I can't pretend I'm an engineer or anything, but the urge to come up with cute names for things was irresistable, so I spent a few minutes
doing a little research.
Your toolset is aimed at letting people prepare their architectural designs for a Quake, so how about "Strand" or "Tendon"?
I tried working in some reference to Tuned Mass Dampers at first, mainly because I like the phrase, but nothing catchy or meaningful was forthcoming. Maybe somebody else can run with that.
