The BUIUE symbol uses the following properties.
Section Name
Type the section name. 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.
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.
Depth
Type the depth for the section. The depth is defined in meters
Width
Type the width for the section. The width is defined in meters.
Perimeter
The outside perimeter distance for the section.
Top Flange Width
Type the width of the top flange.
Top Flange Thickness
Type the plate thickness of the top flange.
Bottom Flange Width
Type the width of the bottom flange.
Bottom Flange Thickness
Type the plate thickness of the bottom flange.
Web Thickness
Type the thickness of the top flange.
Depth Start
Type the web depth at the start of the member.
Depth End
Type the web depth at the end of the member.
CentroidX
Type the vertical distance from designated member edge to the centroidal axis.
CentroidY
Type the vertical distance from designated member edge to the centroidal 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.
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.
gf
Type the bolt gage for the flange.
gw
Type the bolt gage for the web.
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, whether or not the cross-section is symmetrical about the x-axis depends on dimensional values.
IsSymmetricAlongY
Specify if the cross-section is symmetrical along the local y-axis. For this cross-section, the default value is True.
Symmetries about the x- and y-axes are defined by design properties only. The Flange Width Extension (top and bottom) property is not a design property; therefore, the symmetry calculation
is not affected by this property. This non-affect can cause discrepancies between
the symmetry of the cross-section graphic and the IsSymmetricAlongX and IsSymmetricAlongY properties when non-zero width extensions are defined.
