Is anyone familiar with such an animal? We have a building with these, and we're trying to change the use of the space, but the joists won't work with the new load. So, the questions are: a) where can I find info on such joists, and b) does anyone have any ideas on strengthening the system? Right now, we're leaning toward inserting new joists or wide flanges between the joists, but that will get costly, and will be difficult with the tight spaces. If we can somehow use the existing joists. . .
The chords appear to be light gauge channels, with hollow tube webs. The structure is a metal building, if that helps. The floor is 3 1/2" concrete on 1 1/2" form deck (5" total).
