National Steel Bridge Alliance
Registration Closing Soon for Fall Collaboration Meeting
The next AASHTO/NSBA Collaboration meeting will be in Savannah, Ga., starting October 31 and running through November 2, 2017. In addition to the usual task group meetings, the Collaboration will be joined by the AASHTO T-17 committee. T-17 has rebranded as the Fabrication of Metals Committee and will begin meeting with the Collaboration for their mid-year meeting. The schedule of meetings for the 3 days is outlined below.
Special events will take place throughout the 3 days in celebration of the Collaboration’s 20th anniversary. Starting on Halloween, join us for a walking Ghost Tour through historic downtown Savannah. The following day a short ceremony will take place during the evening dinner. Registration for each event is requested to ensure accurate attendance.

About the Collaboration
The AASHTO/NSBA Steel Bridge Collaboration is a joint effort between the American Association of State Highway and Transportation Officials (AASHTO) and the National Steel Bridge Alliance (NSBA) with representatives from state departments of transportation, the Federal Highway Administration, academia, and various industry groups related to steel bridge design, fabrication and inspection. The mission of the Collaboration is to provide a forum where professionals can work together to improve and achieve the quality and value of steel bridges through standardization of design, fabrication and erection.
Introduction to Steel Bridge Design, is back for a second run - this time during the day! Written and presented by a group of experts in the steel bridge industry, this webinar series suits those new to steel bridge design and also serves as a good refresher for experienced bridge designers.
The Series will be presented as four live webinars, beginning October 12, on topics including the fabrication process of steel plate and box girders, plate girder design, the effects of curvature and skew, and fatigue and fracture design. Four additional webinars also will be available prior to October 12 for those looking for a refresher on topics such as basic bridge terminology, the AASHTO LRFD Bridge Design Specifications, steel material properties, and loads and analysis.
You have two registration options: individual live webinars or an 8-webinar package. Purchasing individual live webinars is great for groups because registration fees cover an unlimited number of individuals at one site connection, allowing everyone present to receive a PDH certificate. The 8-webinar package allows for a single registered individual to receive a PDH certificate at a cost savings versus individual registration.
Either package of the webinar series is great for anyone looking to accelerate their proficiency in steel bridge design. From current college students and recent graduates to seasoned professionals, everyone has the opportunity to learn something new and increase their knowledge of steel bridge design.
For additional information and to register visit the AISC Continuing Education webpage.
The Prize Bridge Competition, a prestigious industry awards program organized by the National Steel Bridge Alliance, honors significant and innovative steel bridges constructed in the United States. All award-winning bridges must be built of domestically fabricated structural steel and located in the United States (defined as the 50 states, the District of Columbia, and all U.S. territories.) Eligible bridges must have been completed and opened to traffic between May 1, 2015 and September 30, 2017.
A panel of judges from the design and construction community will select winners based upon the following criteria: innovation, aesthetics, economics, design and engineering solutions. Quality of submitted presentations, though not a criterion, is important. Entries may be judged in more than one category, but an entry can only receive one award.
Winners will be notified shortly after judging and we will make a public announcement of the winners in Modern Steel Construction magazine. Designers of the winning Prize Bridge entries will be presented with plaques and honored during the World Steel Bridge Symposium. Owners of the winning Prize Bridge entries will be presented with plaques and honored at the NSBA networking event during the 2018 AASHTO Subcommittee on Bridges and Structures.
- Major span - one or more spans greater than or equal to 400 ft.
- Long span - Longest span equal to or greater than 250 ft but less than 400 ft.
- Medium span - Longest span equal to or greater than 140 ft. but less than 250 ft.
- Short span - No single span greater than 140 ft.
- Movable span
- Reconstructed - Having undergone major reconstruction, rehabilitation, or widening
- Special purpose - Bridge not identifiable in one of the above categories including pedestrian, pipeline, and airplane
In addition to the above categories; NSBA will also offer special commendation to projects that best exemplify Accelerated Bridge Construction, and a full range of Sustainable attributes.
All entries are due by 11:59 pm, December 8, 2017.
On December 6, join the NSBA for a preconference workshop on the recent developments in steel accelerated bridge construction. The 4 hour seminar will focus on the latest design tools and technology. Included, will be presentations on the advancements in assembly and erection of steel bridges, case studies on optimizing girder designs, and changes to the design of bolted splices as adopted in the AASHTO design specification.
Pre-conference registration closes November 17. Onsite registration will be available. For additional information and to register, click here.
Corresponding with changes made in the 8th Edition AASHTO LRFD Design Specification, the NSBA has released new guidance on bolted field splice connections. In the forthcoming Specification the design of bolted field splices has been simplified in an effort to generate more efficient and economical bolted connections. Complementing the 8th Edition Specification, NSBA’s document Bolted Field Splices for Steel Bridge Flexural Members provides a walkthrough of the updated design procedure as well as three complete design examples for typical plate girders, deep plate girders, and tub girders.
Additionally, NSBA’s Splice has been completely retooled. The new version of Splice is presented in an easy to understand Microsoft Excel spreadsheet format allowing users with Microsoft Excel 2010 or later to access and utilize.
NSBA Splice takes the time consuming task of designing and checking a bolted splice connection and makes the process simple with a straightforward input page and easily understandable output page.. NSBA Splice can be incorporated as a design tool on plate girder bridges allowing the designer to quickly analyze various bolted splice connections to determine the most efficient bolt quantity and configuration. Splice allows the user to explore the effects of bolt spacing, bolt size, strength, and connection dimensions on the overall splice design.
Included in the download is the design spreadsheet as well as two complete examples. The examples are the inputs and solutions for Examples 1 and 2 presented in Bolted Field Splices for Steel Bridge Flexural Members
