摘要

制作了10个相同含钢率的矩形钢管混凝土短柱,按不同的偏心率进行加载试验,研究了相同含钢率条件下矩形钢管混凝土短柱的承载力与偏心率间的关系。结果表明,矩形钢管混凝土短柱在加载过程中具有较好的塑性,随着偏心率的增大,构件极限承载力明显下降,试验结果与承载力理论计算结果进行了比较,二者基本一致。
Ten short columns with concrete-filled rectangular steel tube with the same steel quantity are made,and are tested by different eccentricity.The load-carring capacities of the short columns with concrete-filled rectangular steel tube v.s their eccentricities under the same steel quantity are investigated.Results show that the short columns with concrete-filled rectangular steel tube are of better plasticity in the procedure of load added and their limit capacities manifestly decrease with increase of eccentricity.Experimental results are in good line with those calculated.
