Abstract. Based on dynamic triaxial experimental results for basalt fibre-reinforced coral aggregate concrete (BFRCAC), the dynamic Mohr–Coulomb (M − C), Hoek–Brown (H–B), and Drucker–Prager (D–P) strength criteria for BFRCAC are established. The results show that the dynamic strength of BFRCAC increases with an …
