Viscous Damping 2
Viscous Damping 2 : Natural Disaster. The most commonly used type of damping for analytical or numerical studies of earthquake response of a structure. A viscous damper generates a force proportional to the relative velocity of its two attachment points in a direction that opposes the motion. Viscous damping is one of the few forms of damping that can be described by linear equations. See Jennings (2003)
