摘要
选用32根不同配筋量的缩尺梁,进行不同预加超载幅值的重复加载预裂,并采用碳纤维和钢板加固,主要研究了具有不同损伤的被加固梁在加固前、后的受力状态,以及粘贴加固超载预裂梁在荷载作用下原结构和加固材料之间的内力分配,对进一步认识粘贴加固结构复合截面工作机理具有很好的参考价值.
Based on the experiment of 32 concrete scale beams strengthened with CFRP and steel sheet, the mechanical characteristics of inordinately overload pre-cracked beams are analyzed before and after strengthening, especially the internal force distribution between the raw and reinforcing material of reinforced section is studied, which can lead us to a further understanding of the working mechanism of strengthened beam.
