EXPERIMENTAL STUDY OF THE INFLUENCE OF BFRP CLOTH U HOOP ON FLEXURAL PROPERTIES OF XINJIANG POPLAR BEAMS

Selecting 8 Xinjiang poplar beams reinforced basalt fiber cloth ( BFRP) U-type hoop and study flexural properties according to the changes of the U-shaped hoop number and location of the comparative， analyze the damage phenomena，neutral axis position changes， the bearing capacity，deflection and other performance indicators． The results showed that the BFRP sheet on the beam bottom peeled off when U hoop was not pasted on the beam，pasting U-hoop had a certain anchor role， the changes in number and location of the U-shaped hoop had different effect on the beam flexural bearing capacity and deflection，and consistent move of the neutral axis position had a tendency to move towards the compression zone．
