Wood Supporting Masonry or concrete?
Wood Supporting Masonry or concrete?
(OP)
Section 2304.12(IBC 2000) and Section 2307(UBC 1997) says: "Wood members shall not be used to permanently support the dead load of any masonry or concrete."
Situation: 3" concrete floor slab.
What is the reason the building code has precluded wood walls as supports and not allowed the engineer to use engineering judgement? (Possibility is creep or rot but couldn't this be accounted for in the design?)

To prevent the concrete from contacting the wood bearing wall a piece of felt could be placed to act as a barrier. The way the code reads however, it seems as if wood walls are barred completely from any load transfer in regards to concrete. (This pertains to structural concrete, also depends on the definition of structural)
Wood bearing is allowed in residential construction in the IBC but not sure in the UBC.

Now you've got me confused....I've argued many times with my architects that no way shape or form can brick veneer be supported by wood members. UBC 97, section 2307 states:
"Wood members shall not be used to permanently support the dead load of any masonry or concrete".
Then the exception:
"Veneer of brick, concrete or stone applied as specified in Section 1403.6.2 may be supported by approved, treated wood foundations when the maximum height of veneer does not exceed 30 feet above the foundations. ....
So veneer can be supported by a treated wood foundation, but not by a steel angle bolted to wood framing. That's how I interpret it. Now I would probably agree with you that the "problem" is with cementitious materials weeping moisture into the wood...but the code doesn't allow it.

IBC 2000 (Section 1405.5) allows this application provided the masonry does not exceed 40 psf and that the angle is attached to the wood studs with lag bolts.
