TR.19.4 Double Angle

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.
