The HSSRs cross section symbol defines rectangular, hollow, structural sections with a seam indicator 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-section area for the section. The area is defined in square inches and square millimeters.
Depth
Type the overall depth of the section.
Width
Type the width for the section. The width is defined in inches or millimeters.
Perimeter
The outside perimeter distance for the section.
tnom
Type the nominal wall thickness of the section.
tdes
Type the design wall thickness of the section.
b_t
Type the width to thickness ratio of the section.
h_t
Type the height to thickness ratio of the section.
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.
IsHollow
Specify if the cross-section is hollow or not. For this cross-section, the default value is True (1).
IsSymmetricAlongX
Specify if the cross-section is symmetrical along the local x-axis. For this cross-section, the default value is True (1).
IsSymmetricAlongY
Specify if the cross-section is symmetrical along the local y-axis. For this cross-section, the default value is True (1).
Has Seam
Specify if the cross-section has a seam indicator or not. For this cross-section, the default value is True (1).
Seam Angle
Specifies the location of the seam. This angle is measured clockwise from orientation vector of the member looking down the member from the start end.
