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
`eleNodes` (list (int))	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)
