Abstract:
Since its inception in 1995, the ISIS Canada research network has developed design procedures and innovative techniques for the rehabilitation and repair of existing concrete structures using fiber reinforced polymer (FRP) materials. In co-operation with various industrial partners, ISIS Canada has conducted many field application projects, successfully transferring ISIS technology into practice in the field. This paper provides a review of four recent field applications in Western Canada, utilizing externally bonded FRP for the repair and strengthening of bridges. The projects include flexural strengthening of a bridge deck under lateral bending, shear strengthening of I-shaped AASHTO girders for two bridges, and the repair and strengthening of concrete corbels supporting a single girder pedestrian bridge. Some construction costs and the time required to complete each project are presented, as well as practical details specific to each application.
