RE: Diagonal Studs

[Subject Prev][Subject Next][Thread Prev][Thread Next]

If the vertical poles are embedded into the soil and it’s a true barn/pole structure, it should be fine provided If it doesn’t take the lateral load through the diagonal studs. Are they trying to say by installing vertical board you can create an equivalent diagonally sheathed shearwall? (i.e. allowable = 300 plf or if specially detailed 600 plf allowable?).


I agree, that the benefits (if any) don’t outweigh the problems. Are they just going to stucco over bare studs or put siding on them?


In the picture, it’s a pretty tall barn and the embedment would need to be pretty deep with big poles (steel) to make it work for wind.

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,
