Our firm is evaluating an existing facility that is to be used as an overflow area for a library's book collection. The facility has a cast-in-place concrete floor supported by steel beams. The box with an x in the figure represents an opening in the floor where the elevators are;

To assess whether the existing members are adequate for the new use, the team needs to know the idealized loads on the members. We have been tasked with finding the idealized live load on certain members. Assume that the entire floor, except the elevator space, will be used for stacks of books. a. Find the idealized live load on girder Al-C1. b. Find the idealized live load on girder Cl-C3.

To assess whether the existing members are adequate for the new use, the team needs to know the idealized loads on the members. We have been tasked with finding the idealized dead load on certain members. The concrete floor weighs 150 psf and carries a superimposed dead load of 10 psf for utilities and flooring. The beams all weigh about 100 plf. a. Find the idealized dead load on beam A2-C2. b. Find the idealized dead load on girder Al-A3.
