Breaking Like a KitKat Bar
Remember the 1990’s KitKat commercial where the chocolate bar was snapped in two?
That’s what this barn in the featured photo appears to be doing in one of the sidewalls.
But why is it snapping in two?
The out-of-square door opening shows that one length of the wall is dropping more than the other length (Figure 1).
The upward bend in the bottom chord bracing shows that the walls supporting the roof trusses are dropping more that the side walls (Figure 2).
The separation under the siding of the side walls shows that at least one post in the sidewall is also heaving upward (Figure 3).
Conclusion: The poles of the barn (Figure 3) are moving up or down unevenly due to earth movements.
Now go get a KitKat bar. You know you want one.
