Abstract：
As a state-of-the-art building structure, cold-formed thin-wall steel structure has various favorable performances and has witnessed its preliminary development in China. But its high cost produces limitation to its further promotion and application. With introduction of the construction of cold-formed thin-wall steel structure residential building in Beichuan County, construction cost of the structure is analyzed and it is compared with residential building of traditional structure. Characteristics of construction cost of cold-formed thin-wall steel structure are understood. Preliminary strategies are proposed to reduce the construction cost and to provide references for application of such structural system.
