摘要
本文介绍一个高效的混凝土混合结构。广州南航大厦是一幢高度超过２００ｍ的超高层混凝土建筑，采用多筒结构体系，抗侧力结构和承重结构简单合理，其中梁和剪力墙为钢筋混凝土结构，楼板采用无粘结部分预应力混凝土结构，底层承重柱为钢管混凝土柱，基础采用大直径人工挖孔桩。
A hish efficiency composite concrete structure. used for the China Southern Aitlines Building in Guangzhou City is pressented in this paper. lt is a highrise concrete structure with a height of more than 208 meters, in which the multiple tube structural system has been adopted. The lateral force resistant structure and the load bearing structure used in this building structure are simple and rational. The reinforced oncrete structures are used for beams and shear walls, and the un- bonded partially prestressed concrete slabs are used.for the typical floors. The concrete filled steel rube columns are used in the ground floor and the large diameter hand-dug caissons are used for foundation.
