This command is used to construct an elasticBeamColumn element object. The arguments for the construction of an elastic beam-column element depend on the dimension of the problem, ndm:
For a two-dimensional problem:
element elasticBeamColumn $eleTag $iNode $jNode $A $E $Iz $transfTag <-mass $massDens> |
For a three-dimensional problem:
element elasticBeamColumn $eleTag $iNode $jNode $A $E $G $J $Iy $Iz $transfTag <-mass $massDens> |
$eleTag | unique element object tag |
$iNode $jNode | end nodes |
$A | cross-sectional area of element |
$E | Young's Modulus |
$G | Shear Modulus |
$J | torsional moment of inertia of cross section |
$Iz | second moment of area about the local z-axis |
$Iy | second moment of area about the local y-axis |
$transfTag | identifier for previously-defined coordinate-transformation (CrdTransf) object |
$massDens | element mass density (per unit length), from which a lumped-mass matrix is formed (optional, default=0.0) |
NOTE:
The valid queries to an elastic beam-column element when creating an ElementRecorder object are 'force'.
EXAMPLE:
element elasticBeamColumn 1 2 4 5.5 100.0 1e6 9; # elastic element tag 1 between nodes 2 and 4 with area 5.5, E 100 and IZ 1e6 which uses transformation 9
