Hody!
I'm currently designing timber structures-columns, beams and so one. But I would like to know how do design timber structure fire resistance.
Any literature or standards that could help me?
Thanks!

Or even better perhaps some examples.
Thanks

Pretty sure this is covered in the IBC and relevant local codes for 'Heavy Timber Construction'. I believe it specifies minimum sizes for members and decking and varies on use category, safety features (sprinklered?), number of occupants, gross square footage, etc.

What is IBC?

International Building Code, the ICC commercial code, as opposed to the IRC, the International Residential Code for single family residences.

hi nitram, don't put a bunch of kindling in the living room.

Very large chamfers.

Wane makes for large chamfers, but they have a higher sap content, what does that do for ignition?

As I recall, old fireplace lintels and wooden mantels were always built w/ chamfered edges.

Sharp edges have a smaller "cross section" (mass) and therefore heat up easily. The thinner edges could then ignite, thus lighting up the whole timber.

My home town (seems to be coming up alot lately) is ten miles downriver from this mill complex, it's full of heavy timber, Doug at that, NE was largly deforested of big timber at this point.

And it's full of chamfers. They are not for pretty, they're for fire.

Most of the corporation buildings are still there.
