Situation 1. A prestressed deck-girder bridge is to be constructed to cross a river stream as shown in Figure 1a. The bridge is to be designed to have a 15.6-m effective span and a 6.0-m clear width supporting a reinforced concrete slab that has a thickness of 150 mm with a 20 mm wearing surface (0.72 kPa) on top of the slab (refer to Figure 1b). The concrete slab is to be supported by three concrete girders with dimensions of 400 x 800 mm. Assume that the bridge span is a simply supported beam and unit weight of concrete is equal to 23.5 kN/m°. Interior girder dead load calculations: 1. Calculate the total uniformly distributed dead load (in kN/m) that the interior girder is carrying.
