Mirror

Specify whether the truss is mirrored. If you select this option, the software places up to half of the truss and then mirrors that portion to complete placement. This option is not available if you type an even number in the No. of Posts box on the General tab.

The following options are available for both Horizontal Bracing (on the horizontal planes of the truss) and Vertical Bracing (on the vertical planes of the truss):

Bracing Type

Specify the type of bracing to place between each pair of stringers (horizontal bracing) or girders (vertical bracing). Select Cross to place two braces in an X configuration. Select Chevron to place one diagonal brace with each brace going end-to-end along the truss to form V-shapes. Select N-Type to place one diagonal brace with each brace forming an N-shape along the truss.

Member Type

Select the type of cross bracing member that you want to place, such as a brace or vertical brace.

Preview

Displays an image with the bracing member locations. The image displays in a separate window.

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 bracing members. 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 for the section to use. Sections are defined in the reference data.

Material

Select the material for the bracing member.

Grade

Select the material grade for the bracing member.

Cardinal Point

Specify the relative position of the structural section to the cross bracing 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 horizontal and vertical bracing member of the truss.

Angle

Specify the orientation of the end frame member cross-section. A value is defined for each horizontal and vertical bracing member of the truss.
