摘　　要：为适应超高层建筑平面设计需要,工程设计单位提出了一种异形截面巨型柱框架结构,并在多个超高层建筑巨型结构中应用,取得了良好效果。介绍了巨型结构体系及受力特点,结合多个大型复杂超高层建筑工程实际,分析了异形截面巨型柱框架结构的研究概况,包括在异形截面巨型柱框架结构抗震研究方面取得的进展,提出了该类结构发展的若干有待深化研究的技术问题。分析表明:"巨型柱框架-组合核心筒-伸臂桁架"结构体系,是一种受力性能优越的高效抗震体系;异形截面巨型柱框架结构,具有良好的抗震性能,异形截面巨型柱合理抗震构造是亟待深化研究的关键技术问题。In order to meet the graphic design requirement of high-rise buildings, the design institute proposes the mega-frame structure with special-shaped columns which has been applied to several super high-rise buildings and achieved a good result. In this paper, the concept of the mega structure system and its mechanical characteristics are introduced; by the combination of several large and complex super high-rise buildings, the research situation of the mega-frame structure with the special-shaped columns including the progress made in seismic aspect by the research group is analyzed; several technical issues needing further researching of the mega-frame struc- ture are proposed. Research shows that the mega-frame-composite core walls-outrigger truss structure system is an effective and anti-seismic system which has the perfect mechanical property and the mega-frame structure with the special-shaped columns possesses good anti-seismic performance, so how to achieve the reasonable structure of sDecial-shaDed mesa columns is the key technical issue for further study.
