Bridge failures analysis as a risk mitigating tool

摘要

The research background as a database of bridge failures was created by author at the place of main work in 2006 - 2015 for improving design. Since 2015, an initiative to collect and analyse data on failures and collapses of bridges was continued by Working Commission 1 of IABSE, since 2017 - by the Target Group 1.5. Forfurther study, the information concerning highway and pedestrian bridges collapsed over last 52 years was selected. The consequences for human life and health were defined at the rate of fatalities and injured persons. Also the types of crucial human errors or other force majeure, hazards and causes were analysed. The tendency of failures number increasing correlating with operating life cycle period was revealed. The ways of future TG1.5 research activity development are outlined aiming to the relevant risks mitigation. Some proposals for the risk management measures are presented.
