Elastic Section
From OpenSeesWiki
Jump to navigationJump to search
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.
