# Uniaxial Section

This command is used to construct a UniaxialSection object which uses a previously-defined UniaxialMaterial object to represent a single section force-deformation response quantity.

```tcl section Uniaxial $secTag $matTag $quantity ```

secTag

unique section tag

matTag

tag of uniaxial material

quantity

the force-deformation quantity to be modeled by this section object. One of the following strings is 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 z-axis

Vz Shear force-deformation along section local z-axis

T Torsion Force-Deformation
