scope:

These recommendations, reported by the joint ACI-ASCE Committee 343 on Concrete Bridge Design, provide currently acceptable guidelinesfor the analysis and design of reinforced, prestressed, and partially prestressed concrete bridges based on the state of the art at the time of writing the report. The provisions recommended herein apply to pedestrian bridges, highway bridges, railroad bridges, airport taxiway bridges, and other special bridge structures. Recommendations for Transit Guideways are given in ACI 358R.

The subjects covered in these recommendations are: common terms; general considerations; materials; construction: loads and load combinations; preliminary design: ultimate load analysis and strength design; service load analysis and design: prestressed concrete; superstructure systems and elements; substructure systems and elements; precast concrete: and details of reinforcement.

The quality and testing of materials used in construction are covered by reference to the appropriate AASHTO and ASTM standard specifications. Welding of reinforcement is covered by reference to the appropriate AWS standard.
