000022426 520__ $$2eng$$aThe successful validation of a numerical model is presented that can realistically approximate the shear behavior of reinforced concrete (RC) T-section beams strengthened against shear with externally applied open hoop steel fiber reinforcing polymer (SFRP) strips. For this purpose, the measured load-deformation response of three (3) full-scale R/C beam specimens is utilized. These specimens were imposed in a cyclic loading sequence up to failure. Open hoop steel FRP strip shear reinforcement was applied externally to upgrade the shear capacity of two (2) RC beam specimens. For the first specimen the SFRP strips were applied without anchorage, whereas for the other strengthened specimen the SFRP strips were attached together with a novel anchoring device. The successful numerical simulation predicts with a very good degree of approximation the observed load-deformation behavior and the ultimate shear capacity of all these specimens as well as the observed modes of failure including diagonal concrete cracking, debonding of the CFRP strips in the case of no anchoring, or the plastification of parts of the anchoring devices plus the adjacent crushing of the concrete.
