I'm doing FEA on a small pressure vessel. It's a nonstructural component listed in Table 13.6-1. In the FEA, I would like to fix the mounting lugs and apply the seismic acceleration to the vessel to get its results. As is, I don't see how to apply the F_p force from Eqn. 13.3-1. It's unclear where that force would be applied to the vessel.
Slide 16 of your PDF insinuates that 0.4*S_DS*(1 + 2*z/h) is the acceleration. Could I shift the other terms to the opposite side to get the acceleration this way?
