Compared to the marked steel fiber with lower strength, the hooked steel fiber with higher strength has better effects on the flexural toughness and fracture energy of HPC. 與低強凸痕型鋼纖維相比，端部帶彎鉤的高強鋼纖維對高性能混凝土彎曲韌性和斷裂能的提高效果更為顯著(zhù)。
The mechanical and failure characteristics of SFHPC beams in bending test can be described well by using fracture energy and flexural toughness indices together. 綜合利用斷裂能和彎曲韌性指標，才能更全面地描述混凝土在彎曲過(guò)程中的受力與破壞特征。
