RE: Diagonal Studs

[Subject Prev][Subject Next][Thread Prev][Thread Next]
This building seems to be a traditional structure that was developed to take advantage of local materials and connection methods, such as wooden pegs. It seems that the lateral force is resisted by the diagonal wall studs (read bracing). The diagonal bracing is stiffened by the vertical or horizontal siding boards. A rational analysis should be able to justify the structure.

This is exactly what I want to know.  The client asked me to help him getting a building permit in nor-cal for this type of building.  I think the shear wall values in CBC/UBC is all for vertical studs (from various testing etc.).  The gravity system is easy to deal with for the post and beam system.  But the lateral system would be a tough sell.  I was just wondering if anyone has done this before in California, although I don't think seismic will govern for this type of building.

Dear Yi:
Why would a person want to have diagonal studs?
Would it be to make it easire to attach vertical siding?  This may be a plus.
Is there a desire to use it as part of the structural system?  This approach would appear to be fruitless. 
    1.  Longer studs, could mean larger studs.  Or plate height less than 8'-0"?
    2.  Seismic and wind resistance would not be enhanced.  There are no 'tested' assemblies  matching this system that I am aware of.   What shear wall deflections would you expect (calculate)?
Electrical and plumbing would be adversely effected in trying to notch and bore holes through studs.   Running sewer and vent piping on an angle would be a challenge.
What is jerry rigged for window openings, trimmer studs, etc.?
I'm curious to see if the benefits outweigh the challenges.
With Joy and Hope,
