[摘要]青島國際航運中心主樓結(jié)構(gòu)高度254.4m,采用鋼管混凝土框架鋼筋混凝土核心筒混合結(jié)構(gòu)。從結(jié)構(gòu)體系、抗震性能設(shè)計等方面對超高層結(jié)構(gòu)設(shè)計進行了簡要論述。并對超高層建筑豎向構(gòu)件設(shè)計中的鋼管混凝土柱設(shè)計,弧形墻體設(shè)計以及徐變、收縮分析三個方面進行了詳細(xì)分析、介紹。最后提出了使結(jié)構(gòu)抗震性能目標(biāo)和豎向構(gòu)件徐變、收縮效應(yīng)落實到結(jié)構(gòu)設(shè)計的建議。

Abstract: The main building of Qingdao International Shipping Center, which has the height of 254.4 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 concrete-filled 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.
Keywords: super tall building; performance-based seimic design; concrete-filled steel tubular column; curved wall design; creep; shrinkage
