4.5.3. rigidDiaphragm command¶
rigidDiaphragm(perpDirn, rNodeTag, *cNodeTags)¶
Create a multi-point constraint between nodes. These objects will constrain certain degrees-of-freedom at the listed secondary nodes to move as if in a rigid plane with the primary (retained) node. To enforce this constraint,
Transformationconstraint handler is recommended.
direction perpendicular to the rigid plane (i.e. direction 3 corresponds to the 1-2 plane)
integer tag identifying the retained (primary) node
integar tags identifying the constrained (secondary) nodes
