Resumen

Slab bridges are assessed for composite dead load (self-weight and weight of wearing surface) and live loads (distributed lane loads and concentrated wheel loads). The shear stress over the support will have a peak value, which is in practice distributed over a certain width to find the governing shear stress for comparison to the shear capacity from the code. To study the distribution width, an experiment and a finite element model were used. This comparison is used to study the shear stress distribution and the admissible distribution width in finite element results. The results of the reaction forces in the experiment are used to define the shear stress over 2dl and 4d l. It is found that 4dl can be used and leads to conservative results. These results are the first experimental evidence on the distribution width for peak shear stresses, replacing previously used rules of thumb.
