Steel Bridge Design: Substructure Design

This course provides discussions on 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 course provides an overview of various foundation types including both shallow foundations (such as spread footings) and deep foundations (such as those utilizing piles or drilled shafts). Also presented are considerations for the design and detailing of conventional, integral, and semi-integral abutments, as well as considerations for pier selection and the design and detailing of multi-column piers, single-column piers, pile bents, straddle bents, and integral pier caps. Additionally, this course briefly discusses substructure design software, seismic design, precast substructures, soil-structure interaction, and superstructure-substructure interaction.
