Champlain Bridge deconstruction | R&D project – Assessment of Corrosion and Evaluation of the Degree and Distribution of Corrosion on the Response of Girders

This month’s featured project by McGill University is progressing very well. 

 

This research project will provide information on the performance of the girders and some of the repair techniques used on the Champlain Bridge. The project is aimed to study the initiation of the corrosion in the cables and the sensitivity of the girders performance to the degree of corrosion.

 

This study will also provide valuable information on the severity of horizontal cracking in the girders webs and the determination of the condition of the prestressing cables. In addition, tests will be carried out on the secure girder which led to the installation of the “super beam” in 2013.


Three pre-stressed girders studied

 

Professor Dr. Denis Mitchell, Eng., PhD, from the Department of Engineering at McGill University, has begun his observations to assess the degree of corrosion and its distribution on the behaviour of different types of girders.

 

“Core samples are being taken from the three sections of the first girder provided by the contractor, Nouvel Horizon Saint-Laurent,” said Moctar Sidibé, Senior Engineer in the Expert Assessment, Research and Applications Directorate at The Jacques Cartier and Champlain Bridges Incorporated.
