【摘要】 通过对4根内嵌碳纤维筋加固钢筋混凝土梁试验研究,在保证嵌入碳纤维筋锚同长度的前提下,尝试采用不同位置的嵌入方式,对不同部位嵌入对承载力提高的影响进行分析,并对嵌入式FRP筋承载力进行理论分析和承载力提高计算,提出了抗弯承载力增强计算方法,结果表明试验取得了较好的吻合效果。更多还原

【Abstract】 4 RC beams are experimented for strengthening with NSM concrete CFRP bars.And the enoagh anchorage length is guaranteed,while mounting in the different place of beams like the side and the bottom of beams.The influence of capacity improving is studied according to the vary position.As a result beam side mounting is a reasonable style replacing bottom mounting.On the foundation of tests and theoretical analysis the method of shear and fiexural computing are put forward to estimate the improving of capacity,which results are almost accord with test.更多还原
