Discussion of 'Flexural Behavior of Reinforced Concrete Beams with TRC Tension Zone Cover' by Shiping Yin, Shilang Xu, and Henglin Lv

摘要

Based on four-point flexural tests conducted on textile-reinforced concrete (TRC) beams, the discussed paper presents an interesting experimental study on the influences of the layers of textile, the surface treatment of textile, and mixing short fibers into fine-grain concrete on the mechanical performance and crack pattern of the beams with a TRC tension zone cover. The authors should be complimented for providing a detailed paper, which reports valuable findings of interest. The discusser would like to thank the authors for this and to also offer some comments and questions for their consideration and response, mainly about aspects related with the experimental results and discussion, such as the crack form of specimens and the load-maximum crack width curves.
