Double angle
section
property-spec = D WF TF SP IZ IY IX CY AY AZ RVV
- D
- Depth of angle (i.e., length of the leg along the
local y-axis)
- WF
- Width of angle (i.e., length of the leg along the
local z-axis)
- TF
- Thickness of angle leg
- SP
- Space between angles.
- IZ
- Moment of inertia about local z-axis (usually strong
axis)
- IY
- Moment of inertia about local y-axis
- IX
- Torsional constant
- CY
- Distance from the face of angles to the center of
gravity (C.G.) along the local y-axis.
- AY
- Shear area in local y-axis. If zero, shear
deformation is ignored in the analysis.
- AZ
- Shear area in local z-axis. If zero, shear
deformation is ignored in the analysis.
- RVV
- The radius of gyration about the minor principal axis for single
angles - z-z axis for
TA ST angles, and y-y axis for
TA RA angles.
