"Webdamping ratio (ξ) the greater is the difference between the complete and steady-state maximum responses. For instance, in case of ξ=0, with a value of β=0.7, the complete magnification factor is 3.32 while the steady-state magnification factor is 1.96. In this case the steady-state magnification factor represents only 60% of the complete maximum " - Dynamic magnification ratio
