4.16.1. Elastic Section¶
-
section
('Elastic', secTag, E_mod, A, Iz, G_mod=None, alphaY=None)
-
section
('Elastic', secTag, E_mod, A, Iz, Iy, G_mod, Jxx, alphaY=None, alphaZ=None) This command allows the user to construct an ElasticSection. The inclusion of shear deformations is optional. The dofs for 2D elastic section are
[P, Mz]
, for 3D are[P,Mz,My,T]
.secTag
(int)unique section tag E_mod
(float)Young’s Modulus A
(float)cross-sectional area of section Iz
(float)second moment of area about the local z-axis Iy
(float)second moment of area about the local y-axis (required for 3D analysis) G_mod
(float)Shear Modulus (optional for 2D analysis, required for 3D analysis) Jxx
(float)torsional moment of inertia of section (required for 3D analysis) alphaY
(float)shear shape factor along the local y-axis (optional) alphaZ
(float)shear shape factor along the local z-axis (optional)
Note
The elastic section can be used in the nonlinear beam column elements, which is useful in the initial stages of developing a complex model.
