| 摘 要： | 通过设计制作加载装置和位移传感器对三种不同钢纤维掺量(0、1%、2%)的预应力钢纤维混凝土板进行了弯曲试验研究,得到了弯曲过程中预应力钢纤维混凝土板跨中的荷载-挠度曲线,揭示了预应力钢纤维混凝土板的跨中挠度在弯曲加载过程中呈现三阶段变化,并且钢纤维的加入有助于提高板的弯曲韧性,通过等效截面法计算得出了不同钢纤维掺量板的抗弯强度.

| Abstract: | Bending characterastics of steel fiber reinforced prestressed concrete slab(SFRPCS) with different steel fiber volume ratio(0,1%,2%) were investigated by designing loading device and displacement transducer.The load-deflection curve at the middle of SFRPCS was obtained,which shows that the development of deflection can be divided into three-stage,and the bending toughness of slab with steel fiber is increased a lot.The bending strength of SFRPCS is calculated according to equivalent cross section method. |

| Keywords: | steel fiber reinforced prestressed concrete slab bending experiment load-deflection curve bending strength |
