| 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.
