对26个不同埋深、不同直径和不同砂浆强度的GFRP筋与砂浆拉拔试件进行了拉拔承载力以及粘结强度的研究。结果表明,拉拔承载力随着埋深的增加而增大,随着砂浆强度的增大而增大,但随着直径大小的变化不明显;粘结强度随着拉拔试件的埋深的增大而减小,随着直径的增大而减小,随着砂浆强度的增加而增大。利用ANSYS程序对GFRP筋与砂浆拉拔试件进行了仿真分析,结果表明,模拟结果与试验结果较为接近,即利用ANSYS软件能够较为准确用来验证试验结果。
The drawing capacity and bond strength of 26 GFRP tendons and mortar drawn specimens with different depths, different diameters and different mortar strengths were studied. The results show that the bearing capacity of bearing increases with the increase of buried depth and increases with the increase of mortar strength, but it does not change with the diameter. The bond strength decreases with the depth of the drawn specimen Decreases with the increase of diameter, and decreases with the increase of mortar strength. The ANSYS program was used to simulate the GFRP tendons and mortar drawn specimens. The results show that the simulation results are close to the experimental ones, that is, the ANSYS software can be used to verify the test results more accurately.
