The transition zone of the road bridges is located right behind the abutment. Function of this structure is to ease the vehicle transition from the bridge on the rigid support to the embankment with much smaller subsoil stiffness. Very important element of the transition zone structure is the approach slab. It is the reinforced concrete slab, which by its longitudinal span overcomes the uneven settlement of the bridge abutment and the embankment. This paper is focused on the shear forces caused by traffic loads represented by uniform distributed load (UDL) and tandem systems (TS) according to European standards. The results from the model with spring area support are also compared with conservative model.
