The ST 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.

Depth

Type the depth for the section. The depth is defined in inches.

Width

Type the flange width for the section. The width is defined in inches.

Perimeter

The outside perimeter distance for the section.

d

Type the depth for the section.

bf

Type the width for the section.

tw

Type the web thickness for the section. The thickness is defined in inches.

tf

Type the flange thickness for the section. The thickness is defined in inches.

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.

CentroidY

Type the distance to the centroid along the local y-axis. This distance is defined in inches or millimeters.

yp

Type the distance from the designated edge of angle to its plastic neutral axis 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.

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, 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.
