［摘要］廣州西塔采用鋼管混凝土斜交網(wǎng)格外筒+鋼筋混凝土筒體的結(jié)構(gòu)體系。根據(jù)斜交網(wǎng)格外筒的受力特點(diǎn)，采用了體外預(yù)應(yīng)力抵抗樓層產(chǎn)生的平面內(nèi)拉力。對(duì)體外預(yù)應(yīng)力的設(shè)計(jì)及施工控制進(jìn)行了詳盡的介紹。分析及施工監(jiān)測(cè)表明，采用體外預(yù)應(yīng)力取得了良好的效果。

Abstract:Guangzhou West Tower is of the structure system with CFT diagrid outside and reinforced concrete core inside. The character of CFT diagrid tube creates tension in the floor plane, and in order to resist the tension in floor plane, external prestressed component is adopted. The design of external prestressed structure and construction are introduced. The results of analysis and construction supervision show that the external prestressed system has good effect.
Keywords:super-tall building; diagrid tube; external prestressed; construction supervision
