4.2.3.3. Elastic Timoshenko Beam Column Element

This command is used to construct an ElasticTimoshenkoBeam element object. A Timoshenko beam is a frame member that accounts for shear deformations. The arguments for the construction of an elastic Timoshenko beam element depend on the dimension of the problem, ndm:

element('ElasticTimoshenkoBeam', eleTag, *eleNodes, E_mod, G_mod, Area, Iz, Avy, transfTag, <'-mass', massDens>, <'-cMass'>)

For a two-dimensional problem:

element('ElasticTimoshenkoBeam', eleTag, *eleNodes, E_mod, G_mod, Area, Iz, Jxx, Iy, Iz, Avy, Avz, transfTag, <'-mass', massDens>, <'-cMass'>)

For a three-dimensional problem:

eleTag (int)	unique element object tag
eleNodes (list (int))	a list of two element nodes
E_mod (float)	Young’s Modulus
G_mod (float)	Shear Modulus
Area (float)	cross-sectional area of element
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
Avy (float)	Shear area for the local y-axis
Avz (float)	Shear area for the local z-axis
transfTag (int)	identifier for previously-defined coordinate-transformation (CrdTransf) object
massDens (float)	element mass per unit length (optional, default = 0.0)
'-cMass' (str)	to form consistent mass matrix (optional, default = lumped mass matrix)
