摘要
本文通过试验研究,用玻璃纤维布和碳纤维布分别加固完好钢梁,实测粘结不同纤维复合材料情况下钢梁的荷载-位移曲线和承载力,以评估粘贴CFRP、GFRP是否能有效地改善钢梁的受力性能和对比分析这2种材料的加固效果,为加固工程设计提供有效的参数。
Experiment is made on the complete steel girders reinforced with GFRP and CFRP separately. The load-displacement curve and carrying capacity of the steel girder are obtained. The contrastive analysis of the reinforcement effect of these two materials is conducted in order to evaluate whether the gluing of GFRP and CFRP can improve the steel girder performance so as to provide effective parameters for the strengthening design.
