# Section Aggregator for Sensitivity
|
unique section object integer tag. |
$matTag1, $matTag2 … |
previously-defined UniaxialMaterial Objects. |
$string1, $string2 … |
force-deformation relations corresponding to each section object. One of the following strings can be used. |
P |
axial force-deformation. |
Mz |
moment-curvature about section local z axis. |
Vy |
shear force-deformation along section local y-axis. |
My |
moment-curvature about section local y axis. |
Vz |
shear force-deformation along section local z-axis. |
T |
torsion force-deformation. |
|
second moment of area about the local y-axis (optional, used for 3-D analysis). |
<-section $sectionTag> |
specifies a previously defined Section object (identified by the argument $sectionTag) to which these UniaxialMaterial objects are added to define a new Section object. |
