Used to define unique damping ratios for the individual modes used in a dynamic analysis. It is used in response spectrum and time history analysis.
|Evaluate|| This option is to instruct
STAAD.Pro to calculate the damping
ratio for each mode based on the frequency of the mode and the
Maximum values entered in the respective
The formula used to evaluate the damping ratio is explained in Evaluate Damping.
|Explicit|| Provide values of damping ratio for the
corresponding mode number.
Refer to Explicit Damping for additional details.
