Deconstruction of the original Champlain Bridge

Study of the Compressive Strength of Steel Truss Bridges Made of Assembled Parts

• Research Center: National Research Council Canada (NRC)
• Researcher: Nafiseh Ebrahimi Eng., Ph.D.

This project aims to carry out a complete investigation of the painting system used on the Champlain Bridge to assess its performance in corrosion prevention under different climatic conditions. This study would provide recommendations to increase the service life of the paint and prevent its premature failure

Objectives

• Identify the failure mechanism of the current coating system
• Study the effects of the coatings age in terms of quality of original application and long-term deterioration
• Investigate the correlation of the bridge exposure environment to the damage profile of painting
• Provide a guide of best maintenance practices applicable for other steel bridges
