Reference number : GC-2017-Q4-01586, amendment number : , agreement type : G, recipient legal name : Sadhu, Ayan (Lakehead University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Deterioration of aging infrastructure including highway bridges and offshore structures has significant societal_x000D_
and human consequences. Progressive damages commonly occur in bridges due to unexpected heavy traffic,_x000D_
deferred maintenance or extreme climatic events. Therefore, there is a need to assess the existing health of_x000D_
aging bridges and ensure their safe and reliable operation. My industrial partner, the engineering division of_x000D_
WSP, is strongly reliant on periodic visual inspection-based maintenance methods that are easier but_x000D_
error-prone and expensive. Ensuring their smooth operation requires newer condition-based maintenance and_x000D_
real-time monitoring, so that any damage can be detected in a timely and most cost-effective manner. The main_x000D_
objective of this proposal is to develop and share with our partner, efficient condition-based maintenance_x000D_
techniques for the bridges in the City of Thunder Bay. The challenge lies in assessing the local and global_x000D_
damage of these bridges through the unusual symptoms detected by the vibration sensors, and then conducting_x000D_
appropriate rehabilitation and retrofitting. This research will develop an automated and remote damage_x000D_
diagnosis and decision making tool that can be readily used to monitor bridges under extreme weather_x000D_
conditions. As opposed to WSP's current practice of using manual preventive maintenance, the proposed_x000D_
sensor-based technology will enable our industrial partner to automate the process of detecting catastrophic_x000D_
failures, and therefore minimize overall maintenance costs. Once developed, the proposed tool can be used by_x000D_
our partner or other Canadian infrastructure owners including the Ministry of Transportation of Canada to_x000D_
retrofit critical bridges in other metro cities under adverse weather conditions, thereby making structural_x000D_
rehabilitation more time- and cost-effective. Such autonomous and remote retrofitting technology will work to_x000D_
reduce the costs of overall maintenance on Canadian infrastructure for both the provincial and federal_x000D_
governments., program purpose french : Deterioration of aging infrastructure including highway bridges and offshore structures has significant societal_x000D_
