Purpose: Used to define spring supports in Girder System Projects. (Not applicable to Line Girder Projects.)
--> Given in girder system input
Stiffness of rotational spring supports (k-ft/radian or kN-m/radian) for flexure about a horizontal axis perpendicular to girder "i". Given as a list by reaction beginning at the left bearing. The list is not padded if only one value is given.
