Problem 2 Figures on page 3 show the partial framing plan and elevations of a three story steel structure. The floor dead load is 60 psf and the floor live load is 80 psf. The roof dead load is 20 psf and the roof live load is 10 psf. Assume that the stair load is the same as the floor load. Using the LRFD load combinations, find the: Ultimate loading for the beams B-1 through B-9, located on the second level. Ultimate loading for the beams RB-1 through RB-9, located on the roof. Ultimate loading for the girders G-3 through G-5, located on the second level. Ultimate loading for the girders RG-3 through RG-5, located on the roof. Ultimate loading for the columns G-1 through G-3, H-1, and H-2 between the first and second levels. Compare the loading in columns G-3, H-1, and H-2 by adding up the loads transferred to them from the beams and the girders they support, and the tributary areas. Maximum shear and moments for the beams B-2, B-4, G-3, and G-4, on the second level. (The loading has already been found in part a, and c from above.) (f)
