Question details

2a) Shown below is a section through a 30 x 15 entrance canopy. The canopy consists of a hollow structural steel beam structure supporting metal decking with roofing membrane above and wood and aluminum finish panels below. Steel rods, spaced at 20, o.с., suspend the roof canopy from a building facade The code prescribed roof snow load that the canopy must support is 29 psf. The dead load of the canopy support structure (including roofing membrane, metal decking, wood and aluminum panels, and self-weight of steel beams) is 35 psf Determine the axial load in one of the steel rod Steel Rod 9 3 12 determine the minimum required diameter of steel rod that can safely support the canopy shown above. (Round your answer to the nearest 4)
