Specifies all truss structural members except end frames.
Stringers
A truss has four stringers:
Member Type
Select the type of member that you want to place, such as Stringer, Beam, Joist, Girder, or Column.
Standard
Displays the corresponding steel design standard. This value is defined in the catalog and is read-only.
Section
Define the cross-section for the member. If you know the section name that you want, type it in. Use the asterisk [*] character wild card to see all sections containing that text. For example, type W10X* to see all W10X sections in the catalog. Select More to browse the catalog.
Material
Select the material type for the structural member.
Grade
Select the material grade for the structural member.
Preview
Displays an image with the stringer locations. The image displays in a separate window.
Cardinal Point
Specify the relative position of the structural section to the member placement line. Fifteen cardinal positions are available. The location of cardinal points 10 (center-of- gravity) and 15 (shear center) depend on the section shape. The local z-axis of the member and the center-of-gravity point of the section define cardinal points 11 and 14. The local y-axis of the member and the center-of-gravity point of the section define cardinal points 12 and 13. A value is defined for each stringer of the truss, Stringer1, Stringer2, Stringer3, and Stringer4.
Angle
Specify the orientation of the stringer cross-section. A value is defined for each stringer of the truss, Stringer1, Stringer2, Stringer3, and Stringer4.
Walkway Support
A truss typically has multiple walkway supports:
Member Type
Select the type of member that you want to place, such as Support, Landing, Stair Attachment, Rung, or Rail.
Standard
Displays the corresponding steel design standard. This value is defined in the catalog and is read-only.

Angle
Specify the orientation of the support cross-section.
