Arrow Resilient Bridge Design

June 21, 2012
2:30 – 4:00 EST

This webinar is based on the FHWA's publication titled Framework for Improving Resilience of Bridge Design (.pdf). The publication draws on the invaluable lessons from past bridge failures for improving the resilience of bridge designs by using the "fault-tree analysis" methodology to identify potential events that could lead to a bridge failure, and designs that prevent such failure.

Bridges are an integral and important part of the highway infrastructure system and need to be designed to provide the necessary safety and resiliency for the traveling public. Performing a failure analysis during design, coupled with the review of past bridge failures, can help to enhance the resilience of bridge design for safety, reliability, efficiency and sustainability of highway bridges. The objective of this webinar is to encourage the use of fault-tree analysis during design to avoid premature in-service failures. The seminar will cover the following topics:

  1. Introduction - Myint Lwin, P.E., S.E. Director, Office of Bridge Technology, FHWA
  2. Lessons from Bridge Failures – Myint Lwin
  3. Illustrative example of a fault-tree analysis of a concrete bridge – Brandon Chavel, Ph.D., P.E. Structural Engineer, HDR Engineering
  4. Illustrative example of a fault-tree analysis of a steel Bridge - Brandon Chavel
  5. Questions and Answers – All participants
