WOOD MOMENT FRAME

WOOD MOMENT FRAME

WOOD MOMENT FRAME

(OP)
Hi,

Is it possible to build wood moment frame ?(for residential usage,like under the roof of the balcony).
If yes,how should I connect them together and to the foundation?

Thanks in advance.

RE: WOOD MOMENT FRAME

See wood moment frame under Moment Frame and Shear Walls.

I think you would be farther ahead to use some knee bracing.

RE: WOOD MOMENT FRAME

Is this a problem where Glulam beams/arches would be appropriate.  Glulams are the only thing in wood that act like moment frames of which I am aware.  Glulams are engineered products so they will do the engineering for you, I believe, but you'll have to pay for it.

Thanks for all of your inputs,...

Dinosaur!, The G.L.B. would be fine, the only thing is designing the connections, is there a book that shows how to design wood moment frame connections ?

RE: WOOD MOMENT FRAME

Try the AITC "Timber Construction Manual" or the "Wood Engineering & Construction Handbook".

Fix the bases by embeding them in a pilaster or create a cheap moment frame by kicking the top of the column to the beam.  Make it a "truss" with K type connections into the columns.

RE: WOOD MOMENT FRAME

I have a book called "Structural Design in Wood" by Stahnaker & Harris, published by Van Nostrand Reinhold.  It appears to be a well written book covering a wide range of subjects relevant to wood design including connections.

The glulam frames I have seen in the past are actually three hinged arches.  The bottom two hinges are restrained by casting steel U-shaped pieces into a substantial concrete slab.  The arches are then set inside the U-shaped cup and lean against one another at midspan (the pak of the roof).  There are a large number of contemporary churches constructed this way beginning sometime in the 1960s.

To support a balcony, you may be able to stand one half arch up and restrain the bottom toe, but restraining the knee would be a difficult matter.  It sounds as if you want to retrofit a balcony onto an existing structure.  This makes the problem more complicated since we have to deal with the existing structure as well.  Good Luck.
