Abstract
Industrial cold-formed steel racks have semi-rigid joints between the columns and beams. Frame analysis of such structures call for special considerations that are studied in this paper. The current design approach uses a linear idealization of the moment-rotation relation relationship based on an empirically decided secant to the nonlinear moment rotation curve. This study presents a refined analytical approach to the analysis such frames using the state-of-art finite elemen t based nonlinear analysis program LARSA 4D. Parametric studies are carri ed out to obtain an accurate design approach for usin g computer programs that treat linear moment-rotation relationships.

Frame Analysis and Design of Industrial Cold-formed Steel Racks
Industrial cold-formed steel racks have semi-rigid joints between the columns and beams. Frame analysis of such structures call for special considerations that are studied in this paper. The current design approach uses a linear idealization of the moment-rotation relation relationship based on an empirically decided secant to the nonlinear moment rotation curve. This study presents a refined analytical approach to the analysis such frames using the state-of-art finite elemen t based nonlinear analysis program LARSA 4D. Parametric studies are carri ed out to obtain an accurate design approach for usin g computer programs that treat linear moment-rotation relationships.
