Task Group 1.5
Performance-Based Design Founded on Lessons from Bridge Failures


Participate to the population of the Bridge collapses database!

Task Group 1.5 of IABSE Commission 1 is developing the Bridge Collapse database (BC Database) using data relevant to bridge collapses all over the world.


The BC Database will provide practical engineers with a tool they can use in their common practice. Technical information related to root causes of bridge collapses will help to identify typical failure mechanisms, to improve computational models and ultimately to better manage risk, reducing economic and social losses.

The development of an extensive and complete database is essential to this aim.


Contributing is easy:

  • You download the files below and fill the excel sheet. Instructions are provided in the pdf file
  • You send the file filled with your contribution to Andrey Sizikov (bridgeconst@gmail.com)

Data Collection Procedure

Bridge Failures Database template


We will check your contribution and update the BC Database accordingly.


As a reward for your collaboration, in 2022 you will receive access the completed database through IABSE.


Thank you very much for your help and, if you are interested in our activities, just let us know, and we will be in touch!



Mission Statement/Objectives

TG1.5 has for mission to mitigate and control the risk of collapse of bridges in designing and long term Life Cycle planning throughout the process of an in depth analysis and assessment of the available information regarding failures and their consequences.


Scope & Limitation

Collapses, partial collapses and near failures of road and foot bridges. All types of structures and materials in designing activity and long term Life Cycle planning. All regions of the world.  By using documents in open access only.


Expected Project Output
  • Global database for bridge failures (2019)
  • Special sessions or workshops during IABSE conferences
  • Technical Report with recommendations for design of bridges (end of 2021)
  • Report “Case Studies” (2022)
  • Joint research projects with other organisations (by the end of 2022)


Start Date: September 2017
Target Date of Completion: October 31, 2022
