Anchoring Issues of CFRP Laminates to Concrete Members

“…The theory of built-up bars was used to describe the length of the anchor. The built-up bars theory has proven to be suitable for this kind of evaluation and extended output, and application examples can be found in the following publications [16][17][18]21,23,[37][38][39]. The analytical built-up bars solution of the bond shear force depends on the load conditions of the element.…”

“…In addition, the methodology for calculating the anchor length and the pulling force is also presented. The proposed numerical technique is based on the theory of built-up bars, which proved to be appropriate for the evaluation of partial shear connection of the retrofitted members [16][17][18][19][20][21][22][23][24]. The four different types of pull-off/out shear tests are used for a comparison of experimental and numerical results: single lap shear, bending shear, double lap shear, and push-pull shear tests [25][26][27][28][29][30][31][32].…”
