［摘要］高层建筑中广泛使用钢管混凝土柱作为结构构件。收集了日本1968～2013年间设计的159座高层钢管混凝土建筑的结构特性数据，分析了不同设计阶段现存高层钢管混凝土建筑的结构布置和抗震设计参数。得到以下结论：不同阶段，结构所用的混凝土强度等级不断提高，因此结构的楼层数和楼层高度不断增加；近几年，隔震结构和消能减震结构的数量大幅增加；高层钢管混凝土建筑倾向于使用和钢结构建筑几乎相同的设计基底剪力系数。

Abstract:Concrete-filled steel tubular (CFT) columns have become popular as structural members in high-rise buildings. Data on the structural characteristics of 159 high-rise CFT buildings designed from 1968 to 2013 were collected. The structural planning and seismic design value of existing high-rise CFT buildings were analyzed as a function of their design generation. The following observations were made.The strength of concrete used in structures increased over time. As a result, the number of stories and story height increased.In recent years, seismic isolation structures and seismic structures with energy dissipation devices have largely increased in number.High-rise CFT buildings tend to use an almost equal design base shear coefficient as that of steel buildings.

Keywords:high-rise building in Japan; CFT; structural characteristic
