摘要
通过对6根钢管再生混凝土短柱及3根普通钢管混凝土短柱进行轴压试验,研究不同长径比和再生骨料取代率对钢管再生混凝土短柱轴压力学性能的影响。研究结果表明:钢管再生混凝土短柱的变形破坏形式与普通钢管混凝土短柱相似;随再生骨料取代率及长径比的增加,钢管再生混凝土短柱的极限承载力下降。基于试验验证普通钢管混凝土短柱极限承载力计算方法对钢管再生混凝土短柱的适用性,计算值与试验值吻合较好。
Based on axially compressive tests of 6 recycled concrete filled steel tube short columns and 3 common concrete filled steel tube short columns, the influence of replacement percentages of recycled aggregate and longitude to diameter ratio on compressive capacity was studied in this paper. The test results demonstrated that the recycled concrete-filled steel tube short column and common concrete-filled steel tube short column had similar deformation and failure mode. The greater the longitude to diameter ratio and replacement percentages of the recycled aggregate, the lower the compressive capacity of specimens; the formula for the calculation of the ultimate compressive capacity of common concrete filled steel tube short column was also applicable to recycled concrete filled steel tube short column.
