  • 摘要: 该文对6 个圆钢管混凝土短斜柱、10 个矩形钢管混凝土短斜柱进行了竖向荷载作用下的试验研究,探讨了倾斜角度对圆、矩形钢管混凝土短斜柱抗压力学性能的影响,建议了圆、矩形钢管混凝土短斜柱强度承载力计算式。结果表明:1) 随着倾斜角度的增加,圆、矩形钢管混凝土短斜柱极限承载力和刚度均有下降的趋势;2) 建议的极限承载力计算式计算结果与试验结果总体上较为吻合,可用来预测圆、矩形钢管混凝土短斜柱的截面强度。
    Abstract: Tests on six inclined concrete-filled steel tubular stub columns with circular sections and ten inclined concrete-filled steel tubular stub columns with rectangular sections subjected to longitudinal loading were carried out to study the influence of different angle of inclination on the compressive mechanical properties, and a simplified formula is suggested for calculating the member capacity. The test results show that the compressive strength and the stiffness both decrease with the increase of the angle of inclination. Generally, the formula can reasonably evaluate the ultimate bearing capacity of inclined concrete-filled steel tubular stub columns, and the calculated results show good agreements with the experimental results.
