摘要
通过将GFRP筋植入砂浆试块中进行拉拔试验,以研究GFRP筋直径、锚固长度和砂浆强度对GFRP筋与砂浆之间粘结性能的影响。试验结果表明,平均粘结强度随锚固长度或砂浆强度的增大而增大,但随GFRP筋直径的增大而减小。另外,粘结滑移曲线剪切刚度随砂浆强度或GFRP筋直径的增大而增大,随锚固长度的增大而减小。
Based on the pullout bond tests for the GFRP bars embedded in cement mortar, the influence of the GFRP diameter, the cement mortar strength and the bond length on the bond properties of GFRP bars to cement mortar is studied. The experimental results illustrate that the average bond strength increases with the increase in bond length or the cement mortar strength, while it decreases with the increase in diameter of GFRP bar. In addition, the shear rigidity increases with the increase in diameter of GFRP bar or the cement mortar strength, while it decreases with the bond length.
