Decomposes beams and shells into their components.

Inputs

ElementElemBeam or shell to disassemble.Element

Outputs

NameIDDescriptionType
ElementElemElementElement
Element identifierElemIdIdentifier of the elementString
Axis of elementAxisLongitudinal axis of beam.Curve
Cross sectionCroSecCross section of the elementCrossSection
JointsJointsJoints at the endpoints of the beam. '-1' means fixed, '0' means free, all other positive values represent the corresponding spring-stiffness. The first six values symbolize the DOFs of the joint at the starting point of the beam, the last six those at the end-point.Integer
MaterialMatMaterial of the elementFemMaterial
Local coordinate systemLCoSysPlane oriented according to the beams local coordinate system.Plane
Element is activeActiveTrue if the element is active.Boolean
BendingBendingTrue if a beam has bending stiffness. Otherwise it is a truss.Boolean
Local eccentricity [cm]Ecce-locPart of beam eccentricity [cm] which is defined in local beam coordinates.Vector
Global eccentricity [cm]Ecce-gloPart of beam eccentricity [cm] which is defined in global coordinates.Vector
Consider BucklingBucklingIf true cross section optimization of the element is done considering buckling. Deactivating buckling can be useful for simulating slender elements which you want to pretension in reality but not in the numerical model.Boolean
Buckling Length Y [m]BklLenYBuckling length [m] of beam in local Y-direction.Number
Buckling Length Z [m]BklLenZBuckling length [m] of beam in local Z-direction.Number
Buckling Length LT [m]BklLenLTBuckling length [m] of beam for lateral torsional buckling.Number
lg [cm]lgDistance of transverse load [cm] from the center of shear of the cross section. Is positive if the load points towards the shear center and acts destabilizing for lateral torsional buckling.Number
NII [kN]NIINormal force [kN] that induces second order effects. Tension is positive, compression negative.Number
X-OrientationX-oriSet X-Orientation of the element: Flips e.g. X-axis of the beam if it points in opposite direction to this vector.Vector
Z-OrientationZ-oriNew orientation of the local Z-axis of the element.Vector
Alpha [deg]AlphaRotation angle about local X-axis [deg] in addition to orientation given by orientation vector.Number
