This command is used to construct a ModelasticBeam2d element object. The arguments for the construction of an elastic beam-column element with stiffness modifiers is for 2-D problems
| element ModelasticBeam2d $eleTag $iNode $jNode $A $E $Iz $K11 $K33 $K44 $transfTag |
| $eleTag | unique element object tag |
| $iNode $jNode | end nodes |
| $A | cross-sectional area of element |
| $E | Young's Modulus |
| $Iz | second moment of area about the local z-axis |
| $K11 | stiffness modifier for translation |
| $K33 | stiffness modifier for translation |
| $K44 | stiffness modifier for rotation |
| $transfTag | identifier for previously-defined coordinate-transformation (CrdTransf) object |
NOTE:
The valid queries to an elastic beam-column element when creating an ElementRecorder object are 'force.'
EXAMPLE:
element ModelasticBeam2d 1 2 4 5.5 100.0 1e6 4.0 4.0 2.0 1; # elastic element tag 1 between nodes 2 and 4 with area 5.5, E 100 and IZ 1e6 with K11=K33=4.0, K44=2.0 which uses transformation 1
