［摘要］在大同美術(shù)館鋼結(jié)構(gòu)屋蓋項(xiàng)目中，鋼結(jié)構(gòu)屋蓋主要采用雙層網(wǎng)架結(jié)構(gòu)，融合了拱桁架和折板體系的設(shè)計(jì)理念，把拱桁架和折板有效的搭接，形成一個(gè)整體的穩(wěn)定的結(jié)構(gòu)體系。主要借助SAP2000整體計(jì)算和編制的Excel后期數(shù)據(jù)處理功能，參考了中國(guó)和歐洲鋼管結(jié)構(gòu)規(guī)范，完成鋼管結(jié)構(gòu)桿件和節(jié)點(diǎn)設(shè)計(jì)。在復(fù)雜的鋼結(jié)構(gòu)設(shè)計(jì)中，能夠盡可能的參考既有規(guī)范，簡(jiǎn)化計(jì)算模型，而非復(fù)雜費(fèi)力的有限元分析同樣能夠取得有效的結(jié)果。

Abstract: In the steel roof of Datong art Museum, it is mainly adopted the dual layer gridshell structure, blended arch truss and folded plate concept idea, and overlapped arch truss and floded plate together effectively, erected an integrated and stable system.  Combined overall model analysis by SAP2000 and post-data addressing by edited Excel spread sheet, referring to the structural code both China and Europe, and the steel hollow member and joint design were completed. During the complicated steelworks design, fully take advantage of the existing standards, and simplify the calculation model, rather than the finite element analysis, still can achieve the effective result.

Keywords: dual layer gridshell； arch truss； folded plate； steel hollow section； spread sheet addressing
