Resistance and Inertia: How Foundation Size Affects Seismic Movement

[fanieh]

If an object is heavier.. it has more resistance to inertia..

during seismic movement.. when the ground shakes or accelerates.. does it mean bigger foundation would be more resistant and move less.. and smaller foundation can move more?

here's a good article on mass and inertia
