WebDifferent structural damping ratios of 0.05, 0.10, 0.12 and 0.15 for the massless foundation input model and 0.05 for the viscous-spring boundary model are assumed and compared. The distributions of the damage variable, i.e., stiffness degradation, d, of the dam are shown in Figs 12.11 and 12.12. WebThe factor introduces damping forces caused by the absolute velocities of the model and so simulates the idea of the model moving through a viscous “ether” (a permeating, still fluid, so that any motion of any point in the model causes damping). This damping factor defines mass proportional damping, in the sense that it gives a damping contribution …
