Core filled steel columns

Core filled steel columns

Hey Everybody,

Does anyone have any design guidelines that includes fire-resistance performance?  I'm currently using a 2002 Onesteel (Australian steel manufacturer) paper, but it's not very useful for any columns taller then 2m.

Thanks,
Paul

RE: Core filled steel columns

I have always run with the assumption that grout filling a steel tube increases the fire resistance period (FRP) but have never found concrete evidence of what FRP it is increased by.

RE: Core filled steel columns

CIDET (Europe) has done a lot of research into this.  In addition, the old Stelco has a publication on this, if you can dig up a copy.

Hi

The National Building Code of Canada and the Canadian Design of Steel Construction Standard (Limit states design of Steel Structures CAN/CSA S16-01) both have instructions and formulas for that topic.

Good luck.

RE: Core filled steel columns

Could you be a little more specific, StrucConsultant?  What article?  I looked for it but couldn't find it.

Thanks all for the links and info.  Given me quite a bit to get through.

Hey again, has anyone reviewed "Design guide for structural hollow section columns exposed to fire" by L. Twilt, R. Hass et al?

I'll have to find it, I don't have that with me here.  We've done some buildings a few years back with those columns. I'll let you know.

Thanks StrucConsultant

RE: Core filled steel columns

Here we go :

National Building Code - Canada 2005
Volume 2
Division B
Appendix D
D-2.6.6

AND

CAN/CSA S16-01 - Limit States Design of Steel Structures
18.2

I hope this will help.
