中文摘要：

为研究加筋高性能砂浆（HPFL）-粘钢联合加固混凝土柱的轴心抗压承载能力,进行了8根HPFL-粘钢联合加固RC柱轴压试验,结合国内已有的35根HPFL加固柱轴压试验结果,分析了加固柱的破坏机理和承载力影响因素,并提出此类加固柱轴压承载力计算方法。研究结果表明：此类加固柱共同工作性能良好,极限承载力提高了22%~52%;角钢倒角对钢绞线早期剪断有很大影响;粘贴角钢时加固箍筋强度折减系数取0.55,若无粘贴角钢并对构件进行适当倒角时可取0.72,倒角直径大于边长1/3时可取1.0;钢板表面砂浆的承压有效利用系数取0.7,其余部分取0.3;提出的承载力公式计算值与试验值符合较好,可用于轴压柱加固承载力计算。

英文摘要：

In order to investigate the axial compression bearing capacity of RC columns strengthened with high performance ferrocement laminate（HPFL）and bonded steel plates,axial compression tests were carried out on 8strengthened column specimens.Combined with domestic experiments of 35 columns strengthened with HPFL,failure mechanism and effect factors on bearing capacity were analyzed,and the calculation method of bearing capacity of axial compression was proposed.The results show that the strengthened columns have good working performance,and the ultimate bearing capacity increases by 22%to 52%.The influence of angle bar＇s chamfering on premature break of steel wire is significant.The value of strength reduction factor of the reinforcing stirrup is 0.55 when angle bars are used.If there is adequate chamfering of the original members and no angle bars,the value of the factor is 0.72.If the diameter of the chamfering is larger than 1/3of the side length,the value of the factor is 1.0.Pressure effective utilization coefficient of the mortar on steel plate surface is 0.7,and the rest is 0.3.The calculation values of the proposed formulae are in good agreement with the test results,so the proposed formulae can be used to calculate bearing capacity of axial compression columns.
