摘要

摘要: 以内PVC管外铝合金管的中空圆铝管混凝土短柱为研究对象,考虑聚氯乙烯(PVC)管直径和铝管壁厚两个因素,对中空圆铝管混凝土短柱进行了轴压试验研究和相应的有限元模拟分析,获得了中空圆铝管混凝土短柱试件的破坏形态、极限承载力、荷载-铝管应变关系,对比分析了现有钢管混凝土轴压短柱承载力计算方法预测中空圆铝管混凝土短柱承载力的可行性。研究结果表明:中空圆铝管混凝土短柱的破坏形态表现为鼓曲型破坏;当PVC管直径不变时,随着铝管壁厚的增加,试件极限承载力提高幅度达到46.6%~96.6%;当铝管厚度不变时,随着PVC管直径的增大,试件承载力下降了8.3%~28.4%。现有的关于钢管混凝土(CFST)柱承载力的欧洲EC4规范和美国AISC规范的预测结果的准确性受到铝管壁厚的影响,且过于保守;我国CCES规范针对不同壁厚试件的预测数据稳定性存在不足;学者陶忠所提出方法的预测结果的接近程度和数据稳定性相对最好。最终提出了关于中空圆铝管混凝土短柱轴压承载力计算的建议。

Abstract: Concrete-filled double-skin circular aluminum tube short columns consisting of PVC tube inside and aluminum alloy tube outside was taken as the research object, considering two variables of PVC tube diameter and aluminum tube wall thickness, axial compression test research and corresponding finite element simulation analysis on the concrete-filled double-skin circular aluminum tube short columns were carried out. The failure modes, ultimate bearing capacities and load-strain relation of the concrete-filled double-skin circular aluminum tube short column specimens were obtained. The feasibility of using existing calculation methods for the bearing capacity of steel tube concrete short columns under axial compression to predict the bearing capacity of concrete-filled double-skin circular aluminum tube short columns were compared and analyzed. The research results indicated that the failure mode of concrete-filled double-skin circular aluminum tube short columns exhibited bulging failure. When the diameter of the PVC tube remained constant, the ultimate bearing capacity of the specimen increased by 46.6%-96.6% with the increase of the wall thickness of the aluminum tube. When the thickness of the aluminum tube remained unchanged, the bearing capacity of the specimen decreased by 8.3%-28.4% with the increase of the diameter of the PVC tube. The accuracy of the projected results of the existing European EC 4 code and the United States AISC code for CFST column bearing capacity was affected by the wall thickness of the aluminum tube and the result were too conservative. The predicted data stability of CCES standard for specimens with different wall thicknesses was insufficient. The method proposed by scholar Tao Zhong showed the best predicted results and data stability.Finally, a suggestion was put forward for the calculation of the bearing capacity of concrete-filled double-skin circular aluminum tube short columns under axial compression.
