While the main focus of the Steel Bridge Design Handbook is the design of steel girder superstructures, the overall design process associated with the design of substructures is equally important. This module provides an overview of many issues associated with substructure and foundation design. Many factors influence the selection of substructure and foundation materials, types, configurations, positions, and orientations. Often, existing constraints will limit the range of options and intrinsically lead the designer to only one or a few feasible solutions. This module provides designers with an overview of several foundation types including shallow foundations such as spread footings, and deep foundations that utilize piles or drilled shafts. The module also discusses conventional, integral, and semi-integral abutments, and provides considerations for the design and detailing of these substructure components. Several considerations for pier selection are also presented, including multi-column piers, single column piers, pile bents, straddle bents, and integral pier caps. Lastly, this module provides designers with information regarding substructure software availability, seismic design, precast substructures, and superstructure and substructure interaction.
