Interior Shear Wall

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

We have used what we call blocking panels.  These blocking panels are spaced
every two or three truss spaces and act as shear walls.  We frame them
between the trusses and sheath them with plywood.  You have to design as
plywood shear wall and provide chords and uplift resistance.  This may work
for you if the heights are within reason.

From: richard lewis <rlewistx(--nospam--at)>

I have a question regarding using an interior bearing wall as a shear
wall.  I have a corridor wall I would like to use as a shear wall.  I
will have plywood sheathing covered with gyp. board.  I have trusses
bearing on the wall.  I broke the trusses in half to eliminate truss
uplift forces from shrinkage.  I am wondering how to get the shear down
from the roof sheathing.  How do others typically do it?  There will be a
lot of vertical members running along the wall.  I also have some very
significant shear forces because this is a church building, not
residential.  It has a large foot print.  I don't see 2x4 diagonal web
bracing to be sufficient.

Any suggestions would be appreciated.
