摘要
为了研究GFRP混凝土梁的抗弯性能,采用500 k N千斤顶对其进行了静抗弯性能试验。作为主要受力筋,GFRP型材与混凝土粘结性能良好,能够协同工作,共同受力;混凝土强度等级和箍筋间距对GFRP混凝土梁的极限承载力影响不明显,但箍筋间距对其破坏形态有明显影响; GFRP混凝土梁达到极限荷载时,具有较好的变形恢复能力,且变形满足规范要求。
In order to study the bending characteristics of GFRP reinforced concrete beams,static bending tests were carried out by adopting the500 k N jack. The bonding performance and the deformation coordination of the GFRP reinforced concrete are excellent. The effect of concrete strength grade and stirrup space on the ultimate bearing capacity of the GFRP reinforced concrete beams is small,but the stirrup spacing has significant effect on the damage shape. The GFRP profile bar beams have excellent deformation restoring capacity and the deformation can met the requirements of the specification.
