Abstract:
Fiber-reinforced polymer (FRP) products have become attractive materials for structural engineers in the concrete construction field, especially for strengthening existing reinforced concrete structural elements. Unfortunately, there are several drawbacks associated with using commercially available FRP systems for flexural and/or shear strengthening of reinforced concrete beams. The objective of this article is to introduce two hybrid, pseudo-ductile FRP strengthening systems designed to potentially avoid many of these drawbacks.
