Question

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

Answer: Beam A: 960 lb each end; beam B: 1920 lb each end; beam C: 960 lb each end
Solution
The total load (live + dead) acting in the current floor is shared by three beams in total.
