[提要] 高層和超高層建筑下部的重載柱內力巨大。廣東粵財大廈53層，柱子的軸力已經達到了144000kN，這時應視軸力大小選用高強混凝土、約束混凝土、鋼管混凝土和型鋼混凝土或其復合柱。作者介紹了我國規(guī)范中這些柱的設計方法，對于目前尚無規(guī)范可循的復合柱設計，推薦了一個非線性全過程計算機分析方法。最后，以實用設計軟件TBSA為例，探討了含有此類重載柱的結構整體分析方法。
[關鍵詞] 高層建筑 鋼筋混凝土柱 鋼管混凝土 型鋼混凝土 組合結構The axial force of a column in Guangdong Yuecai Edifice is 144 000kN. In this kind of columns,it is necessary to select from high strength concrete, restrained concrete, concrete filled steel tubes, steel reinforced concrete and composite or mixed construction according to the forces. The design methods of the columns with heavy axial loads in Chinese codes are introduced.A nonlinear full range analysis method by computer is recommended to design composite or mixed construction. Lastly, the structural analysis method for these concrete columns is discussed through a example.
Keywords: high-rise building; concrete filled steel tubes; steel reinforced concrete; composite and mixed construction: reinforced concrete column
