Assume framing elements are equally spaced between column grids. The roof framing supports a metal roof deck that supports roofing (insulation + EPDM roof). assume all elements are simply supported (pinned, roller boundary conditions). On the figure below For the framing element 20K3 identified “1B” on the figure, what is the tributary width for that element? _________________________________________________units: _____________________ For the framing element identified “1B” on the figure, if the total load applied to that element is w = 400 pounds per linear foot, what is the reaction at each end?
