An elevation view of a typical bridge is shown in Figure 10.1. A bridge structure is divided into an upper part the superstructure which consists of the slab the floor system and the main truss or girders and a lower part the substructure which are columns piers towers footings piles and abutments. The superstructure provides horizontal spans such as deck and girders and carries traffic loads directly. The substructure supports the horizontal spans elevating above the ground surface. In this chapter main structural features of common types of steel and concrete bridges are discussed. Two design examples a two-span continuous cast-in-place prestressed concrete box girder bridge and a three-span continuous composite plate girder bridge are given in the Appendix. 1999 by CRC Press LLC 1999 by CRC Press LLC bridge length FIGURE 10.1 Elevation view of a typical .
