Patio Structure [RE-wrenches]

[Darryl Thayer]

Hi
I have built a few, The problem I find is shear
strength. If the Patio structure is attatched to the
house or other structure the shear is handled by the
other structure.  If the patio structure is free
standing the cost or the columns and foundation is
increased. 

I am an OK carpenter not a structural engineer, so I
can,t sign any prints.
