Capacité de charge des caillebotis en PRFV dans les ponts et passerelles de navires
FRP grating has gained widespread acceptance in the marine industry due to its exceptional corrosion resistance, lightweight nature, and durability. This paper focuses on the load-bearing capabilities of FRP grating in vessel decks and walkways, providing a comprehensive overview of its performance characteristics and design considerations. Material Properties of FRP Grating FRP grating is composed of fiberglass fibers embedded in a resin matrix, typically polyester or vinylester. The combination of these materials results in a composite material with the following properties: – High Strength-to-Weight Ratio: FRP grating offers excellent strength while maintaining a lightweight structure.– Corrosion Resistance: It is highly resistant to corrosion from saltwater and chemicals commonly found in marine environments.– Non-Conductive: FRP grating does not conduct electricity, making it safe for use in electrical applications. Design Considerations for Load-Bearing Applications When designing FRP grating for vessel decks and walkways, several factors need to be considered: 1. Load Requirements: The anticipated loads must be determined based on the intended use, such as pedestrian traffic, equipment weight, or vehicle loads.2. Support Structure: The underlying support structure must be designed to accommodate the loads and ensure the stability of the grating system.3. Deflection Criteria: Deflection limits are established to ensure that
