This command is used to construct an ElasticSection object.
section Elastic $secTag $E $A $Iz <$Iy $G $J>
$secTag |
unique section object 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 (optional, used for 3D analysis) |
$G |
Shear Modulus (optional, used for 3D analysis) |
$J |
torsional moment of inertia of section (optional, used for 3D analysis) |
This command is useful for patch tests of the nonlinear beam-column elements. It also allows nonlinear beam-column elements to be used for elastic analysis.
EXAMPLE:
section Elastic 1 29000 100 100000 80000 20000 100000; # create elastic section with IDtag 1
