摘    要:设计并制作了五组经过加固或未经加固的试件,在轴向压应力为5·6MPa的情况下,进行了水平反复加载试验。试验结果表明,RC矩形柱用外包钢或碳纤维以矩形或圆形截面形式加固后,变形性能得到明显的改善;由于轴压比不大,极限承载力提高不太明显;圆形截面的承载力加固效果好于矩形截面的;外包钢加固试件的耗能能力比碳纤维加固的稍大。

关 键 词:抗震加固  外包钢  碳纤维  抗弯强度  变形

Abstract:In order to investigate the seismic behavior of RC rectangular columns strengthening with circular or rectangular steel plate and carbon fiber sheet jackets, five strengthened and non-strengthened column specimens are designed and constructed. Specimens are tested under constant axial compression stress of 5.6MPa, and alternately repeated lateral forces. The main conclusion is that the ultimate flexural strength and deformation capacity of the RC rectangular columns, which are confined laterally by the circular steel plate and CF sheet-jacket, are quite improved.
Keywords:seismic strengthening  steel plate  carbon fiber sheet  ultimate flexural strength  deformation
