| IfcModulusOfRotationalSubgradeReactionSelect | ADDED |
A measure for modulus of rotational subgrade reaction which expresses the rotational bedding of a structural curve item per length. TRUE denotes infinite stiffness (rigidity). FALSE denotes no stiffness (a release). A numeric value denotes finite linear-elastic stiffness.
