Structural performance of steel and concrete composite columns was investigated by carrying out of experimental 1 work. The section of the composite columns is concrete and encased steel covering by steel tube. Shape of cross section of encased steel, width-thickness of steel tube and axial load ratio were selected as the main experimental parameters.From the test results, the following points were made clear;1) The composite columns encased little flexural strength steel shows large structural performance under axial load ratio 0.4 times against the axial compressive strength.2) The composite columns encased large flexural strength steel shows stable behavior under axial load ratio 0.6 times against the axial compressive strength.3) The composite columns covered by a thin steel tube (width-thickness ratio =125) shows large earthquake resistant properties.4) The strength of concrete was made large by an encasing cruciform steel section and covering by a thin steel tube (width-thickness ratio is 125).

通过实验1的工作，对钢与混凝土组合柱的结构性能进行了研究。组合柱截面为混凝土、钢管包钢。选择包钢截面形状、钢管宽厚和轴载比作为主要试验参数，从试验结果可以看出：1）包钢少的组合柱抗弯强度大在0.4倍轴压比下的结构性能。2）包裹大抗弯强度钢的组合柱在0.6倍轴压比下表现出稳定的性能。3）由大抗弯强度钢包裹的组合柱在轴压比0.6倍下表现出稳定的性能。薄钢管（宽厚比=125）显示出较大的抗震性能。4）通过包围十字型钢并用薄钢管（宽厚比为125）覆盖，提高了混凝土的强度。
