Revisiting Redundancy of Steel Bridges
Learning Objectives:
- Identify key changes to the NBIS as they relate to the redundancy of steel bridges.
- Explain the essential components of risk.
- Describe the basic concepts of two modes of redundancy recently adopted into the new NBIS.
- Determine the differences in the traditional method of bridge inspection as compared to a risk-based inspection program.

Purpose statement:
This course will review how the changes to bridge inspection programs and accepted methods of steel bridge redundancy brought about by the release of NBIS can impact your projects.If you are like most in the steel bridge community, you understand the guidelines of bridge design and construction. But did you know that this year, the Federal Highway Administration released a new National Bridge Inspection Standard (NBIS) with significant changes to bridge inspection programs and accepted methods of steel bridge redundancy?
This webinar will review how the changes can impact your projects. It will also explore the analytical framework needed to revisit the way we evaluate redundancy in steel bridges by considering system level and member level redundancy for new or existing bridges.
