1g model tests of vertically loaded GFRP piles

Abstract

The conventional piling materials (i.e., concrete, steel, wood) are more likely to have durability problems (i.e., corrosion, degradation, deterioration) in harsh environments and offshore construction. Fiber-reinforced polymer (FRP) was found to be a potential alternative to the conventional materials due to its high corrosion resistance which results in higher durability and longer life span. In Geotechnical engineering, more data is required to adopt this new composite material in the piling industry. This paper presents a small-scale experimental study on Glass FRP (GFRP) pile under axial loads and the results were compared to a steel reference pile. The results showed a slightly better performance for GFRP pile under axial loads compared to steel pile due to its higher friction resistance in sand.
