Five same types of C-BJs with BFRP have been cast together for experimental verification named J0-J4 compared with the joints with CFRP test by our team in a previous period [18]. The same size and concrete grade as reference [15] were used in this experiment (Fig.1). The ultimate strength of BFRP was 3200MPa and the modulus was 90GPa. In addition, the compression strength of concrete wais 24MPa and the modulus was 26000MPa.
