Abstract

Abstract

Through the pull-out test of Glass Fiber Reinforced Polymer(GFRP) bent bars reinforced Ultra High Performance Concrete(UHPC), the mechanical performance and damage mechanism of GFRP bars in bending zone were studied. The cooperative performance of GFRP bent bars and UHPC was revealed. The stress model of specimens was established. The study variables include: diameter of GFRP bars, anchoring length of the tail end of bent bars, shapes of the tail ends of bars and types of bar matrix. The results showed that the diameter of GFRP bars had a great influence on the bending strength due to the influence of the fold in the bending area and the stress concentration on the shoulder. The increase of the anchoring length at the tail of the GFRP bars had an positive effect on the bending strength of GFPR bars within a certain range, while the shape of tail end (L-shaped and U-shaped) bars had a little influence on the bending strength. The failure mechanism of GFRP bars under tension in the bending zone was presented, and three stages of fracture process of GFRP bars were revealed: the matrix cracking at the inside of stressed shoulders of bars, the inner fiber cracking and the outer fiber cracking. A stress analysis model was established for the bending area of GFRP-UHPC in the pull-out state.
