State whether each of the following statements is correct, and try to correct the false statements. 1. The "Superstructure" is the part of the bridge that is responsible for transferring structural loads to the foundations of the bridge. 2. Girder (or deck) bridges are better than steel truss bridges if longer spans are required. 3. Serviceability limit states are related to loss of strength and the accumulation of damage and eventual failure under repeated loads. 4. The primary reinforcement in slab bridges is parallel to the direction of the traffic. 5. Dynamic load allowance must be considered for all types of loading listed in AASHTO HL-93 loading. 6. The design output of the empirical and traditional design methods of girder bridges must be always identical. 7. The quantity of distribution steel in slab bridge is dependant on the thickness of the slab. 8. The empirical slab design method in girder bridges was merely derived based on the flexural behavior of the superstructure. 9. In the design of an exterior strip in slab bridges, the width of the exterior strip is a function of the width of the interior strip. 10. Live load type is necessary to be known in order to design a girder bridge using the empirical design method.
