Numerical studies on the entire debonding propagation process of FRP strips externally bonded to the concrete substrate
TL;DR: In this paper, the authors have numerically studied the full-range behavior of FRP strips debonding from concrete substrate by using Finite Element (FE) predictions which show good correlation with experimental results.

An investigation about debonding mechanisms in FRP-strengthened RC structural elements by using a cohesive/volumetric modeling technique
TL;DR: In this article , a cohesive/volumetric modeling technique based on a diffuse interface fracture approach is proposed to in-depth investigate the debonding mechanisms in FRP-plated RC beams and subsequently validated through experimental results.

Impacts of configurations on the strength of FRP anchors
TL;DR: Comparisons between equation based predictions and 12 experimental results indicate the advantage of the proposed equation against existing equations, and a feasible technique is proposed, i.e. the bidirectional FRP patch, to improve the efficiency of current FRP anchors.

Customized shear test for bond-slip characterization of EBR FRP-concrete system: Influence of substrate aggregate type
TL;DR: In this article, a simple and improved double shear test setup was presented to ease its application in FRP-concrete bond tests in addition to satisfying other important functional requirements, and two concrete types were produced; one containing fresh aggregate and the other consisting of steel slag aggregate substituting 30% of the maximum fresh aggregate size in the first concrete type.

Bond-slip models for FRP sheets/plates bonded to concrete
TL;DR: In this paper, a review of existing bond strength models and bond-slip models is presented, and the results of 253 pull tests on simple FRP-to-concrete bonded joints, leading to the conclusion that a more accurate model is required.

Experimental study on FRP-to-concrete bonded joints
TL;DR: In this article, the authors present an experimental study on the bond shear strength between FRP and concrete using a near-end supported (NES) single-shear pull test, which was found to be in close agreement with the predictions of Chen and Teng's [J. Struct. Eng. 127(2001) 784] bond strength model.
