About the Collaboration
The mission of the Collaboration is to achieve quality and value in steel bridges by standardization of design, fabrication, and erection and by the sharing of resources. Through the Collaboration, steel bridge professionals work together in a spirit of cooperation and mutual respect to develop details, specifications and practices and to exchange knowledge, technology and expertise.

Register NOW for Steel Bridge Night School

AISC/NSBA’s new Night School course on steel bridge design, developed in conjunction with Purdue University consists of eight weekly webinar sessions lasting 90 minutes each (up to 12 PDHs available). The course starts Monday, June 6.

Night School takes the learning style of a traditional classroom setting and combines it with the delivery method of online webinars. The 8-session course meets weekly, allowing the presenter and attendees to dive deeper and explore concepts in greater detail than typical continuing education courses. Sessions are conducted live to allow interaction between attendees and presenters but are also available to listen to at a later date for those who register for the 8-session package. This gives the attendee flexibility to listen and learn at their convenience.

The course begins with an introduction to bridge engineering, covering topics such as bridge nomenclature and how to effectively read design drawings. Sessions become progressively more advanced, addressing topics such as AASHTO bridge design standards and load combinations. The specifics of steel in bridge construction will also be explored, as well as plate girder design and fabrication of steel. Finally, the course will cover such advanced topics as effects of curvature and skew, and design for fatigue and fracture. A full list of course titles is provided below. At completion participants will have developed a breadth of knowledge in steel bridge construction and an advanced knowledge of steel bridge design considerations.

    • Session 1: June 6 Intro to Bridge Engineering
    • Session 2: June 13 Intro and History of AASHTO Bridge Design
    • Session 3: June 20 Steel Material Properties
    • Session 4: June 27 Loads and Analysis
    • Session 5: July 11 Steel Bridge Fabrication
    • Session 6: July 18 Plate Girder Design and Stability
    • Session 7: July 25 Effects of Curvature and Skew
    • Session 8: August 1 Fatigue and Fracture Design

Each session is written and presented by experts on the topic. As stated by Bill McEleney, NSBA managing director, "this course not only suits the needs of engineers and engineering students without a bridge design background, but it also serves as a refresher course for experienced bridge designers.”

For a more detailed description of each session and to register for the course, go to www.aisc.org/nightschool.

Delaware River and Bay Authority testing Drone Inspections on Delaware Memorial Bridge

The Delaware River and Bay Authority is testing whether unmanned drones can be used to inspect the Delaware Memorial Bridge.

Officials with the bi-state agency concede drones could reduce the number of human inspectors, but also say it will make the job safer because the drones can inspect the more dangerous sections of the span.

"It might, over time," said Scott Green, DRBA executive director, regarding the possibility of drones costing jobs. "A lot of people compare drones with personal computers from a few years ago. It will require a level of change people don't know yet."

DRBA, directed by a 12-member commission evenly appointed by the governors of New Jersey and Delaware, owns and operates the Memorial Bridge, Cape May-Lewes Ferry, New Castle Airport and other transportation facilities in Delaware and South Jersey. The agency conducted its first test Tuesday afternoon as a drone captured video and images under the bridge, including its steel cable and superstructure.

Images captured by the drone will be transmitted to an operator on the ground who can view live video or still photos on a tablet.

Download the NSBA’s new Steel Span-to-Weight Curves

The latest NSBA resource, Steel Span Weight Curves, is now available for download through the NSBA website. The design aids are intended to be used during the very preliminary phases of design for evaluation of alternative framing schemes . The curves have been constructed from cost-effective conceptual solutions that NSBA has prepared. They represent the predicted pounds of steel per square foot for various span lengths and girder spacings for single spans, two spans, and three or more spans.

The weight of steel is represented in terms of square footage of bridge deck because a rough estimate of bridge deck area is typically known in the preliminary stages of design. By multiplying the value obtained from the chart by the total bridge deck area, a total steel weight is found. The designer or contractor can then consult the NSBA or a fabricator to obtain pricing to establish a preliminary estimate of superstructure cost.
