FRP FLEXURAL AND SHEAR REINFORCEMENTS FOR HIGHWAY BRIDGES IN MANITOBA, CANADA A.Z. FAM, A.A. ABDELRAHMAN and S.H. RIZKALLA Civil and Geological Engineering Department, University of Manitoba, Winnipeg, Manitoba, Canada W. SALTZBERG Highway and Transportation, Bridges and Structures Department, Manitoba, Canada Abstract The province of Manitoba accepted the Challenge to construct the world largest span concrete highway bridge prestressed and reinforced for shear using carbon tibre reinforced plastic (CFRP) reinforcement. Portion of the concrete deck slab is also reinforced exclusively by FRP reinforcements. This paper describes the experimental program conducted at the University of Manitoba, Canada to examine the behaviour of 1:3.6 scaled model of the bridge girders. The paper discusses the construction details of the test beams which are identical to those planned for the bridge girders. Preliminary test results including flexural behaviour, shear behaviour and modes of failure are presemed. Keywords: Beam, bridge, carbon, FRP, model, shear, prestressed concrete. 1 Introduction Bridges in Canada are exposed to harsh environments characterized by a wide range of temperature variation and use of salt for de-icing in addition to the typical effects of cyclic and impact loads of traffic. The cost of correcting corrosion-induced distress in bridges is high compared to the capital cost of the structure. To overcome this problem the province of Manitoba is undenaking the challenge to construct the largest span highway concrete bridge with 32.5 meter span using two types of CFRP reinforcements for prestressing and stirrups. The two types of CFRP are Carbon tibre Composite Cable, CFCC, produced by Tokyo Rope, Japan and Leadline produced by Mitsubishi Kasei, Japan. In addition to their corrosion-resistant characteristics, the two types of materials have outstanding characteristics in terms of high strength-to- - lOS - I: , I I I
