From: Structural performance of UHPC-columns reinforced with basalt bars under cyclic loading
Hysteresis loops of UHPC column specimens reinforced with steel and basalt bars under cyclic lateral loading: (a) Specimen reinforced with 10 mm steel bars, showing the cyclic lateral load–displacement response. (b) Specimen reinforced with 12 mm steel bars, illustrating hysteretic behavior under increasing drift levels. (c) Specimen reinforced with 10 mm basalt bars, highlighting the hysteresis loop characteristics and stable energy dissipation. (d) Specimen reinforced with 12 mm basalt bars, demonstrating enhanced strength and reduced stiffness degradation. (e) Specimen reinforced with 10 mm basalt bars, showing consistent hysteretic response and effective crack control during cyclic loading. (f) Specimen reinforced with 12 mm basalt bars, presenting superior cyclic performance and larger energy dissipation capacity compared with steel-reinforced counterparts.
