Steel Bridge Essentials Webinar Series Available On-Demand
The NSBA, Short Span Steel Bridge Alliance (SSSBA), and University of Wyoming hosted a six-part webinar series featuring a distinguished panel of industry experts that provided educational information on topics essential to the design and installation of steel bridges. The recorded webinars from June 2021 are now available to view on-demand.
NSBA Guide to Navigating Routine Steel Bridge Design
AASHTO LRFD Bridge Design Specifications, 9th Edition This guide is intended to complement the AASHTO LRFD Bridge Design Specifications (AASHTO LRFD BDS) and addresses the design of steel superstructures for "routine steel l-girder bridges." It illustrates which provisions of the AASHTO LRFD BDS are applicable to the design of these types of structures, and perhaps more importantly, which provisions are not applicable or are only partially or conditionally applicable.
If a given bridge somehow falls partially outside the limits of the definitions of a "routine steel l-girder bridge" or outside the exclusions of this scope, this guide may still provide value to designers. The purpose of this guide is to help engineers streamline the design process, avoid unnecessary or misguided effort, and simplify their approach to the necessary tasks associated with the design of a more routine steel l-girder bridge.
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.
