摘要
青岛国际航运中心主楼结构高度254.4m,采用钢管混凝土框架-钢筋混凝土核心筒混合结构。从结构体系、抗震性能设计等方面对超高层结构设计进行了简要论述。并对超高层建筑竖向构件设计中的钢管混凝土柱设计,弧形墙体设计以及徐变、收缩分析三个方面进行了详细分析、介绍。最后提出了使结构抗震性能目标和竖向构件徐变、收缩效应落实到结构设计的建议。
The main building of Qingdao International Shipping Center, which has the height of 254. d meters, adopts hybrid structural system of concrete-filled steel tubular frame and reinforced concrete core wall. The design of the super tall building was illustrated briefly in terms of structural system and performance-based seismic design. The design of concretefilled steel tubular columns, curved walls, shrinkage and creep in vertical components design of the super tall building were analyzed and introduced in details. In conclusion, further suggestions on applying seismic performance objectives and the effects of vertical components＇ creep and shrinkage to structural design were proposed.
