Task Group 1.5

Performance-Based Design Founded on Lessons from Bridge Failures

Mission Statement/Objectives

TG1.5 is tasked with mitigating and controlling the risk of bridge collapses by conducting in-depth analysis and assessment of available information related to bridge failures, their consequences, and root causes.

Scope & Limitation

Global Focus: The project will have a global perspective, considering bridge failures and risk mitigation measures across different regions and environments.

Types of Structures: The project will focus on various types of bridge structures, such as beam bridges, truss bridges, arch bridges, suspension bridges, and cable-stayed bridges.

Materials: The project will encompass a wide range of materials commonly used in bridge construction, including but not limited to concrete, steel, and composite materials.

The following methods will be used to achieve the mission and objectives: 

  • Conduct thorough research and analysis of historical bridge failures, including their root causes and consequences.
  • Utilize advanced engineering and analytical methods to assess the structural integrity of bridges and identify potential failure points.
  • Collaborate with industry experts, researchers, and relevant stakeholders to gather data and insights for comprehensive problem resolution.
  • Develop and implement proactive measures and recommendations to mitigate the risk of bridge collapses.

Aspects Not Covered:  The focus on risk mitigation for earthquake failures will be limited. Railway bridges, bridges collapse during demolition will be excluded from the scope of this project.

Expected Project Output

  • SED book with best practices for preventing bridge failures
  • SEI Article
  • Workshops
  • Published Database containing information about bridge failures

Start Date: November 2023
Target Date of Completion: November 2026
