minimum footing requirements for shear wall?
minimum footing requirements for shear wall?
(OP)
I did calcs for a long building which required existing hallways to be upgraded to 1-hour fire resistance.
Since these walls were being re-paneled anyway, I used the shear resistance to qualify the resisting capacity of the building.
The walls sit on a 4" slab.
The entire slab is surrounded by a 12" below grade perimeter footing. So, I can qualify the bearing beneath the slab as 1500 PSF, and the walls have only 100 PLF.
Does anyone foresee problems at review? It was submitted today.

I assume with a long wall that holddowns were not needed and that if seismic governed for the gyp that you used half sgtresses for the shearwall capacity?

That is a good mention. I thought of it in process, then forgot it.
Using IBC 2006 Table 1911.2, I can spec .25" dia. bolts @ 4' o.c. (500# shear allow). The embed is only 2.5", leaving 1.5" clear.
Plus there is a vapor barrier.
