摘　　要：为了对18根钢筋混凝土短柱进行抗压加固试验研究,采用碳纤维和玻璃纤维两种材料分别对钢筋混凝土柱进行抗压加固,采用分级单调加载方式对所有柱进行轴心受压试验,在加载过程中,量测了试验柱的应变、变形和极限承载力。结果表明,采用纤维对钢筋混凝土柱进行加固后,其抗压强度提高,延性加大。This paper presents testing results of 18 rein- forced concrete （RC） columns compressive strengthened. Two kinds of materials were used for the strengthening. One was carbon fiber reinforced plastic （CFRP）,the oth- er was glass fiber reinforced plastic （GFRP）. Classifica- tion monotone loading acted on the center of every col- umn. In the test,both strain and deformation were meas- ured. Ultimate compressive strength was also carried out. The results show that RC columns strengthened by CFRP or GFRP can increase obviously the compressive beating capacity and ductility of the columns.
