USE OF DOWNSTREAM-FACING AEROFOIL-SHAPED BRIDGE PIERS TO REDUCE LOCAL SCOUR

The present paper investigates the experimental study of strengthening reinforced concrete short corbel by bonding composite carbon fiber fabrics, including the local and global strain distribution, load-carrying and mode of failure. Th e influence of some parameters on mechanical behavior of strengthened structure is examined, as such as, carbon fiber fabric effect with different number of layer, type of strengthening effect by gluing directly carbon fiber fabrics on concrete corbel or by wrapping. The ultimate strength and displacement of the specimen are compared to the reference structure under monotonically increasing static bending load. The cracking and failure mode are presented.
