钢纤维高强混凝土对于改善梁结构的初始斜裂荷载作用，并不明显；

The steel fiber cannot obviously improve the loads corresponding to the first inclined cracks.

测定了在不同纤维掺量下混凝土梁的初裂冲击次数、破坏冲击次数以及冲击能。

The initial-crack, fracture impact cycle number and impact energy of these concrete beams with different fiber dosages are also tested.

结果表明，钢纤维增强钢丝网混凝土T形梁具有较高的正截面抗弯强度和良好的抗裂性能。

The results show that steel fiber reinforced ferroconcrete t beam possesses high bending strength and excellent crack resistance property.
