Anchoring externally bonded FRP sheets is becoming a necessity to enhance the behavior of strengthened concrete beams. However, before realizing the benefits of strengthening in practice, reliable design methods need to be established to safely and efficiently account for such structural improvement. In this study, the design models for the installment of FRP splay anchors are reviewed. These models are used to evaluate the response of beams anchored in flexure and independently tested in the literature to comparatively examine the effectiveness of such anchorage models. A newly developed set of design equations is calibrated against some test data then assessed using other experimental results. The importance defining the design parameters that control this phenomenon is realized. Accordingly, the authors make an effort to define the testing matrix for each one of the key parameters identified so that future research studies consistently examine these parameters. This will ultimately enrich the current database of experimental data points used to qualify targeted results that helps establish more robust design procedures. This study is expected to directly feed into the work of ACI 440.2 task group on FRP anchorage design.
