摘　　要：本文报导了10个不同套箍指标的钢管高强混凝土短柱试件的试验研究。研究结果表明,钢管高强混凝土的工作机理和破坏形态与普通钢管混凝土基本相同,但由于高强混凝土和普通混凝土本身的差异,使得钢管高强混凝土与普通钢管混凝土在性能上又不完全相同。根据试验结果,本文给出了适用于钢管高强混凝土的强度计算公式。This paper reports the experimental research of 10 specimens of short steel tubular columns filled with high-strength concrete, which have different confinement index. Research result shows that the working mechanism and failure pattern of steel tubes filled with high-strength concrete are similar to those of normal concrete-filled steel tubes, but the behavior of them are not fully same because of the difference between high-strength concrete and normal concrete. According to the research result, a formula for predicting the ultimate strength of steel tubes filled with high-strength concrete is proposed.
