Is there a way to input pile (node) stiffness and damping in Staad for a time history analysis?That means inputting support stiffness and damping values for all 6 degrees of freedom (translation and rotation)
You can assign Fixed But support with the required spring stiffness in each DOF. In the Time Hitsory definition, select the CDAMP (composite damping) option.

The CDAMP option specified on the website is only for three translational direction and not the 3 rotational direction

Can you please share an example of format/file for how to use CDAMP?
