[摘要] 某工業(yè)區(qū)內(nèi)一座巨型單跨單層框架-支撐體系的空間鋼結(jié)構(gòu)廠房，由于工藝功能上的特殊要求，結(jié)構(gòu)中間3層轉(zhuǎn)換桁架標(biāo)高處無剛性樓板，只有頂層鋼屋面為剛性樓層，因此在結(jié)構(gòu)設(shè)計(jì)中提出了相應(yīng)解決措施。本文簡要介紹了該工程主體鋼結(jié)構(gòu)部分的設(shè)計(jì)，包括設(shè)計(jì)參數(shù)、結(jié)構(gòu)布置、模型概化和結(jié)果討論。

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.
Keywords: huge one-bay structure,frame-brace system,transformation truss,high-rise steel structure
