Story drift!
Story drift!
(OP)
I am designing steel moment frames for a steel building - one story. What is the story drift limitation per AISC for steel buildings? I heard it is H/400, however, I could not find this requirement in AISC. I would appreciate help.

Check out AISC Design Guide #3 - Serviceability Design Considerations for Steel Buildings
RE: Story drift!
Per AISC, 13ed, section L4 (pp. 16.1-144), it reads as .................... shall not exceed the limiting values of such drifts that may be specified by the applicable BLDG code. Do you know if IBC has this limitation specified? If yes, which section?
RE: Story drift!
One reference that I have gives the following design recommendations based on what type of exterior cladding or interior partions you have:
Exterior cladding:
Brick veneer or unreinforced concrete = L/400 to L/600
Tilt-up concr = L/200
Plaster / Stucco = L/400
Architectural Precast concrete, stone clad = L/400
Interior Partitions:
Drywall / plaster = L/400
Unreinforced masonry = L/667
Reinforced Masonry = L/400
Tile, Hollow clay brick = L/2000
Brick = L/1250
Also, your elevator may require drift control as well. To me this would be based on input from the mechanical guys. But, the design guide recommends L/400.

I would be interested in looking at your reference book.
