From Machaca's post:
The external aerodynamic and mass inertial loadings on the vertical stabilizer can also be quantified as a net shear (a side load), a net bending (a moment about the longitudinal axis), and a net torsion (a moment about the vertical axis), as shown in figure 9.
Referring to another of your recent posts, I wonder if you noticed that the A300 also has an "arm 36 g"? The NTSB calls it a "support strut" and there's no mention of any damage to it. From NTSB report on AA587:
The rudder is attached to the vertical stabilizer rear spar by seven hinge arm assemblies. (...) The rudder is also attached to the vertical stabilizer rear spar by a support strut assembly, which maintains vertical alignment of the rudder. This assembly consists of a support strut and a support strut attachment fitting on the vertical stabilizer skin panels and rear spar. The support strut and its attachment fitting are made of an aluminum alloy. The support strut assembly is installed above and attached to hinge arm assembly number 4.
