摘要
通过对9根混凝土圆柱的轴心受压试验,研究了碳纤维布加固混凝土柱后的破坏特征和受力性能。试验结果表明,用碳纤维布加固可以获得优良的力学性能,可使加固试件的极限荷载大幅度提高、混凝土的变形能力大大提高,混凝土柱的延性得到显著改善。
Through axial compression test of nine concrete columns, this paper studies the destruction characteristics and force performance of concrete column after being strengthened by carbon fiber clothes, and shows that carbon fiber clothes reinforcement can gain well mechanical property, increase ultimate load of test piece, elevate deformability of concrete, and obviously ameliorate the ductile of concrete column.
