Nevertheless, compared with conventional (unstrengthened) RC beams, research around the size impact of RC beams strengthened in shear with EB-FRP are very handful of [3,107]. Mainly because of this gap, the influence of the size impact may not be captured by codes and Pramipexole dihydrochloride Dopamine Receptor design guidelines. This could mean that the style models for shear-strengthened RC beams may possibly fail to capture the shear strength loss when the beam size is increased. Therefore, shear-strengthening prediction based on present models could lead to an overestimation from the shear resistance and hence a non-conservative design and style. Additionally, the code and design guidelines for strengthened RC beams with EB-FRP happen to be in existence for about two decades, and their updates have failed to capture the size impact phenomenon in their most up-to-date versions. The gap revealed by various experimental investigations continues to be not accounted for within the prediction models. In reality, this can be the case for many main parameters, including: (1) the interaction amongst internal transverse steel and external FRP, which reduces the functionality of EB-FRP as reported by [18]; (two) shear strength lower with increasing beam height, as reported by [11]; and (3) modification from the web cracking pattern by a shear-strengthening program that modifies the anchorage situations of EB-FRP, as reported by [19]. These gaps are still a subject of discussion and suggestions in the literature. Consequently, consideration on the influence of those phenomena within the prediction models employed by codes and design and style guidelines is essential. The present study aims to examine the size impact in RC beams strengthened in shear with EB-FRP and to assess the accuracy in the design and style models of some top codes and style guidelines too because the influence of size impact to the contribution to shear resistance attributed to EB-FRP of these models. To this end, a database of experimental findings around the size effect in EB-FRP-strengthened beams was built based on the reported literature also as chosen partial benefits from the two original studies already published by the authors [3,11]. The information had been analysed and compared with the models of six current codes and design and style guidelines to assess their accuracy in predicting the FRP contribution to shear resistance. The database encompassed a total of 50 specimens, shear-strengthened with EB-FRP, having a beam height ranging from 180 to 750 mm, amongst which 16 T-beam specimens strengthened with EB-FRP fabric sheets and an L-shaped laminate were tested by the authors. The six codes and design and style guidelines used in this study for the design of shear-strengthened RC beams with EB-FRP had been: ACI-440.2R-17 2017 [20]; CSA-S619 2019 [21]; CSA-S806-12 2012 [22]; fib-TG5.1-19 2019 [23]; fib-TG9.3-01 2001 [24]; JSCE 2001 [25]. two. Investigation Florfenicol amine site Significance Most studies carried out around the size impact of RC beams shear-strengthened with EBFRP have been focussed on the addition of FRP as the most important study parameter. Prediction models in the contribution of FRP to shear resistance in EB-FRP-strengthened beams haven’t been updated to capture the key parameters that have been established and properly.
