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, Jxx, Iy, Iz, Avy, Avz, transfTag, <'-mass', massDens>, <'-cMass'>)
For a three-dimensional problem:
eleTag
(int)unique element object tag
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)
