges were built more than 50 years ago. Upon assessment with the new codes, a large number of this type of bridge rate insufficiently. Since many of these existing bridges present complex material properties and boundary conditions, proof load testing is considered an effective method to assess their capacity. However, to be able to safely apply proof load testing on slab bridges, verification in the laboratory is necessary. Therefore, experiments on reinforced concrete slabs of 5 m × 2,5 m × 0,3 m under a concentrated load with varying shear span to depth ratios are carried out in the laboratory of Delft University of Technology. Additionally, nonlinear finite element analysis is used to simulate the experiments following the guidelines of nonlinear finite element analysis published by the Dutch ministry of infrastructure and water management. The results from the finite element and experimental analyses are compared in terms of peak load, failure mode, and crack pattern. A good agreement between the experimental and numerical investigations is observed.
