The structural member of the vault is welded thin-wall box components. The steel structure design of the vault is introduced emphatically. The effect of contorted shape on welded thin-wall box components and the arrangement of the stiffening rib on the welded thin-wall box components under tension, compression, bending and twisting are analyzed and researched by computing and experiments.Keywords: museum; steel structure; vault; contorted wall box components; welded thin-wall box components; stiffening rib作者简介:高昂,硕士,工程师,Email:gaoangbiad@sina.com。参考文献[1]范重,范学伟,刘岩 焊接薄壁箱型构件在国家体育场中的应用研究[J]. 工程建设与设计,2005(4).[2]GB50017—2003 钢结构设计规范[S].北京:中国计划出版社,2003.[3]范重,彭翼,王NFDA1,等. 国家体育场主结构扭曲箱梁构件设计研究[J]. 建筑结构学报,2006,27(2).[4]陈绍藩. 钢结构设计原理(第二版)[M].北京:科学出版社,2001.[5]范重,范学伟,刘先明.焊接薄壁箱型构件设计方法研究[J].建筑钢结构进展,2006,6(3).
