Another design option I've seen is to set another smaller column a few feet away from the crane support frame column (in the direction of the lateral load). The two are laced up with bracing, making a kind of vertical truss. This avoids having to construct a tapered section and spreads out the...

This is a bit dated, however, the 1996 SBCCI "Standard for Hurricane Resistant Residential Construction" gives shear values for 1/2" gyp board used in horizontal diaphragm assemblies: Table 304c2 gives a recommended shear capacity of 70 pounds per linear foot.
This is based on 1/2" thick...
