Structural Behavior of HFRP-UHPFRC Composite Girders
This paper presents the structural behavior of composite girders composed of glass/carbon fiber reinforced polymers (GFRP/CFRP) I-profiles and precast Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) slabs. Three full-scale composite girders with varying UHPFRC slab widths were tested under four point loading to examine the flexural behavior of the composite girders. Shear connectors with/without epoxy bonding were used. The bolt shear connectors and epoxy were used to resist the horizontal shear flow at the interface between the hybrid CFRP/GFRP (HFRP) I-profile and the UHPFRC slab. The composite action between the HFRP I-profile and UHPFRC slab was investigated. The test results showed that the composite girders exhibited significant improvements in stiffness and strength, above those of single HFRP girders. Three-dimensional nonlinear finite element (FE) analysis was carried out and compared against the experimental results of the tested girders. A fairly good agreement among the experimental and FE analysis results was found. The study revealed that the HFRP-UHPFRC composite girders are efficient and can provide a competitive, cost-effective and sustainable solution to bridge structures.
