Offices. 2-6. Determine the tributary widths and tributary a of the joists, beams, girders, and columns in the roof framing plan shown in Figure 2-15. Assuming a roof dead load of 30 psf and an essentially flat roof with a roof slope of 4 in./ft. for drainage, determine the fol- lowing loads using the ASCE 7 load combinations. Neglect the rain load, R, and assume the snow load, S, is zero: a. Uniform dead and roof live loads on the typical roof beam in pounds per foot. cal roof girder in pounds per foot. column in pounds. b. Concentrated dead and roof live loads on the typi- c.
