- Design a typical girder for the floor system shown in the figure below. In addition to the weight of the beam, the dead load consists of a 5-inch-thick reinforced concrete slab (normal-weight concrete). The live load is 85 psf, and there is a 20-psf partition load. Do not check deflections. Assume that the girder is supporting beams on each side, and assume that the beams weigh 35 lb / ft. Let all the loads on the girder act as a uniform load (be sure to include the weight of the beams). 30' A -4 @ 5' = 20' Use the table below. - Mn (ft-kips) Mn/ (ft-kips) | Vn (kips) Vn/v (kips) Shape W21 × 48 398 265 216 144 W12 × 58 324 216 132 87.8 W16 × 45 309 205 167 111 W18 × 40 294 196 169 113 a.
