［摘要］高層建筑中廣泛使用鋼管混凝土柱作為結(jié)構(gòu)構(gòu)件。收集了日本1968～2013年間設(shè)計的159座高層鋼管混凝土建筑的結(jié)構(gòu)特性數(shù)據(jù)，分析了不同設(shè)計階段現(xiàn)存高層鋼管混凝土建筑的結(jié)構(gòu)布置和抗震設(shè)計參數(shù)。得到以下結(jié)論：不同階段，結(jié)構(gòu)所用的混凝土強度等級不斷提高，因此結(jié)構(gòu)的樓層數(shù)和樓層高度不斷增加；近幾年，隔震結(jié)構(gòu)和消能減震結(jié)構(gòu)的數(shù)量大幅增加；高層鋼管混凝土建筑傾向于使用和鋼結(jié)構(gòu)建筑幾乎相同的設(shè)計基底剪力系數(shù)。

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
