snow load Featured

and sadly the old Albion did NOT have a "truss" roof and the "bones" were about 150 years? old. It was likely only about half as strong as the day it was built. Hope they can get someone like MarSpan to get a set of trusses put together and shipped over pretty quick to get it weather-tite before too much more snow comes down.

Are there no local craftsmen capable of building trusses ? I copied designs from online and built my own and I don't consider my self to be a carpenter ... BTW , these were designed for at least 5 times the average snow load for our area . The scissor trusses for the vaulted ceiling in the dining room/kitchen area were the most fun .

They are all over in France working on the cathedral. Amazing what they have done.

Yes there are - MarSpan. The trusses must be engineered for the application - this is a commercial building - and even residential trusses need to be "signred off". We have more stringent regulations up here - need to be designed for snow load and wind - among other things. - and these are not "small" trusses either.

Mine aren't what I'd call "large" , I'm only spanning 24 feet . These are exact copies of some I found on a truss design website . The only difference is I used plywood instead of press plates . Out in the county where we live there aren't any building codes as such . I have a tendency to over engineer stuff especially where weight isn't a big consideration . Doubled 2x12 floor beams instead of 2x10 and supported every 8 feet instead of 10 , etc .
