## 4 Conclusions  
In this paper, the flexural performance of the flexural members of steel-textile-reinforced concrete and appropriate textile reinforcement methods were verified. Toward this end, the reinforced concrete (RC) specimens and the six steel-textile-reinforced concrete (TRC) specimens were compared.  
1. The textile was placed over the steel reinforcement, which had a remarkable reinforcement effect on the flexural behavior of the TRC specimens, resulting in the same type of flexural cracking in all specimens. It was found that TRC was more advantageous for distributing cracking evenly because cracking occurred more frequently overall in TRC than in RC.
2. The flexural performance of the specimen increased with increasing the textile reinforcement amount. However, the results of comparing the T1-T1.5 and T1.5 -T2_1 textile results showed that the performance of the test did not increase proportionally with the increase of the textile reinforcement amount. This was because as the textile reinforcement amount increased, slippage occurred because the bond of concrete to inner textile reinforcement was not perfect.
3. When the mesh of the textile was made smaller, the number of contacts in the warp and weft rovings of the textile increased, which prevented slippage between the textiles. In addition, when reinforcing the same textile reinforcement amount, the area of fiber that was unbonded from concrete was reduced, thereby securing a flexural performance close to the design value.

4. The adoption of the textile reinforcement hook for textiles significantly improved the flexural performance and was proven to be effective at controlling the deflection of the beams despite the low rigidity of the used textile.
5. In most of the TRC specimens in this study, ductility similar to that of the RC specimen was found; therefore TRC can be expected to have a sufficient ductility for beam stability. The load comparison at the same maximum allowable deflection for the TRC usability verification proved that TRC was disadvantageous compared to RC. Regarding the textile reinforcement hook, the TRC specimens showed better performance than the RC specimen. The experiment in this study, however, considered the flexural performance of the flexural members of steel-textile-reinforced concrete in special cases; therefore further research is needed to generalize the experimental results.
