4.2.3.1. Elastic Beam Column Element¶
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)
- element('elasticBeamColumn', eleTag, *eleNodes, Area, E_mod, Iz, transfTag, <'-mass', mass>, <'-cMass'>, <'-release', releaseCode>)
- element('elasticBeamColumn', eleTag, *eleNodes, secTag, transfTag, <'-mass', mass>, <'-cMass'>, <'-release', releaseCode>)
For a two-dimensional problem
- element('elasticBeamColumn', eleTag, *eleNodes, Area, E_mod, G_mod, Jxx, Iy, Iz, transfTag, <'-mass', mass>, <'-cMass'>)
- element('elasticBeamColumn', eleTag, *eleNodes, secTag, transfTag, <'-mass', mass>, <'-cMass'> <'-releasez', releaseCode>, <'-releasey', releaseCode>)
For a three-dimensional problem
eleTag
(int)unique element object tag
a list of two element nodes
Area
(float)cross-sectional area of element
E_mod
(float)Young’s Modulus
G_mod
(float)Shear Modulus
Jxx
(float)torsional moment of inertia of cross section
Iy
(float)second moment of area about the local y-axis
Iz
(float)second moment of area about the local z-axis
secTag
(int)identifier for previously-defined section object
transfTag
(int)identifier for previously-defined coordinate-transformation (CrdTransf) object
mass
(float)element mass per unit length (optional, default = 0.0)
'-cMass'
(str)to form consistent mass matrix (optional, default = lumped mass matrix)
'releaseCode'
(int)moment release (optional, 0=no release (default), 1=release at I, 2=release at J, 3=release at I and J)
