Bond Properties of High-strength Bars Embedded in Ultra-High-Performance Fibre-Reinforced Concrete

Description

Fig. 6 Average bond stress–slip curves for different parameters: (a) concrete type (UHPFRC and NSC); (b) fibre content by volume; (c) bar diameter; and (d) bonded length-to-bar diameter ratio. Fig. 9 Distribution curves of bond stress along the bonded length: (a) Specimen U-SF2%-3D-20-g-c; (b) Specimen U-SF2%-4D-20-g-b. Fig. 10 Distribution curves of relative slip: (a) Specimen U-SF2%-3D-20-g-c; (b) Specimen U-SF2%-4D-20-g-b. Fig. 11 Bond stress–slip curves as a function of the longitudinal coordinate: (a) Specimen U-SF2%-3D-20-g-c; (b) Specimen U-SF2%-4D-20-g-b. Fig. 12 Positional function curve: (a) Specimen U-SF2%-3D-20-g-c; (b) Specimen U-SF2%-4D-20-g-b. Fig. 13 Comparison of stress–slip stress curves between experiment and model: (a) Specimen U-SF2%-3D-20-c; (b) Specimen U-SF2%-4D-20-b.
