Existing approaches for the size effect seem transferable as well. The study shows that these FRP calculation models also predict the ultimate shear force for textile-reinforced concrete (TRC) tests presented in this paper with sufficient accuracy. The experimental shear strengths were compared to predictions from existing models for shear of fiber-reinforced polymer (FRP)-reinforced concrete.

Interestingly, direct load transfer was activated up to a shear slenderness ratio of 4, which is significantly higher than in reinforced concrete ( a/ d < 2.5–3) and may result from the bond characteristics of the textile reinforcement.

Increasing the structural depth of members led to a reduction in relative shear strength, while variation of shear slenderness controlled the efficiency of direct stress fields between load introduction and support. The shear-span to depth ratio and member size were key variation parameters in this study. In this paper, the results of an experimental campaign on 27 carbon-textile reinforced slab segments tested in three-point bending are presented. Especially for thin slabs, systematic experimental investigations are lacking. Unlike designs for bending, the development of models for shear is still the subject of current research. A reliable and economic utilization of textile-reinforced concrete in construction requires appropriate design concepts.
