| 摘要: |
| 为促进钢-混凝土组合柱在超高层巨型框架结构中应用,在简要介绍采用钢-混凝土组合巨型柱的巨型框架结构基础上,从型钢混凝土巨型柱和钢管混凝土巨型柱两个方面综述了钢-混凝土组合巨型柱抗震关键技术研究及应用,指出了该类钢-混凝土组合巨型柱若干有待深化研究的技术问题.分析表明:巨型框架结构是一种受力性能优越的高效抗震体系,中国已建成和在建的标志性超高层建筑大多采用了钢-混凝土组合巨型柱框架结构,相关研究主要集中在弹塑性有限元分析和模拟地震振动台方面；复杂截面钢-混凝土组合巨型柱,经合理设计后具有较好的抗震性能,具有普适性的受力性能理论计算方法及合理抗震构造是亟待深化研究的关键技术问题. |

| Abstract: |
| To promote the application of steel-concrete composite columns in mega column structures of super high-rise buildings, the key seismic technology and application of steel reinforced concrete (SRC) and concrete filled steel tube (CFT) columns are reviewed on the basis of a brief introduction of the mega frame structure with steel-concrete composite mega columns. Several technical issues on the steel-concrete composite mega columns that need to be further investigated are proposed. Research shows that the mega frame structure is an effective anti-seismic system, with perfect mechanical property. The finished and ongoing super high-rise buildings mostly utilize the mega frame structure with steel-concrete composite mega columns in China. Related studies mostly focuse on elastic-plastic analysis and shaking table test. The complex cross-sectional steel-concrete composite mega columns have good seismic performance after reasonable design. The related mechanical behavior theoretical calculation method with universality and the reasonable structural constructions are the key technical issues that urgently need to be further studied. |
