Description

In Part I we analyzed how ground movement can cause vibrations in a building. Sometimes these resulting vibrations can end up being too big, resulting in discomfort of the people occupying the building or, in the worst case scenario, the building collapsing.

The process by which free vibrations diminish is called damping. Energy of the vibrating system is released by various mechanisms (usually several at once). In a vibrating building, friction at connections and the formation of microcracks are just two possible ways energy is dissipated. It is extremely difficult (and at times impossible) to describe each mechanism individually.
