(東南大學(xué)建筑設(shè)計研究院 南京 210096)[提要] 南京國際展覽中心跨度75m的鋼管拱架按74.85m設(shè)計，設(shè)計時利用了結(jié)構(gòu)的變形；采用鋼管相貫焊接節(jié)點技術(shù)。該工程為今后大跨度鋼結(jié)構(gòu)的設(shè)計提供了有益的經(jīng)驗。
[關(guān)鍵詞] 大跨度鋼結(jié)構(gòu) 鋼管拱架 鋼管相貫焊接節(jié)點 風(fēng)洞試驗By considering of the structural deformation, the span of the vaulted tubular steel space truss in Nanjing International Exhibition Center is designed and manufactured as 74. 85m which is smaller than the actual one 75m. The tubularfull penetration butt-welded joint technology is adopted. This structure design method provides profitable reference for the following large span steel structure.
Keywords: large span steel structure; vaulted tubular steel space truss; tubular full penetration butt-welded joint; wind tunnel test
