摘要
对利用外包钢管加固的钢筋混凝土柱承载力进行试验研究,测定了不同加固方法对其承载力的影响。试验和理论结果表明,外包钢管加固钢筋混凝土柱能够充分利用两种组成材料的受力性能,在截面面积增大不多的情况下大幅提高柱的承载能力。并提出其轴心受压和偏心受压的承载力经验公式。研究成果可为工程应用提供参考。
The influence of different methods on the bearing capacity of RC columns strengthened with steel tubular shell is investigated. The experimental and theoretical results show that the RC columns strengthened with steel tubular shell take full advantage of loading properties of both materials, thus greatly improve the member＇s bearing capacity without enlarging the areas of cross-section much, and the experienced strength formulas under axial and eccentric compression are presented. The results can be refered to for engineering application.
