Allowable Story Drift

[dcredskins]

What is the maximum allowable story drift per AISC? Which section of AISC 13ed Manual talks about it? I would appreciate your response.

 

[JAE]

Section L4.

Otherwise, for seismic, use the ASCE 7 limits.

I don't believe AISC addresses issues such as this. You should go to the building code.

JAE, it is for wind.

nutte, do you know if IBC 2006 address this issue?

 

[JAE]

OK..I'll bite. I now suppose you are asking about drift for seismic (your post didn't mention either wind or seismic).

 

[nutte]

I don't know exactly where to look in the IBC. I've checked before, but I've never had much luck.

Drift limits for wind depend on what cladding you are using, similar to seismic. I often us h/400 for the 10 year wind as the design criteria for wind.

Drift limits will depend upon the materials of construction: brick, CMU, glazing, drywall, metal panel, PEMB, etc. It will also depend upon joint placement.

See AISC Steel Design Guide Series 3: Servicability Design Considerations for Low Rise Buildings.

The ASCE Journal of Structural Engineering had an article in either 1998 or 1988 (there's a smudge on the reference page I'm reading) that is titled, "Wind Drift Design of Steel Framed Buildings: State of the Art Report, Vol 114, No 9, September.

I haven't read it, but it sounds like it might be a good refernce for you.

JoshPlum - Do you think you could scan that article and post it here? I looked at the Journal of Structural Engineering website and they only have available back issues to 1990 on the website. I am designing a low-rise steel building right now and would be interested in reading it.

My old professor Finley Charney was working on an update for wind drift design of steel buildings

http://www.celes.ictas.vt.edu/Drift/index.htm

It will be a good document when it comes out.

Sorry, I don't actually have a copy of that article ("Wind Drift Design of Steel Framed Buildings: State of the Art Report).

I was reviewing a draft of a new AISC design guide (on stabilty design of steel structures) that talked a little bit about drift in the appendix. Basically the same stuff that others reported (drift limits will often be based on cladding, et cetera). However, the appendix went on to reference that document.

I interested in the subject and would like to obtain a copy of the article at some point. But, I'm a California guy and don't really have an immediate need for wind drift control.
