In town we have at least one remaining 2 story work shop. It's a corner lot on a hill. Instead of constructing ramp, access to upper floor is around the corner [uphill]. Been a mechanics shop forever. It's probably always been, but first maybe truck, tractor, or stationary engine clientele - go in to first floor it's clear. I'm guessing 12" or 14" X braced timbers on narrow [not 24"] centers. The uprights, not exactly studs, are big too; every other one is gusseted to the trusses too.

In comparison, my 16 foot ceiling was supported with 15 8" x 8"s, three rows 15 feet apart. The perimeter walls are brick, where eaves terminated 2" x 8" joists and trusses. Finally got rid of entire roof and ignorant 2":12" pitch with fabricated 4":12"s.
I saved part of the original ridge beam. It had lapped & bolted joints with pier washers to make up it's 100' length. It gusseted center posts with mitered timbers, like the secondary beams did.
