［摘要］某超高層建筑地上28層，建筑高度117m，為超高層辦公建筑。建設單位提出室內(nèi)凈高3m的品質(zhì)需求,且規(guī)避結構超限。經(jīng)比選，樓蓋采用鋼梁+壓型鋼板組合樓蓋,結構體系采用矩形鋼管混凝土框架-鋼筋混凝土核心筒混合結構。針對工程樓蓋跨高比較大的特點，重點探討了塔樓的結構體系及樓蓋體系設計與凈高配合設計間的要點、難點。通過組合梁及跨中加腋的措施,保證了樓蓋滿足結構正常使用極限狀態(tài)，同時也實現(xiàn)了建筑凈高的要求。
［關鍵詞］超高層建筑； 矩形鋼管混凝土框架； 鋼筋混凝土核心筒； 核心筒連梁； 大跨樓蓋

Abstract:A super high-rise building with 28 stories above ground and 117m in height, is a super high-rise office building. The construction company put forward the quality requirement of indoor clear height of 3m, and evaded the out-of-code conditions in structural codes. Through comparison and selection, the floor adopts steel beam and profiled steel plate, and the structural system is composed of rectangular concrete filled steel tubular frame and reinforced concrete corewall. In view of the large span-height ratio of the engineering floor, the key points and difficulties between the structural system of the tower and the design of the floor system and the clear height matching design were discussed in detail. Through the measures of composite beam and axillary in mid-span, the floor could meet the limit state of normal use of the structure, and the requirement of clear height of the building was also realized.
Keywords:super high\|rise building; rectangular concrete filled steel tube frame; reinforced concrete corewall; corewall coupling beam; large-span floor
