Experimental Investigation of BFRP Tendons under Monotonic and Hysteretic Loadings

Basalt fiber reinforced polymers (BFRPs) have been widely used in structures because of their high strength and light weight advantages. The previous research neglected the effect of the bonded anchor which led to overestimated performances of the BFRP tendons. In this study, experiments on the mono...

description	Basalt fiber reinforced polymers (BFRPs) have been widely used in structures because of their high strength and light weight advantages. The previous research neglected the effect of the bonded anchor which led to overestimated performances of the BFRP tendons. In this study, experiments on the monotonic and hysteretic behaviors were conducted to analyze the mechanics of the BFRP tendons with bonded anchors.

The colloidal deformations, which accounted for about 20% of the whole deformation of the BFRP tendons, cannot be neglected in the predicted responses of the BFRP tendons. The regressed formulas of the anchor colloidal deformation could effectively anticipate the monotonic and hysteretic responses of the BFRP tendons.
