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 industries 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.
On March 14, 2017, the National Steel Bridge Alliance will hold a lunch time (12:30pm-1:30pm CT) webinar focusing on the updates to AASHTO’s bolted splice design. In the upcoming 8th Edition of AASHTO LRFD Specification, a simplified methodology to bolted splice connections will be incorporated. Karl Frank, PhD, PE, of Hirschfeld Industries, will lead a discussion of what the changes are, how the changes will affect splice designs, and finally lead the group through three examples.
In conjunction, NSBA will release a guide document, complete with three full connection examples, to be used as reference when performing a splice design. Both will be available for free download through steelbridges.org.
|$125 for Members|
|$190 for Non Members|
|$100 for Students/Faculty|
Attendees will receive 1 PDH upon completion. Registration can be made through AISC Education website
In conjunction with AASHTO, NSBA has released two Collaboration documents for free download. The two documents join a growing list of AASHTO-approved guide documents and specification documents for use as references during the design, fabrication, and erection processes.
G12.1 - 2016 Guidelines to Design for Constructability is an update to the 2003 document of the same title. G12.1 is intended for engineers, contractors, and fabricators for use throughout the design and fabrication process as a reference document to ensure efficient and economical girder design and construction. The update features numerous changes that reflect the advancement of the industry over the past decade.
G2.2-2016 Guidelines for Resolution of Steel Bridge Fabrication Errors is a new document to address common issues that can result during the fabrication process. From a misaligned bolt hole to a miscut member this document discusses the common issues and how the errors should be resolved. Many times, the fix can be more costly and detrimental than the original error. This document provides the necessary guidance to ensure an economical fix that preserves the long term resilience of steel girders.

Infrastructure spending, and bridges in particular, continue to be a topic of discussion at the federal level. This has generated a lot of excitement in the construction community, especially when the government is talking about spending upwards of $1 trillion. While the administration is championing a $1 trillion spending package, it’s important to remember a few facts:
- The $1 trillion is factored over 10 years.
- The $1 trillion includes not just bridges but roads, dams, power distribution,schools and many other types of construction.
- Discussions of federal infrastructure spending look to be tabled until 2018, pushing the prospect for a new federal funding program out that much further.
- While the plan will provide an infusion of money, it still is not sufficient to completely meet the need of upgrading or replacing 56,000 structurally deficient bridges.
- Finally, it's anticipated that the rate of bridges becoming structurally deficient will actually increase as the population of bridges continues to age and the large inventory of post-WWII bridges begins to need repair or replacement.
The NSBA urges you to contact your representatives in Congress and support infrastructure funding as well as the extension of Buy America and Hire American provisions to all infrastructure projects funded or financed with our tax dollars and proposed tax credits.
