Biography Summary

Scott Walbridge is a Civil and Environmental Engineering Associate Professor at the University of Waterloo and a registered Professional Engineer in Alberta. He is an active member of Canadian Standards Association (CSA), American Society for Civil Engineering (ASCE) Structural Engineering Institute (SEI) and a corresponding member of European Convention for Constructional Steelwork (ECCS).

Professor Walbridge also supervises the “Metal structure assessment and repair” research group at UWaterloo. The group’s primary mission is to develop new methods and technologies for the assessment and repair of damaged or deteriorating metal structures; and to develop new solutions for employing metals for the temporary or rapid replacement of other damaged or deteriorating civil or industrial infrastructure. In addition, they aim to investigate the influence of decisions made at the design stage on the durability and maintenance-related life-cycle costs of metal structures.

The group also develops design provisions, so that engineers can incorporate these new methods and technologies into their maintenance programs. They perform an economic analysis of these new methods and technologies to identify conditions under which their use would result in reduced life-cycle costs.

Some of the past projects of the group include fatigue testing and analysis of bridge welds retrofitted by impact treatment and analysis of aluminum bridge welds; fatigue retrofitting of welded steel cover plates using pre-stressed CFRP strips; predicting and prolonging the service lives of corroding weathering steel bridges; development of a shear connection for a portable composite bridge, and aluminum highway bridges: design and life-cycle cost analysis.

In addition to his research work, Professor Walbridge has over 30 refereed journal and conference publications.
