The 4-story building has a floor and roof dead load D = 70 psf, floor live load, L = 100 psf. The length of columns is 25 ft and the column ends are pins (Lx = Ly = 25 ft). 1) Determine Pu on interior columns B2-4 and B2-1 2) Use Table 4-1a (p. 4-12 to 4-24) in AISC to select the lightest W shapes for these columns 3) Use Table 4-4 (p. 4-69 to 4-84)in AISC to select lightest square HSS shape for the columns. 30 ft 44 30 ft 30 ft 30 ft Column B2-1 Column B2-4
