The provisions in this section apply to the design of bridge and retaining wall components constructed of normal density or lightweight concrete and reinforced with steel bars and/or prestressing strands or bars. The provisions are based on concrete strengths varying from 2.4 KSI to 10.0 KSI.
The provisions of this section combine and unify the requirements for reinforced, prestressed, and partially prestressed concrete. Provisions for seismic design, analysis by the strut-and-tie model, and design of segmentally constructed concrete bridges and bridges made from precast concrete elements have been added.
A brief outline for the design of some routine concrete components is contained in Appendix A.
