［摘要］隨著用地成本在開發(fā)成本的比例逐年升高，樓宇高度日漸增加。使用面積率逐漸成為開發(fā)商重點關注的指標。以深圳華潤前海中心項目5棟160～300m的高層塔樓柱的設計為案例，通過對比幾種不同類型柱在該項目中的經(jīng)濟性指標，介紹了使用鋼管混凝土疊合柱實現(xiàn)較好的結構經(jīng)濟性和較高使用面積率的方法；總結了鋼管混凝土疊合柱的技術特點和在高層建筑設計中的優(yōu)勢，并根據(jù)施工現(xiàn)場反饋，總結了鋼管混凝土疊合柱設計和施工中的經(jīng)驗教訓，為鋼管混凝土疊合柱在超高層建筑設計中的應用提供了經(jīng)驗和方法。
［關鍵詞］超高層建筑； 使用面積率； 鋼管混凝土疊合柱； 經(jīng)濟性

Abstract:As the proportion of land use cost in development cost increases year by year, building height increases day by day. The usage area ratio has gradually become the focus of developers. Taking the design of columns of five 160~300m high-rise tower in Shenzhen CRland Qianhai Center project as an example, the economic indicators of several different types of columns in the project were compared. The method of using STRC columns to achieve better structural economy and higher usage area ratio was introduced, and the technical characteristics of STRC columns were summarized as well as the advantages of STRC columns in high-rise building design. Per feedback from construction site, the experience and lessons in the design and construction of STRC columns were summarized, providing experience and methods for the application of STRC columns in super high-rise building design.
Keywords:super high-rise building; usage area ratio; STRC column; economy
