We've a common problem in the north east, hay tracks. They would tell farmers to remove queen ties to accomadate hay tracks and roof loads went right to the plates and overloaded the tie beam/ post connections. Many smaller frames , like carriage barns had no rafter support system at all. Most agr. buildings in this area where not deep and pegged brace which agravated the design flaw. Then the iron man was called.
I have used steel and with a little artistic flare in can greatly compliment your work.
