Advancing Bridge Sustainability: Workshop on Long-Term Indirect Monitoring

Uncategorized

•  Date: June 19, 2024 (Wednesday)     • Time: 13:00-17:30

•  Venue: U9, Otakaari 1 (2nd floor), Aalto University, Finland

Scope: Bridge structures play a vital role in supporting economic growth and enhancing citizens’ quality of life. Monitoring the health conditions of bridges throughout their service life is essential for ensuring sustainable bridge management. However, the conventional approach of employing direct structural health monitoring with sensors directly on bridges is deemed high-cost and labour-intensive, making it unsuitable for network-wide monitoring, especially for short- and medium-span bridges. Consequently, indirect bridge health monitoring has gained widespread attention as a means of formulating rational maintenance strategies for existing bridges.

Simultaneously, discussions and recommendations are needed on how to establish a fully automatic data collection system and manage big data for comprehensive bridge maintenance decisions. The primary objectives of the workshop are twofold: 1) to review long-term and indirect methods for bridge health monitoring, and 2) to engage in discussions regarding the challenges that must be addressed for successful implementation in practical scenarios in the future.
