Mechanical Properties of RC Stub Columns with Corroded Stirrups Strengthened by Grouted GFRP Jackets Reinforced with CFRP Grids Under Axial Compression

  • 摘要: 通过13根碳纤维增强复合材料(CFRP)网格增强玻璃纤维增强复材(GFRP)套筒加固箍筋锈蚀钢筋混凝土(RC)短柱轴压试验,研究了CFRP网格层数和箍筋锈蚀率对箍筋锈蚀钢筋混凝土短柱荷载-轴向位移曲线、极限承载力、破坏形态的影响规律。研究结果表明:加固柱破坏时整体表现为脆性破坏;GFRP套筒加固使箍筋锈蚀RC柱极限承载力最高提升59.4%,CFRP网格作为增强材料使加固柱极限承载力最大提升87%;CFRP网格层数相比箍筋锈蚀率对加固柱的荷载-轴向位移曲线产生的影响更大,且层数越多,曲线在弹塑性阶段的强化程度越明显;采用CFRP网格包裹的加固试件极限承载力随网格层数的增加而递增,极限承载力随箍筋锈蚀率的增大,增长幅度呈现下降趋势。研究结果可以为实际箍筋锈蚀桥墩加固提供试验依据。
