文章通过4根GFRP管高强混凝土组合柱轴压试验,研究了加载方式及混凝土强度等参数对组合柱受力性能的影响.试验结果表明,组合柱承载力随着混凝土强度增加而增加,试件全截面受压时承载力较核心混凝土单独受压时高。根据试验研究与理论分析,建立GFRP管高强混凝土组合柱轴心受压承载力计算公式,理论计算结果与试验结果吻合良好。 In this paper, four GFRP tubular high-strength concrete composite column axial compression tests were carried out to study the influence of loading method and concrete strength on the mechanical behavior of composite columns. The experimental results show that the bearing capacity of composite columns increases with the increase of concrete strength, When the whole section is under pressure, the bearing capacity is higher than when the core concrete is solely pressed. According to the experimental research and theoretical analysis, the formula for calculating the axial compressive bearing capacity of GFRP tubular high-strength concrete composite columns is established. The theoretical calculation results are in good agreement with the experimental results.
