［摘要］在大同美术馆钢结构屋盖项目中，钢结构屋盖主要采用双层网架结构，融合了拱桁架和折板体系的设计理念，把拱桁架和折板有效的搭接，形成一个整体的稳定的结构体系。主要借助SAP2000整体计算和编制的Excel后期数据处理功能，参考了中国和欧洲钢管结构规范，完成钢管结构杆件和节点设计。在复杂的钢结构设计中，能够尽可能的参考既有规范，简化计算模型，而非复杂费力的有限元分析同样能够取得有效的结果。

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.
