If speed is what you're after, then uncoated weathering steel (UWS) is your best choice! UWS doesn't require any applied coating--that means no time spent literally watching paint dry. NSBA's new Uncoated Weathering Steel Reference Guide is your go-to resource for using UWS in a variety of bridges in a diverse mix of environments.
Cross-frames are one of the costliest elements in a steel bridge on a per-pound basis. Lean-on bracing reduces the number and complexity of cross-frames which will have a significant impact on the speed of fabrication, speed of erection, and overall bridge cost. The new Lean-on Bracing Reference Guide shows bridge designers how to implement lean-on bracing in routine bridge designs with confidence and with minimal computational effort beyond that required for a traditional bracing system.
The Navigating Routine Steel Bridge Design guide complements the 9th Edition AASHTO LRFD Bridge Design Specifications and addresses the design of steel superstructures for routine steel l-girder bridges. It contains hyperlinked checklists that walk engineers and designers through the process, step by step, focusing on the specific provisions of the AASHTO Specifications that apply to these routine bridges.
It's here! The 2022 edition of the Steel Bridge Design Handbook (formerly known as the Highway Structures Design Handbook) is now available as a free download. The new version includes the latest research and advice from the nation's top bridge experts as well as critical information on everything from the mechanical properties of steel to splice design to corrosion protection.
Need a quick estimate for steel bridge superstructure weight? Then look no further than the NSBA's "Steel Span To Weight Curves". They are a great way to compare various span arrangements and girder spacings on the back-of-an-envelope.
