Shear capacity of slabs close to supports - Overview of experiments

The shear capacity of many of the existing reinforced concrete solid slab bridges in The Netherlands is subject to discussion due to the higher traffic loads and lower prescribed shear capacities in the recently implemented Eurocodes. However, the code provisions do not take into account beneficial mechanisms such as transverse load redistribution in slabs. Research was needed to understand the behavior of reinforced concrete slabs under concentrated loads close to supports. For this study, experiments on slabs and beams were carried out. The experiments showed that slabs under concentrated loads in shear have a larger capacity than beams. This implies that a higher capacity can be contributed to slab bridges upon assessment, so that less bridges will be identified as needing further study.
