This chapter deals only with piers or columns for conventional bridges, such as grade separations, overcrossings, overheads, underpasses, and simple river crossings. Reinforced concrete columns will be discussed in detail while steel and composite columns will be briefly discussed. Substructures
selection and the design and detailing of multi-column piers, single column piers, pile bents, straddle bents, and integral pier caps. Lastly, this chapter briefly discusses substructure design software, seismic design, precast substructures, soil-structure interaction, and superstructure-substructure interaction. 9. Keywords
this module provides an overview for the structural analysis of steel girder bridges. Discussions include the applicable loads, descriptions of the various tools and techniques available, and considerations for selecting the appropriate application or technique for a given bridge. 9.

Steel bridge fabrication is a field unlike any others such as building construction, therefore most detailers who prepare steel bridge shop drawings specialize in bridges, and very few of them detail buildings or other steel structures.
The primary function of a bridge deck is to support the vehicular vertical loads and distribute these loads to the steel superstructure. This chapter provides practical information regarding the decking options and design considerations for steel bridges, presenting deck types such as concrete deck slabs,
columns, towers, abutments and retaining structures, geotechnical considerations, footing and founda- tions, vessel collisions, and bridge hydraulics. The Handbook stresses professional applications and practical solutions.
railway bridges is a safe and reliable structure that can be constructed and maintained with minimal disruption to railway passengers and traffic – steel railway bridges meet these requirements particularly well.
