[摘要] 某工业区内一座巨型单跨单层框架-支撑体系的空间钢结构厂房，由于工艺功能上的特殊要求，结构中间3层转换桁架标高处无刚性楼板，只有顶层钢屋面为刚性楼层，因此在结构设计中提出了相应解决措施。本文简要介绍了该工程主体钢结构部分的设计，包括设计参数、结构布置、模型概化和结果讨论。

Abastract: The project is a one-bay huge braced frame steel structure located in an industry zone. Due to the special requirements in manufactory functions, there are no rigid slabs at middle floors other than the roof. Accordingly, solutions to these difficulties are proposed in the building design. Steel structure design is briefly described in this paper, including design parameters, structure arrangement, analysis model and results discussion.
