14 bearings being studied by ÉTS 

In January, Dr. Lotfi Guizani, PhD, Eng., from the Department of Construction Engineering at the École de technologie supérieure (ÉTS), received 14 bearings from the original Champlain Bridge to carry out his project on the Improvement of Hysteretic Behaviour of Fretted Elastomeric Bearings for Seismic Isolation of Bridges. 

“Right now, this research team is visually examining all bearings recovered from the bridge and taking samples for characterization tests. They are also performing a literature review on the mechanical properties of natural rubber-based elastomers and the effect of aging,” said Moctar Sidibé, Senior Engineer from the Expertise, Research and Applications Directorate at The Jacques Cartier and Champlain Bridges Incorporated.
