摘要：为了研究大断裂应变纤维布（LRS-FRP布）、芳纶纤维布（AFRP布）和碳纤维布（CFRP布）加固钢筋混凝土短柱的轴压性能，共设计了9根钢筋混凝土短柱试件，研究了FRP布种类以及粘贴方式、层数、角度对轴压性能的影响，对比分析了加固后试件的破坏特征、极限承载力和延性，并利用ABAQUS软件进行了有限元分析。结果表明：CFRP布对极限承载力的提高效果最显著，但试件加固后仍表现出明显的脆性破坏；LRS-FRP布和AFRP布对极限承载力的提高效果与CFRP布相差不大，但二者对延性改善明显，且LRS-FRP布的约束效果更优；FRP布粘贴方式和角度对轴压性能的影响小，在满足承载力的前提下，以90°间隔粘贴FRP布更加合理；有限元模拟结果与试验结果吻合较好。

Abstract: In order to study the axial compression performance of reinforced concrete short columns strengthened with large rupture strain fiber reinforced polymer(LRS-FRP), aramid fiber reinforced polymer(AFRP) and carbon fiber reinforced polymer(CFRP) sheets, nine reinforced concrete short columns were designed, and the effects of FRP sheet type, bonding type, number of layers and angle on the axial compressive performance were studied. The failure mode, ultimate bearing capacity and ductility of strengthened columns were compared and analyzed. The finite element analysis was carried out by using ABAQUS software. The results show that the ultimate bearing capacity of CFRP sheets strengthened column is significantly improved, but the column still shows brittle behavior after strengthening. The improvement on ultimate bearing capacity of LRS-FRP and AFRP sheets is similar to that of CFRP sheets, and LRS-FRP and AFRP sheets can improve the ductility obviously and the restraint effect of the former is better. Bonding type and angle have little influence on axial compression performance, and under the premise of meeting the bearing capacity, it is more reasonable to bonding FRP sheets at 90° intervals. The finite element simulation results are in good agreement with the experimental results.
