Note: a, b, c, d, e, f, and g represent 0, 0.6, 0.9, 1.2, 60, 80, and 100 kg/m3 of fiber content, respectively. n, p, and s represent plain concrete, PFRC, and SFRC, respectively. represents loading rate. The displacement loading rates of 0.03045 mm/s, 1.1004 mm/s, 2.52 mm/s, 9.45 mm/s, and 21 mm/s, respectively, correspond to 1.45 × 10−4/s, 5.24 × 10−3/s, 1.2 × 10−2/s, 0.45 × 10−1/s, and 0.1/s.
