［摘要］廣州塔外筒斜柱和斜撐在一橢圓直紋面上，軸線相交，而環(huán)桿通過與斜柱相貫伸出的牛腿連接形成傾斜的橢圓環(huán)，環(huán)桿通過牛腿對外筒施加約束。外筒節(jié)點必須設(shè)計成剛性節(jié)點，才能滿足整體穩(wěn)定和局部穩(wěn)定。主要介紹了剛性節(jié)點及剛性節(jié)點的試驗驗證、節(jié)點的設(shè)計構(gòu)造及有限元分析。［關(guān)鍵詞］廣州塔；剛性節(jié)點；典型節(jié)點；非典型節(jié)點；有限元分析中圖分類號：TU398-7文獻(xiàn)標(biāo)識碼：A文章編號：1002-848X(2012)06-0016-06Analysis and design on frame tube joints of Guangzhou TowerWang Weiming, Zhou Ding, Yang Hanlun, Yu Yonghui, Xiong Wei(Guangzhou Design Institute, Guangzhou 510620, China)Abstract: The frame tube structure of Guangzhou Tower is composed of inclined column, bracing and inclined elliptical ring. The axes of the inclined column and the bracing are intersected. The elliptical ring connects the oblique column with the bracket stretched out the column, and imposes constraints to the inclined column. In order to meet the overall stability and local stability requirements, the joints of the frame tube must implement rigid connection. The experimental verification of the rigid joints, the construction of joints and finite element analysis results were described.Keywords: Guangzhou Tower; rigid joint; typical joint; atypical joint; finite element analysis作者簡介：王偉明, 高級工程師, Email: wwm@gzdi.com.參考文獻(xiàn)［1］熊偉，周定，王偉明.廣州塔結(jié)構(gòu)穩(wěn)定性設(shè)計分析［J］.建筑結(jié)構(gòu)，2012，42（6）：13-15.［2］廣州新電視塔鋼結(jié)構(gòu)典型節(jié)點靜力試驗研究報告［R］.上海：同濟(jì)大學(xué)土木學(xué)院建筑工程系鋼與輕型鋼結(jié)構(gòu)研究室.
