Abstract
Glass fibre-reinforced polymer (GFRP) reinforcement presents a promising solution to the durability issues affecting steel-reinforced concrete in marine infrastructure. This review assesses the current state of practice for GFRP-reinforced concrete decks, including non-prestressed, prestressed monolithic, and segmental systems. It identifies the key design parameters - reinforcement ratio and stiffness, deck geometry, concrete strength, pre-tensioning level, and joint details - that govern flexural capacity, shear resistance, and fatigue life. Segmental GFRP-prestressed decks emerge as an advantageous alternative to conventional monolithic construction, providing rapid installation and modular replaceability. Moreover, incorporating the FRP-reinforced segmental deck allows for modular construction in the maritime environment. However, maintaining a pre-compression of 1-2 MPa at segment joints is essential to prevent localised failures. The review discusses critical research gaps, and recommendations are provided to guide design improvements and future studies. By using the GFRP's non-corrosive nature, designers can achieve concrete decks with a service life beyond 50 years.
