【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。更多还原

【Abstract】 This paper presents testing results of 18 reinforced concrete(RC) columns compressive strengthened.Two kinds of materials were used for the strengthening.One was carbon fiber reinforced plastic(CFRP),the other was glass fiber reinforced plastic(GFRP).Classification monotone loading acted on the center of every column.In the test,both strain and deformation were measured.Ultimate compressive strength was also carried out.The results show that RC columns strengthened by CFRP or GFRP can increase obviously the compressive bearing capacity and ductility of the columns.更多还原
