In this study, we examined the effect of increasing the diameter of the CFRP strand on the structural performance of the end fixing structure with the aim of further expanding the application of the end fixing structure in the CFRP strand (6φ). For verification, the end fixing structure of CFRP strand (9φ) was formed, and a pull-out test and cross-sectional observation by X-ray CT were performed. As a result, 9φ and 6φ showed the same structural performance by increasing the shortest distance from the through hole of the CFRP socket to the outermost end of the socket.
