Large GFRP-Confined Concrete Columns Subjected to Simulated Seismic Loads
A huge inventory of concrete structures exists in many parts of the world that have been made deficient due to steel corrosion. The columns damaged by steel corrosion in these structures are especially vulnerable to events such as an earthquake. In this research, the use of GFRP bars in full-scale columns has been investigated as an alternative to steel reinforcement for sustainable construction. As columns containing GFRP longitudinal and lateral reinforcements display softer responses with lower shear and flexural capacity, the behaviour of columns with lateral GFRP reinforcement but steel longitudinal bars was investigated. The experimental program involved testing of eight full-scale, 508 mm diameter, concrete columns under simulated seismic loading. Variables included level of axial load, amount of confining reinforcement and spacing of transverse reinforcement. The columns performed in an excellent manner and the GFRP spirals were found to provide increasing confining pressure to the large concrete core with increased deformations until either their rupture or crushing of the concrete. Results from selected specimens from this and earlier test programs are presented to highlight the effects of different variables and establish the feasibility of using GFRP spirals for seismic resistance of columns.
