摘要

摘要: 该文采用GFRP管对轴心受压角钢构件进行抗屈曲加固,对3种长细比、2种加固构造形式的9个试件进行轴压试验,试验研究表明：该抗屈曲加固方法具有较好的施工可操作性,GFRP管抗屈曲加固方法提高了受压角钢构件的抗屈曲能力。加固后角钢构件的极限承载力提高了6.16% ~ 37.58%,延性得到一定程度的提高；该方法对长细比较大的构件加固效果较明显,且破坏模式发生一定变化。该文提出的GFRP管刚度贡献系数的计算公式,修正后计算结果与试验值吻合较好。

Abstract: This paper uses a glass fiber reinforced polymer (GFRP) tube to strengthen an axial compressing angle steel component to avoid buckling. The axial compression experiments of nine specimens have been carried out for investigating the factors of three slenderness ratio and two kinds of reinforced structure forms. The experimental study show that the anti-buckling strengthening method has good operability. The GFRP tube buckling strengthening method improves the buckling capacity for compression angle steel members. The ductility of strengthened angle steel components is improved and the ultimate bearing capacity increases by 6.16% ~ 37.58%; the method of slenderness larger component reinforcement effect is obvious, and the failure mode must be changed. The results calculated by revised formulas for GFRP tube stiffness contribution coefficients proposed are in a good agreement with the test results.
