熊偉，周定，王偉明 （廣州市設計院， 廣州 510620）［摘要］廣州塔總高600m，為目前世界最高的電視塔。利用ANSYS計算模型對廣州塔結構進行了穩(wěn)定性分析，找到了影響結構穩(wěn)定性的主要因素，即外框筒節(jié)點剛度和透空區(qū)長度。通過對比分析，提出了外框筒剛性節(jié)點設計要求和合理的透空區(qū)支撐布置方式，并采用考慮初始缺陷的非線性穩(wěn)定分析方法對結構進行了穩(wěn)定分析。通過試驗驗證了設計的合理性，保證了結構的安全性。［關鍵詞］廣州塔；剛性節(jié)點；穩(wěn)定；非線性中圖分類號：TU398-7文獻標識碼：A文章編號：1002-848X(2012)06-0013-03Design and analysis on structural stability of Guangzhou TowerXiong Wei, Zhou Ding, Wang Weiming (Guangzhou Design Institute, Guangzhou 510620, China)Abstract: Guangzhou Tower is 600m high, which is the tallest TV tower in the word at present. It is found that the joint rigidity of out-frame tube and the length of un-braced zone are the major factors that influence the structural stability according to structural stability analysis by the ANSYS. Based on the comparative analysis, the design requirement of joint rigidity of out-frame tube and reasonable bracing arrangement were presented. Also, nonlinear stability analysis considering initial defect and tests were performed to guarantee the safety of the structure.Keywords: Guangzhou Tower；rigid joint；stability；nonlinear作者簡介：熊偉，博士，Email:gzdixw@yahoo.com.cn.參考文獻［1］周定，韓建強，楊漢倫，等．廣州塔結構設計［J］．建筑結構，2012，42(6)：1-12.［2］熊偉，周定，楊漢倫，等．廣州新電視塔天線與主塔體連接方案設計分析［J］．建筑結構學報，2010，31(1)：94-100.［3］陳紹蕃，顧強. 鋼結構［M］. 北京：中國建筑工業(yè)出版社，2003.［4］GB 50135—2006 高聳結構設計規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2006.
