SAVE THE DATE: Spring AASHTO-NSBA Collaboration Meeting

The spring 2017 AASHTO-NSBA Collaboration meeting will be held May 2-4, 2017 in Denver. The meetings are tentatively scheduled to be held at the downtown Crowne Plaza hotel with registration and meeting schedules available in early 2017. You can stay up-to-date on the latest information by registering to receive the NSBA Newsletter.

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.


 Nucor’s Purchase of Longview Steel Mill adds to HPS Capabilities


Earlier this year Nucor completed the purchase of Joy Global Inc’s. Longview, Texas steel mill, renaming it Nucor Steel Longview. The new facility is Nucor’s second mill capable of producing plate products for the bridge market. Longview specializes in high value-add steel and will add approximately 180,000 tons to Nucor’s overall plate capacity. Specifically for the bridge market, Longview adds to Nucor’s capabilities to produce A709 grades HPS 50W, 70W, and 100W steel.

The Longview plant utilizes the Quench and Temper (Q&T) heat treatment process, which allows for HPS plate to be produced in greater thicknesses and widths. This process complements Nucor Hertford County’s capabilities for producing HPS plate where the max plate thickness is 2".

HPS 70W steel has seen growth in markets where long spans are necessary or depth limitations represent a boundary constraint. Each of the plate mills that can supply steel for the bridge market have their own production limitations. For a complete summary of HPS dimensional limitations check out the table below.

As the NSBA suggests in the 2011 MSC article “Steel Plate Availability for Highway Bridges” historical experience suggests that cost can be minimized by specifying plate sizes that overlap with each mill’s production capabilities.

Maximum Plate Dimensions for HPS70W Steel

*Note: Maximum values are independent of each other. A maximum in one category does not correlate to a maximum in another category. This is due to plate piece weight limits. Consult steel mill capability tables for specific dimensions.


 NASCC Registration opens December 12 but the Advance Program is out Now!

North American Steel Construction Conference (NASCC) registration opens in less than one month (December 12, 2017) with this year’s conference featuring a full bridge track. Back once again will be the ever popular presentations on fracture critical. Rob Connor, Ryan Sherman, and Matt Hebdon will continue the discussion on current and future fracture critical policies as well as present ongoing research that will hopefully result in fewer bridges being classified as fracture critical. New topics at this year’s conference include two presentations on AASHTO’s updates to the 8th Edition Specification and a presentation on steel bridge erection. As always, numerous successful bridge projects will be discussed and examined, including the New Tappan Zee Bridge. An engineer attending every bridge session has the opportunity to receive up to 16 continuing education credits, enough to satisfy over half of the required hours in most states.

For a complete listing of topics at the 2017 NASCC view the Advance Program. To stay up-to-date on the latest NASCC news visit www.aisc.org/nascc and subscribe to the NSBA Newsletter.

What is NASCC?
NASCC: The Steel Conference is the premier educational and networking event for the structural steel industry, bringing together structural engineers, steel fabricators, erectors and detailers. The Steel Conference offers more than 130 sessions on topics ranging from “Practical Advice for Reviewing Software Generated Connection Designs” to “Lateral Torsional Buckling and its Influence on the Strength of Beams” to “Keeping OSHA out of your Bank Account.” In addition to practical seminars on the latest design concepts, construction techniques and cutting-edge research, the conference also offers an extensive trade show, featuring products ranging from structural design software to machinery for cutting steel beams, as well as plentiful networking opportunities. And one low registration fee gains you access to all of the technical sessions, the keynote address, the T.R. Higgins Lecture and the exhibition hall.
