Production Testing of CFRP Grid Reinforced Concrete Panels for a Floating Pier

Discussed are construction and cost considerations for a proposed pier concept that offers a design alternative to the traditional pile supported structure. The goal of the design is that the pier has maintenance free service life of 100 years and is flexible in function and location. The hull concept for the proposed floating pier consisted of posttensioned lightweight concrete panels reinforced with carbon fiber reinforced polymer (CFRP) grids for crack control and toughness. The concept of CFRP grid reinforcement has been deferred because of the high cost of CFRP and the unknowns related to the durability of CFRP reinforcement exposed to marine environment.
