摘　　要：螺旋焊接方钢管短柱轴压试验 ,素混凝土短柱轴压试验 ,和螺旋焊接方钢管混凝土短柱试验等三组试验表明螺旋焊接方钢管混凝土轴压短柱的极限承载力将大于螺旋焊接方钢管短柱和素混凝土短柱轴压承载力之和 30 %以上。通过将螺旋焊接的方钢管混凝土短柱轴压试验和直四缝方钢管混凝土短柱轴压试验结果的对比 ,发现前者的性能和后者相当 。Three groups of stubs, which are spiral welded rectangular steel stubs, rectangular concrete stubs, and concrete filled spiral welded rectangular steel stubs are loaded axially. The results show that the ultimate bearing capacity of the last group is substantially larger than the sum of the ultimate bearing capacity of the first two. The results of this test are compared with the test of axially loaded concrete filled rectangular steel stubs with four longitudinal welds at four corners. It is found that the performance of the former is equivelant to or better than the latter.
