Basically I'd run LVL support perpindicular to the 2x's at the mid point
That I think is what Gary said also
So determine where that would be on each wall & let us know (pics) if there is anything on either wall that would prevent that

Those pictures are scary! I would remove the plywood and any load from above, right away. One AC wire is being pinch from the plywood above. The garage car door back-hang track is loading 50-100# on the individual ceiling joist it is hung from. I'm surprised it hasn't failed yet. To add #1 sisters next to each would require jacking the old (nearly impossible) joists and sistering. Easier would be the beam below, lifting 3/4 at a time (86#), alone . Lift one end onto a sawhorse, then ladder, then beam pocket, other end similar but onto movable double trimmer studs. OR, you could build your own beam with 2x4's and plywood, 25', 60# per ft.load, weighs 6# per foot: called "Nailed Structural Use Panel & lumber beams- Z-416, free pdf: http://www.apawood.org/level_c.cfm?c...ub_ply_libmain

Be safe, Gary

beam support


Curious. What are you folks recommending he do for supporting the ends of this new beam? Sooner or later, it sounds like someone needs to address what is holding the beam up, and what is holding up what is holding the beam; posts and foundation below them. Or, did I miss something?

Whoops! My first two posts I said check with your B.D., forgot on this one, sorry.
He hasn't decided to sister or not, beam or not, or home-made trusses, with the approval of the Inspector for the correct wood rating, fasteners, loads, etc.: http://docs.google.com/viewer?a=v&q=...6fTirapfPwoKzA
I though we were in the idea mode, discussing options before posts, footings, sistering bolting, lateral rotation (blocking), etc., good point to keep in mind for later, though.

Be safe, Gary

Replace or sister saging garage joists


Dear Bill, a 25 foot span requires a minimum of 2 x 10 x X to support the structural load. Moreover, you didn't mention what the pattern is above the 2x6 that helps (forms a W" like pattern), note this helps support point load across the roof span. You will need to use bolts thru the wood to sister the joists, using nails or screws is usually not allowed in most build codes, plus don't forget the Simpson's fastners to tie into blocking at ends and where you connect to roof joists, you may use construction adhesive between exist and new joists. In addition, you will definitely want to check with a structural engineer and you're local building department on what should be the "minimum" you're going to need to do.
If it was me, I'd double check to see cost differences between LVL and no.1 structural grade wood to use. A structural engineer will be able to help tremendously on what is required and will certify install and products used.
Presently, I'm going to similar fashion but I have to sister in to existing 2x4x22 that were used in the 1920's, with no webbing support above, so I'm adding in the two by tens and 2x8 for webbing pick up the load differential across the spanin my case of only 22 feet. My problem, and you might have a similar one, is trying to get 22 feet or your case 24 or 25 feet of board into and resting the required 6" beyond walls... it's not the easiest thing to do, and I may need to cut out the rafters to get the right joists into place and then double up joists prior to putting them back.
I hope this helps, good luck
