This command allows the user to construct an ElasticSection. The inclusion of shear deformations is optional.
| section Elastic $secTag $E $A $Iz <$G $alphaY> |
| section Elastic $secTag $E $A $Iz $Iy $G $J <$alphaY $alphaZ> |
| $secTag | unique section tag |
| $E | Young's Modulus |
| $A | cross-sectional area of section |
| $Iz | second moment of area about the local z-axis |
| $Iy | second moment of area about the local y-axis (required for 3D analysis) |
| $G | Shear Modulus (optional for 2D analysis, required for 3D analysis) |
| $J | torsional moment of inertia of section (required for 3D analysis) |
| $alphaY | shear shape factor along the local y-axis (optional) |
| $alphaZ | shear shape factor along the local z-axis (optional) |
NOTES:
- The elastic section can be used in the nonlinear beam column elements, which is useful in the initial stages of developing a complex model.
