For the floor system shown in Figure 3.13, assume that the combined live and dead load that is present is equal to 80 lb>ft 2 . Assume a beam span of 16 ft and a beam spacing of 3 ft. Determine the reactions for beams A, B, and C in the floor system. (First, determine the load strip widths, then determine the appropriate loading model for each beam, and finally determine reactions for each beam by a statics analysis.)
Answer: Beam A: 960 lb each end; beam B: 1920 lb each end; beam C: 960 lb each end
