Re: built-up wood beam

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Gary,

I've never heard of this notation either. If I were prone to wild half-assed speculation over the internet I might speculate that it means 9" wide by 11.25" deep, which would make it six 2x10; but who knows?

If it really is six 2x10 the uneven contact area of the beam bottom makes gluing suspect. And "hardwood? Why not use MicroLam? At least you would know that it was as dry as the existing beam and you would know all of the properties.

As for replacing it, the cost of shoring, etc., would make that quite expensive, I think. My suggestion would lean towards sistering it with a pair of MicroLams or steel channels to minimize the cost of labor.

Regards,

H. Daryl Richardson

List,

I have been asked to review drawings for a house addition,  The designer
has called for an existing beam (9h x 11.25v actual or nominal?) to be
reinforced with a 2" x 11.5" hardwood plank glued on the flat to the
bottom of the existing beam with an epoxy glue.  I am assuming the
original beam is S-P-F or Doug Fir as that is pretty standard around
here.  No grades or species were given. I have never heard of such a
thing and do not want to comment on it if it is acceptable practise but
it seems strange to me.  The house is approximately 20 years old.  I'm
just wanting to feel warm and fuzzy about this.

TIA,

Gary
