摘　　要：在大跨空间钢结构的推广应用中,设计人员为了节省用钢量和降低结构造价,往往对结构的局部杆件进行抽空简化.着重分析了网壳的几种抽空方式的受力和变形性能,对几种抽空方式进行了综合比较,并对抽空后的加强技术提出了3种方案.In the application of long-span steel structure, in order to economize the steel consumption and reduce the structure cost, designers usually carry out the evacuation and simplification on local trusses of the sturcture. This paper focuses on analyses of the stress-deformation performances of several barrel shell evacuation modes, makes comprehensive comparisons between the modes and presents three plans for the reinforcement technology after evacuation.
