The WT cross section symbol uses the following properties.
Section Name
Type the section name. This name appears when you label members. The section name must be unique within the section standard.
Short Name
Type the short name for the section.
EDI Name
Type the Electronic Data Interchange name for the section.
Group Id
Type the material group identification for the section.
Unit Weight
Type the nominal weight of the section. The unit weight is defined in mass per length, pound per foot (lbm/ft).
Area
Type the cross-sectional area for the section. The area is defined in square inches or square millimeters.
Depth
Type the overall depth for the member (longer legs for angles). The depth is defined in inches or millimeters.
Width
Type the flange width. The width is defined in inches or millimeters.
Perimeter
Type the outside perimeter distance of the shape.
d
Type the overall depth of the section (longer legs for angles). The depth is defined in inches or millimeters.
bf
Type the flange width. The width is defined in inches or millimeters.
tw
Type the web thickness. The thickness is defined in inches or millimeters.
tf
Type the flange thickness. The thickness is defined in inches or millimeters.
kdesign
(for design) Type the distance from the outer face of the flange to the web toe of the fillet of the rolled shape or the equivalent distance on the welded section.
kdetail
(for detail) Type the distance from the outer face of the flange to the web toe of the fillet of the rolled shape or the equivalent distance on welded section.
Ixx
Type the moment of inertia about the x-axis.
Zxx
Type the plastic section modulus about the x-axis.
Sxx
Type the elastic section modulus about the x-axis.
Rxx
Type the radius of gyration about the x-axis.
Iyy
Type the moment of inertia about the y-axis.
Zyy
Type the plastic section modulus about the y-axis.
Syy
Type the elastic section modulus about the y-axis.
Ryy
Type the radius of gyration about the y-axis.
J
Type the torsional moment of inertia.
Cw
Type the warping constant.
CentroidY
Type the centroid Y dimension.
yp
Type the vertical distance from the designated member edge to the plastic neutral axis.
ro
Type the polar radius of gyration about the shear center.
H
Type the flexural constant.
IsHollow
Specify if the cross-section is hollow or not. For this cross-section, the default value is False.
IsSymmetricAlongX
Specify if the cross-section is symmetrical along the local x-axis. For this cross-section, the default value is False.
IsSymmetricAlongY
Specify if the cross-section is symmetrical along the local y-axis. For this cross-section, the default value is True.
