Development of a pretensioning anchorage for sand-coated cfrp tendons: modeling and validation

HIGHLIGHTS

• who: Gian-Luca Zu00fcst et al. from the differential angle can reduce the stress concentration on the CFRP tendonThis concept is well known today as it was introduced in FRP tendon anchorages first by Prof. Shrive of Queens University in Canada , years ago [15]. This paper presents a finite element model for assessing a wedge anchor to prestress a sand-coated d=7., mm CFRP tendon and the validation of the internal strain profile with a distributed fiber optical sensor. The developed FE analysis reproduces the continuously measured strain with good accuracy and is capable to predict . . .
