The structure is consisted of 48 specimens of radial frameworks, 4 specimens of normal frameworks, 16 groups of V-shaped columns decorated in the external facade. In order to satisfy the vision requirements and enough audience numbers, the building facade tilts outward up to 32°, so tension force exists in the floor component. There is a few link members between the outer V-shaped columns and the grandstand structure, stability analysis should be studied. Seismic joint and expansion joint were not arranged on the grandstand structure which can not be easily divided into several stable separated substructures. Steel reinforced V-shaped concrete columns are the key members in the whole structure, the geometry relationship of the joints is complex, so the suitable steel reinforced joints are proposed.Keywords: National Tennis Court; grandstand structure; floor in tension; V-shaped column; steel reinforced concrete component; steel reinforced concrete joint作者簡(jiǎn)介:范學(xué)偉,博士,教授級(jí)高級(jí)工程師, Email:fanxuewei@pdiwt.com.cn。參考文獻(xiàn)[1]范重,范學(xué)偉,趙長(zhǎng)軍,等. 國(guó)家網(wǎng)球館“鉆石球場(chǎng)”結(jié)構(gòu)設(shè)計(jì)[J]. 建筑結(jié)構(gòu),2013,43(4):1-9,18.[2]中國(guó)建筑設(shè)計(jì)研究院. 國(guó)家網(wǎng)球館結(jié)構(gòu)抗震超限審查報(bào)告[R]. 北京:中國(guó)建筑設(shè)計(jì)研究院, 2009.[3]陳以一,張大照,薛偉辰,等. 承載開閉鋼屋蓋的預(yù)應(yīng)力混凝土看臺(tái)結(jié)構(gòu)抗震性能研究[J]. 土木工程學(xué)報(bào),2007,40(8): 22-28.[4]范重,趙長(zhǎng)軍,李麗,等. 國(guó)內(nèi)外開合屋蓋的應(yīng)用現(xiàn)狀與實(shí)踐[J]. 施工技術(shù), 2010, 39(8): 1-7.[5]范重,彭翼,胡純煬,等.開合屋蓋結(jié)構(gòu)設(shè)計(jì)關(guān)鍵技術(shù)研究[J]. 建筑結(jié)構(gòu)學(xué)報(bào), 2010, 31 (6):132-144.[6]范重,王義華,欒海強(qiáng). 開合屋蓋結(jié)構(gòu)設(shè)計(jì)荷載取值研究[J]. 建筑結(jié)構(gòu),2011,41(12):39-51.[7]GB 50010—2002 混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范[S].北京:中國(guó)建筑工業(yè)出版社,2002.[8]GB 50009—2001 建筑結(jié)構(gòu)荷載規(guī)范[S]. 2006年版. 北京:中國(guó)建筑工業(yè)出版社,2006.[9]GB 50011—2001 建筑抗震設(shè)計(jì)規(guī)范[S]. 北京:中國(guó)建筑工業(yè)出版社, 2001.[10]范重,王大慶,唐杰,等.唐山國(guó)際會(huì)展中心超長(zhǎng)大跨度預(yù)應(yīng)力結(jié)構(gòu)設(shè)計(jì)[J].建筑結(jié)構(gòu),2006,36(1):56-63.
