Floyd County, Iowa | Without pics, I'd say you will have to brace it. If it's how I picture it in my head, the loft floor joists are acting as collar ties (similar to the bottom chord of a trussed rafter). Without these, the barn has no interior cross bracing to hold the sides in, which in turn holds the roof up. Usually the old round roof barns had knee braces, also. They were attached to the loft floor joists about 6 to 8 feet in from the wall, and went up to the arched rafter. If this is how it is, there are ways to brace it to allow the floor to be removed, but it depends on the barn design and how much you want to put into it.
Might be I'm looking at the wrong mental image in my memory bank. | |
