Analysis, Testing and Field Applications of GFRP Tubes for Pile Column Applications
Glass Fiber Reinforced Polymer (GFRP) tubes filled with concrete can develop very high strength in compression. The filament architecture plays an important role in the properties of the tube to provide the confinement to the concrete. Apart from providing confinement, GFRP tubes also serve as formwork and protects concrete from deterioration. Piles and columns generally act as compression members and will be subjected to bending and tensile stresses during handling and erection. However concrete is weak in tension and needed to be strengthened. Strengthening of concrete can be done by providing reinforcements inside the GFRP tube or by prestressing the concrete core. This paper deals with the design and tests conducted on GFRP tubes with 300 mm (12 in.) and 400 mm (16 in.) dia. filled with concrete for pile/column requirements for the Ohio Department of Transportation (O-DOT). As a result of this study, six — 400 mm (16 in.) diameter and 16.76 m (55ft.) long GFRP tubes filled with concrete and prestressed were used for pile/column application for a real bridge in Ohio.
