Optimization of cold formed steel cross section profile for timber upgrading

The aim of this paper is to study the mechanical capacity improvement in a cold formed steel cross section with thickness of 1 mm regards to a cross section made by means of hot-rolled steel with thickness of 4 mm, respectively. Likewise, the differences are studied in the manufacturing processes used in both profiles, and the particularities of cold formed steel cross section. This paper analyzes temperature, stress and deformations using Element Method DEFORM software. This research has been focused in the study of accumulation points of stress to verify the behavior of the sheet of cold formed steel during the folded process. Stress of the steel cross section has been analyzed during the folded process, showing instant step of simulation. Conclusions show how these points of stress concentration could be an influence during the manufacturing process.
