***No Framing Situation Required***

Stitch Plates for a Vertical Brace with Plain Ends
Section size: An angle section.
Input connection type: ' Plain End '.
Settings: " Double material " in a ' Star ' configuration. To get three equally spaced spacers, you can set the " Max stitch plate spacing " or the " Number of stitch plates ." You can also get stitch plates on ' Back to back ' angles or channels.

Here's an example of a double channel with stitch plates. Both ends of this channel are set to ' Plain End '. The member is displayed in solid transparent main so that you can see the bolted rectangular stitch plates.

***Various Framing Situations***

Rod Bracing
Connection Design Locks = " Brace Connection To Gusset "
Vertical brace section size: round bar
Framing situations: Brace to beam or brace to column or brace to column and base/cap plate or brace to beam & column or 2-point or 3-point braces with shared gusset.
Setup: " Tension Only Braces " in Member Detailing and Fabricator Options provides various setup options. The " Capacity " (nominal strength) of a clevis and turnbuckle is stored in the local shape file. Fu and Fy values at Home > Project Settings > Job > Turnbuckle / Clevis / Pin Grades are used by connection design.

Example 1: A rod brace in a beam & column framing situation, with the beam framed to a column web. " UFM special case design " is set to ' No special case ' under " Connection specifications " on the Vertical Brace Edit window.

Example 2: Same as example 1, except that " UFM special case design " is set to ' Special case 3 '. Also of relevance to this situation is the setup option " Design for a beam-column gusset if flange end distance is less than " in Plate Design Settings .

Another example of back-to-back double-angle vertical bracing. Both of these braces go to the same point on the beam workline. If that point was below the work line, the connection would still be designed, but the left brace would be lower. " Brace to supporting member " and " Brace to brace " field clearances apply to this connection.

Vertical Braces with a Shared Gusset
Connection Design Locks = " Gusset 2 Point " " Weld Conn2 " " Brace Connection To Gusset HSS Welded "
Section size: ' HSS rectangular ' (shown) or ' HSS round ' or ' angle ' or ' channel ' or ' tee ' or ' wide flange '.
Comments: The braces must be closer together than a setup value .

Another example of 2-point vertical bracing. This example shows wide flange vertical braces with webs vertical.

Another example of 2-point vertical bracing. This example shows stem-vertical tee braces with web connection plates.

Seismic 2--point gusset plates can be designed. when " Seismic brace " is set to ' Yes '. In this example, " AISC seismic 1st ed. 2pt gussets " is not checked, resulting in a 2nd edition seismic 2-point gusset. Specifying a 2-point gusset with a clip angle gets you the failure message " Gusset to supporting clip angle connection not allowed for seismic ."

Stiffeners can be added to 1st edition 2-point seismic gusset plates. You get 1st edition design when " AISC seismic 1st ed. 2pt gussets " is checked. The stiffeners are user added using locks that are available in the " Gusset 2 Point " leaf.

VIDEO

When settings are changed on one vertical brace on a 2-point gusset, both braces fail. When the settings are then changed on the other vertical brace to match the first vertical brace, the AISC seismic 1st edition 2pt gusset is properly designed.

VIDEO Before v2017, SDS2 connection design required that the middle brace of 3-point vertical bracing needed to be perpendicular to the supporting member to which the shared gusset plate attached. In this video, the middle 3-point brace to the horizontal beam is perpendicular, while the middle 3-point brace to the sloping beam is not perpendicular to that beam.

Another example of 3-point vertical bracing. The section sizes and framing situations that apply to 3-point vertical bracing is described above . In this example, the three braces are wide flange braces with paddle plates, which are discussed above . Notice that this example shows three vertical braces framing to a column. The example above shows vertical braces framing to a beam. In both examples, the center brace is perpendicular to the supporting member.
