joist higher then my Sill Plate

LP Question

I was told since moisture is in the joist, it will shrink over time, but I am ready to put on my T&G and there is a gap between the floor and sill, How do I deal with that issue?

A longer description of your problem is needed---pictures will get you an accurate answer.

How much of a gap?
If the joist shrink so will the rim joist.

you need to shim the joist to the sill plate and make sure the tops of the joists line up with the top of the band.

Sounds like the joists are hung off sill and tops are slightly above the plane of the mud sill, which is good. (No rim joist on mud sill). Around here, 1/8" to 5/16" is normal, depending on the lumber size and location, chart on pp.51; http://books.google.com/books?id=iwS...rafter&f=false

Be sure to run the ply deck over the sill for floor shear flow in a diaphragm application (not as pictured in other link, following page), follow 3.6 for shear blocking with running joists on page 17 for minimum 90mph wind zone. Check locally or follow engineered plans exactly; http://www.awc.org/pdf/WFCM_90-B-Guide.pdf
