You got it Tim...
These "poor creatures" have gotten the heck knocked out of them in the century or so of standing. We even had a nice Dutch Barn and threshing barns with some "relish failure," in the "anchor beam," and "swing or bull beams."
What you might find interesting from our other part of this conversation, is in the northern areas where you find they have not pegged the braces, you can often find the barns have had small shims or wedged pounded into the brace mortise to "tighten things up." You will on occasion find this with pegged braces as well, but no wear near as often. I agree it is a personal choice, but I do believe the wedge brace is superior, (perhaps subjective?) but it can perform all the same tasks as a pegged brace, it does not require boring a peg whole, can be serviced while within the frame, and re-tightened should there be some type of tectonic event.
I have also speculated and found reference in text, oral accounts, and research, that "pegged braces" are a vestigial style from the "let in brace" common in scribe rule. This system of brace (nod to David Bahler
) was common through out the mountain regions of Europe. It is one of the few bracing systems, when executed in certain design parameters will work in both tension and compression. Though the tension capabilities are limited, these frame types, when working in concert with all given components are some of the most resistant frames ever cut to tectonic and chronological distortion.
