First Smart Prestressed Concrete Highway Bridge in Canada

چکیده
Deterioration of concrete members due to corrosion of steel reinforcements is one of the major problems which reduces the service life time of bridges, especially in Canada due to the use of de·icier applications. The cost of correcting corrosion-induced distress in bridges is high compared to the capital cost of the structure. To overcome this problem, the City of Calgary has decided to construct the first concrete highway bridge in Canada using advanced carbon fibre composite cables, CFCC, produced by Tokyo Rope, Japan and Leadline rods produced by Mitubishi Kasei, Japan. In addition to their corrosion-resistant characteristics, these material have outstanding characteristics in terms of a high strength to weight ratio, a non-magnetic quality. a high resistance to impact. and an ease of handling and installation due to their light weights.

First Smart Bridge in Canada
On November 5, 1993, the City of Calgary completed the construction of the first smart prestressed concrete highway bridge built in Canada. A total of six pretensioned girders of a continuous two span skew highway bridge were prestressed using carbon fibre composite cables (CrCC) developed by Tokyo Rope, and Leadline rods produced by Mitsubishi Kasei, Japan. This paper describes the constructio...

Since the 1950’s, prestressed concrete beams have become a factor in almost one third of all new bridge construction in the United States. In Michigan, prestressed concrete was introduced in 1954 and the first prestressed concrete side-by-side box-beam bridge was built in 1955. Pontis data indicates 2,054 side-by-side prestressed concrete box-beam bridges in Michigan; 236 are part of the Nation...
