Re: Eienbaum Garage Forming
Dear Mr. Eicnbsam,
Far your request, we have inspected the existing garage roof flaming to determine how to be properly support roof
and ceiling loads.
The existing framing consists of a 2x12 ridge board, 2x6 raftm at 16" on center, 2xd collar ties at top of ratters, 2x8
ceilingjohns at 16" on center supported by (2)12" LVL beam at mid- span. The ridge board is spliced at mid span,
where some sagging began to appear. Four post: along the length of the ridge board were installed to transfer the
load unto the LVL beam below. Given this beam's 32 foot clear span and 12" depth, significant deflection was
observed in the LVL beam as well.
To resolve this issue, we advise that the ridge board bejacked up to its original placement and a 2 foot long 2x6 be
nailed on each side of the spliced board, as shown in the enclosed detail. This should help prevent the splice from
spreading spar[ and sagging. In addition, strengthen the LVL beam by installing (2)16" LVL on top of the existing
beam end nailing Simpson LSTAl2 (or equiv.) straps on each side at 24" on center. Replace the post supporting the
ridge board at the spliced section.
Install Simpson LSTA24 (or equiv.) shape to the underside of every cailingjoist at the LVL beam to al low roof
framing to at as simple trusses. See the enclosed typical truss detail.
Please advise if may additional information is needed.
