Resumen

For the evaluation of existing slab bridges in the Netherlands, the governing shear stress resulting from composite dead load and live loads is determined from a finite element model. It is necessary to determine over which length (expressed as a multiple of the effective depth) the peak shear stress can be distributed for comparison to the design shear capacity.To answer this question, a numerical model is compared to an experiment. A continuous reinforced concrete slab, representing a half-scale slab bridge, is tested under a concentrated load. The support consists of 7 bearings equipped with load cells, measuring the reaction force profile, that can be compared to the stress profile determined in the finite element model. The comparison of measured reaction force profiles over the support to finite element models results in a research-based distribution width that replaces the rules of thumb that were used until now.
