Load Requirements for Catwalks

Load Requirements for Catwalks

Load Requirements for Catwalks

(OP)
Any information regarding loading requirements for catwalks will be appreciated.

RE: Load Requirements for Catwalks

What application?

Check the building codes, OSHA, perhaps other industry standards as applicable.

RE: Load Requirements for Catwalks

40 PSF in 2006 IBC Table 1607.1

RE: Load Requirements for Catwalks

That being for "Assembly areas and Theaters" in my 2003 IBC.  But I've seen "catwalk" used in pretty generic ways, as in industrial applications.

RE: Load Requirements for Catwalks

(OP)
It is for an Assembly area/Theater and it is adequate for up to 100 psf.  

Thanks everyone

RE: Load Requirements for Catwalks

Big difference between industrial, commercial and public use catwalks.  If in a theater and the catwalk could be loaded up with groupies, cast or crew then 40psf or even 100 psf may be light.  Adding a few pounds or even tons of steel is small compared to the issues if a failure occurs and people are hurt.

RE: Load Requirements for Catwalks

(OP)
NO GROUPIES. It is for a School with very little acces to anyone other than the maintainance people. The architect did not even want a guardrail but we provided one.

Thanks for the warning.

RE: Load Requirements for Catwalks

Use a live load of 40psf [1.92kN/m2] as per ASCE 7-98

RE: Load Requirements for Catwalks

You may be (mildly) interested to know that on this side of the Atlantic, the British Standard specifies not a udl but a series of point loads on a cat-walk of 1kN (approx 220lb) at 1m centres.
