A deep dive into recent fiber-reinforced polymer (FRP) full-scale testing under cyclic loading. FRP systems are high-strength and lightweight reinforcements created by combining fibers with a polymer material. The fibers (carbon or E-glass) provide the main reinforcing elements while the polymer matrix (epoxy resins) acts as a binder, protects the fibers, and transfers loads to and between the fibers. FRP has been traditionally used in the civil, aerospace, and automotive industries for applications requiring high strength-to-weight ratios and rigidity.
FRP strengthening has become increasingly popular in seismic retrofit projects. The industry is moving towards a thorough understanding of adequate seismic detailing of FRP systems. Simpson Strong-Tie has invested a considerable amount of lab time in the CSS V-Wrap FRP system. In the current industry state, FRP applications are designed but rarely detailed for performance and resilience. This presentation opens the black box of FRP design.
