Brick Veneer Height Limitations

[crk]

If the height of brick veneer supported by wood framing is 40'-0" and 51'-0", What can be done so that it will be safe in compression failure, slenderness failure and out of plane failure.

Check your delfection limits. 51'-0 seems awfully high to be supported by wood. You may want to put in some relieving angles.

Check technical note @

They have notes on breek veneer with wood framing.

In most codes, it is not allowed to vertically support masonry or concrete with wood. See Uniform Building Code 97 Section 2307.

Or check the new IBC 2000, Sections 2304.12 and 2305.1.5.

If the brick is supported by concrete foundations and the wood is only laterally supporting the masonry, then you need to keep the lateral deflection less than L/600 in wall studs. The brick will then support its own weight and there will be little, if any, flexural stresses in the brick due to lateral forces.

You simply need to check the axial stress in the brick. This is dealt with by the Brick Institute Specifications.

You should also account through details to allow for the vertical expansion in the brick. The coefficient of thermal expansion for brick masonry is .00034 F (.00061 C) This gives quite a bit of expansion at 100 degrees F. If you restrain the top, there will be a large amount of stress induced from thermal forces
