Hi,
Further to my earlier post re windbrace buckling I have just come across a photo of a barn aisle (wall) brace that illustrates how brace buckling and failure can and does take place.
The curved brace on the right has bent out of plane and then fractured in the centre as result of deformation of the whole barn frame. This barn has been rebuilt and reinforced in places (wall plate) and is beginning to show the ravages of time.
