Ayuh,.... That's what I see,..... Put the beam in, then jack under it,....
Go alittle, 'n then check, Everywhere to see how it's movin' up, 'n if it's doin' it where ya want it too,...
Ayuh,.... That's what I see,..... Put the beam in, then jack under it,....So it seems I need to jack up the trusses heels back to level, then install a beam across and under it?
The beam the heel attached to is 2 layers of 2X6. That beam is holding and not sagging. The entire flat roof is level. If the beam is too small I would be seeing deflection in the beam. The span is only about 10' across there.I think your beam is prob to small. who ever built the addition likely did not consult with a structural engineer was the addition permitted and inspected? what is the span, size and, how many ply is the wood beam in the pictures.
the first thing you need to do is get a temporary support under those trusses before they come down.The beam the heel attached to is 2 layers of 2X6. That beam is holding and not sagging. The entire flat roof is level. If the beam is too small I would be seeing deflection in the beam. The span is only about 10' across there.
What could be a problem is the actual connection. These metal brackets are nailed to the truss heels. I see one nail on the side. One of the brackets was had a kink and I was able to see how the bracket was connected to the beam. Again, all I saw was one nail. One nail through the bracket into the beam, then the trusses inserted into the metal bracket and one nail through the bracket into the wood. I counted a total of two nails in one of the connections.
I also think there may have been a load bearing wall across the trusses in that room removed. Unfortunately this city only keeps records for 10 years. Any permits, drawings, inspection records older than 10 years is gone. Not scanned, archived, microfilmed...GONE. Amazing.
There is no way to tell. There is no permit record older than 10 years for ALL properties in this city. Some sort of a paper reduction act or whatever. I have had this happened in another city but they microfilm everything so there is an old archive you can get back to. Did some digging. Original architect is out of business and dead. I did find one neighbor who told me the flat roof section was added later on, in 1970s...by then it was part of the county and not part of the city yet, looked up the county records and the only thing I can find is the tax appraiser's office did noted the added square footage was added 1974 and additional tax imposed...that does not mean it was permitted either but in 1970s most of the hurricane code has not yet been put in place, I don't see any hurricane straps to tie the roof framing to the exterior tie beams. We are concerned about uplifts too.Gone.. or this is an illegal addition and they never pulled a permit.
I am in Miami Florida so no snow.What is the span of the beam you are replacing?
A 2 x 10 wood beam may not be sufficient. Might need a pair of LVL's in there.
*edit*
Reviewed the first picture and just figured you are not in a snow load area. Might be okay.
