Both 2-D and 3-D elastic sections are available for response sensitivity computation.

section Elastic $secTag $E $A $Iz <$Iy $G $J>

---

$secTag	unique section object integer tag.
$E	Young’s modulus.
$A	cross section area .
$Iz	second moment of area about the local z-axis .
$Iy	second moment of area about the local y-axis (optional, used for 3-D analysis).
$G	shear modulus (optional, used for 3-D analysis).
$J	torsional moment of inertia of section (optional, used for 3-D analysis).

For 2-D elastic sections, the sensitivity parameters can be: E, A, I.

For 3-D elastic sections, the sensitivity parameters can be: E, A, Iz, Iy, G, J.
