However, for the very pliant systems such as base isolated structures, with a relatively low bearing stiffness but with a high damping, the so-called "damping force" may turn out the main pushing force at a strong earthquake. This finding created a theoretical ground in earthquake engineering for a damping-disengaged base isolation technology called Earthquake protector.
