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。
Steel tubular columns are widely used as structural members in high-rise buildings. The structural characteristics of 159 high-rise CFST buildings in Japan from 1968 to 2013 were collected. The structural layout and seismic design parameters of the existing high-rise CFST buildings in different design stages were collected. The conclusions are as follows: In different stages, the strength level of concrete used in the structure is increasing continuously, so the number of floors and height of the structure are increasing. In recent years, the number of isolated structures and energy dissipation structures increases greatly; Use almost the same design base shear factor as steel construction.
