Q2. The figure below shows a deck slab needs to be designed for a bridge. If a prestressed road bridge is used with 400 mm thick with parallel post-tensioned cables, in each of which the force at transfer is 750 kN. The bridge is required to support a uniformly distributed applied load of 8+(W/600) (Last 3 digits of your id) kN/m, with tensile stress in the concrete not exceeding 0.80 N/mm at any time. Design the slab and assume 20% loss of prestress after transfer. Also calculate the number of steel wires used in each cable with the permissible stress of 1200 N/mm for 7 mm diameter steel wire. Assume the density of the concrete is 25 kN/m. 15 m WH 15 m 15 m 4.5 m 6 m
