The HSSC cross section symbol defines circular, hollow structural sections and uses the following properties. The HSSC symbol is also used for Pipe cross-sections.

Section Name

Type the section name. This name appears when labeling 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 of the section.

Width

Type the width of the section.

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.

D_t

Type the ratio of the diameter to the thickness.

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.

IsSymmetricAlongX

Specify if the cross-section is symmetrical along the local x-axis. For this cross-section, the default value is True.

IsSymmetricAlongY

Specify if the cross-section is symmetrical along the local y-axis. For this cross-section, the default value is True.
