GNSS and Earth Observation for structural health monitoring of long-span bridges - GeoSHM A case study of the Forth Road Bridge
Implementation of structural health monitoring(SHM)systems on long-span bridges has become mandatory in many countries to ascertain the safety of these structures and the public,taking into account an increase in usage and threats due to extreme loading conditions.However,the successful delivery of such a system has faced many challenges including non-optimal in-situ sensor placement and the failure to extract damage and reliability information from monitoring data to assist bridge operators with their maintenance planning and activities.Supported by the European Space Agency(ESA)under the Integrated Applications Promotion(IAP)scheme,the project GNSS and Earth Observation for Structural Health Monitoring of Long-span Bridges or GeoSHM aims to address some of these shortcomings.The primary objectives of the project are to develop a complete SHM framework including an integrated GeoSHM sensor system and an innovative GeoSHM data strategy to evaluate the health status of longspan bridges.Following the success of the Feasibility Study,the GeoSHM Demonstration Project was initiated in March 2016 and is expected to finish in December 2018.Some key aspects of the GeoSHM Demonstration Project will be discussed in this paper with a focus on the development of the GeoSHM system on the Forth Road Bridge in Scotland,which is one of the three test structures in this project.
