Consider a reinforced concrete deck supported by five prestressed concrete I beams spaced at 5.2 m. The deck is 480 mm thick with 76 mm of wearing surface for a northern state. The top-flange width of the beams is 900 mm. Design the deck’s interior bay reinforcement for positive and negative moments according to the AASHTO specifications. Assume f’c = 28 MPa and fy = 420 MPa. Use 20 mm diameter reinforcements and the parapet of 13.4 kN/m acting 2.4 meters from end beams.
