Abstract: The layout and design of the purlins of the lightweight steel roofing structure plays an important role in the safety and economy of the whole structure. In order to provide optimal recommendations that can be used in the design of purlins, the software STS was employed for comparing and analyzing of the steel consumption by considering the aspects of material, section types, purlin spacing, and continuity based on the newly published specifications of 2012Technical specification for steel structure of light-weight buildings with gabled frames（CECS 102:2002) and Technical code for design of cold-formed thin-wall steel structures (GB 50018—2002).
Keywords: purlin； steel structre； optimal design； steel consumption
