The 2L cross section symbol defines double-angle sections and 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-sectional area for the section. The area is defined in square inches or square millimeters.
Depth
Type the depth for the section (longer legs). The depth is defined in inches or millimeters.
d
Type the depth for the section (shorter legs). The depth is defined in inches or millimeters.
bf
Type the width of a single angle. The width is defined in inches or millimeters.
Width
Type the width of the entire section. The width is defined in inches or millimeters.
Perimeter
Type the outside perimeter of the section.
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 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 outer face of the flange to the web toe of the fillet of the rolled shape or the equivalent distance on welded section.
bb
Type the back-to-back spacing on the section.
CentroidY
Type the centroid location along the y-axis. The location is defined in inches or millimeters.
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.
Ryy
Type the radius of gyration for the section's local y-axis.
ro
Type the polar radius of gyration about the shear center.
H
Type the flexural constant.
bb Configuration
Specifies which legs of the angles are placed back-to-back. Type 0 for equal leg angle. Type 1 to place the long legs back-to-back. Type 2 to place the short legs back-to-back.
lsg
Specify the bolt gage for the long side when there is one bolt row. See Member Cross Sections.
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 between the first and second bolt rows 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
Specify if the cross-section is symmetrical along the local y-axis. For this cross-section, the default value is True.
