ABSTRACT
The shear resistance of bridge deck slabs without shear reinforcement is currently a decisive structural property for design of the slab thickness. The dominant shear action is represented here by the concentrated load due to the wheel contact pressure. The missing model for the shear distribution in case of a concentrated load became the major motivation for an experimental campaign and afterwards for a non-linear analysis of this phenomenon. Together 12 slabs were tested in Laboratory with concentrated load and the obtained results were used for calibration of the non-linear model. The non-linear Finite Element (FE) analysis was carried out using the ATENA software. The paper will present the obtained results and recommendations concerning non-linear modeling of bridge deck slabs subjected to a concentrated load.
