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& &-cMass&
For a three-dimensional problem:
element elasticBeamColumn $eleTag $iNode $jNode $A $E $G $J $Iy $Iz $transfTag &-mass $massDens& &-cMass&
unique element object tag
$iNode $jNode end nodes
cross-sectional area of element
Young's Modulus
Shear Modulus
torsional moment of inertia of cross section
$Iz second moment of area about the local z-axis
second moment of area about the local y-axis
$transfTag
identifier for previously-defined coordinate-transformation (CrdTransf) object
element mass per unit length (optional, default = 0.0)
to form consistent mass matrix (optional, default = lumped mass matrix)
The valid queries to an elastic beam-column element when creating an ElementRecorder object are 'force'.
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

sp commands
mp commands
block commands
This command is used to construct a linear coordinate transformation (LinearCrdTransf) object, which performs a linear geometric transformation of beam stiffness and resisting force from the basic system to the global-coordinate system.
For a two-dimensional problem:
geomTransf Linear $transfTag &-jntOffset $dXi $dYi $dXj $dYj&
For a three-dimensional problem:
geomTransf Linear $transfTag $vecxzX $vecxzY $vecxzZ &-jntOffset $dXi $dYi $dZi $dXj $dYj $dZj&
$transfTag
integer tag identifying transformation
$vecxzX $vecxzY $vecxzZ
X, Y, and Z components of vecxz, the vector used to define the local x-z plane of the local-coordinate system. The local y-axis is defined by taking the cross product of the vecxz vector and the x-axis.
These components are specified in the global-coordinate system X,Y,Z and define a vector that is in a plane parallel to the x-z plane of the local-coordinate system.
These items need to be specified for the three-dimensional problem.
$dXi $dYi $dZi
joint offset values -- offsets specified with respect to the global coordinate system for element-end node i (the number of arguments depends on the dimensions of the current model). The offset vector is oriented from node i to node j as shown in a figure below. (optional)
$dXj $dYj $dZj
joint offset values -- offsets specified with respect to the global coordinate system for element-end node j (the number of arguments depends on the dimensions of the current model). The offset vector is oriented from node j to node i as shown in a figure below. (optional)
A refresher on Euclidean Geometry and Coordinate Systems:
A single vector may be defined by two points. It has length, direction, and location in
space. When this vector is used to define a coordinate axis, only its direction is important. Now any 2 vectors, Vr and Vs, not parallel, define a plane that is parallel to them both. The cross-product of these vectors define a third vector, Vt, that is perpendicular to both Vr and Vs and hence normal to the plane: Vt = Vr X Vs.
The element coordinate system is specified as follows:
The x-axis is a vector given by t The vector vecxz is a vector the user specifies that must not be parallel to the x-axis. The x-axis along with the vecxz Vector define the xz plane. The local y-axis is defined by taking the cross product of the x-axis vector and the vecxz vector (Vy = Vxz X Vx). The local z-axis is then found simply by taking the cross product of the y-axis and x-axis vectors (Vz = Vx X Vy). The section is attached to the element such that the y-z coordinate system used to specify the section corresponds to the y-z axes of the element.
NOTE: When in 2D, local x and y axes are in the X-Y plane, where X and Y are global axes. Local x axis is the axis connecting the two element nodes, and local y and z axes follow the right-hand rule (e.g., if the element is aligned with the positive Y axis, the local y axis is aligned with the negative X axis, and if the element is aligned with the positive X axis, the local y axis is aligned with the positive Y axis). Orientation of local y and z axes is important for definition of the fiber section.
Element 1&: tag 1&: vecxZ = zaxis
geomTransf Linear 1 0 0 -1
Element 2&: tag 2&: vecxZ = y axis
geomTransf Linear 2 0 1 0
If there was a rigid offset at the top of element 1:
geomTransf Linear 1 0 0 -1 -jntOffset 0.0 0.0 0.0 0.0 -$Offset 0.0
