The L 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. This name is used when translating sections through CIMsteel. This property is currently not used.
Group Id
Type the material group identification for the section.
Unit Weight
Type the weight of the section. The unit weight is defined in mass per length pound per foot (lbm/ft).
Area
Type the cross-section area for the section. The area is defined in square inches or square millimeters.
Depth
Type the depth for the section. The depth is defined in inches or millimeters.
Width
Type the breadth for the section. The breadth is defined in inches or millimeters.
Perimeter
The outside perimeter distance for the section.
d
Type the overall depth (longer leg) for the section. The depth is defined in inches or millimeters.
If you are using StructCrossSections-Aust-05.xls data, then d = Depth - tf.
bf
Type the overall width (shorter leg) for the section. The width is defined in inches or millimeters.
tf
Type the flange thickness for the section. The thickness is defined in inches or millimeters.
tw
Type the web thickness for the section. The thickness is defined in inches or millimeters.
kdesign
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
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.
CentroidX
Type the location of the centroid along the local x-axis. The location is defined in inches or millimeters.
CentroidY
Type the location of the centroid along the local y-axis. The location is defined in inches or millimeters.
xp
Type the distance from the designated edge of angle to its plastic neutral axis (PNA) along the local x-axis.
yp
Type the distance from the designated edge of angle to its plastic neutral axis (PNA) along the local y-axis.
Ixx
Type the moment of inertia for the section's local x-axis.
Zxx
Type the plastic section modulus for the section's local x-axis.
Sxx
Type the section modulus for the section's local x-axis.
Rxx
Type the radius of gyration for the section's local x-axis.
Iyy
Type the moment of inertia for the section's local y-axis.
Zyy
Type the plastic section modulus for the section's local y-axis.
Syy
Type the section modulus for the section's local y-axis.
Ryy
Type the radius of gyration for the section's local y-axis.
Rxy
Type the radius of gyration about the local z-axis. The radius is defined in inches or millimeters.
J
Type the torsional moment of inertia for the section.
Cw
Type the warping constant for the section.
ro
Type the polar radius of gyration about the shear center.
H
Type the flexural constant for the section.
lsg

lsg1
Specify the gage distance to the first bolt row on the long side when there are two bolt rows.
lsg2
Specify the gage distance from the first bolt row to the second bolt row on the long side when there are two bolt rows.
ssg
Specify the bolt gage for the short side when there is one bolt row.
ssg1
Specify the gage distance to the first bolt row on the short side when there are two bolt rows.
ssg2
Specify the gage distance from the first bolt row to the second bolt row on the short side when there are two bolt rows.
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
