Yours could be an interesting structural problem, especially 
if the capacitors are rated for pulse discharge service. The 
typical Lorentz force reactions (attractive and repulsive) on 
pulse-discharge capacitors and their busbars during a discharge 
could produce sharp impulse loads well in excess of 10 tons.
I have witnessed a busbar support failure where three 5/16 GR8
bolts failed in tension.

Usually these forces are resolved within the capacitor framework;
however if bushings supporting the high-current busbars are 
mounted directly to the foundation instead of the capacitor frame, 
significant concentrated stresses could develop where the support 
bushings meet the foundation.
