Before engineering the trusses, few connections need to be manually defined in order to transfer loads
Connections between trusses, jack trusses perpendicular to girder truss meet girder
Connection between panels, and panel to truss.
Hip slope/panel must be supported by an end wall / beam
Check member material, selected grade is used in engineering
Use joist hangers or direct screw connection between trusses to generate support relation between girder truss and trusses supported by girder. Connections must be correctly defined between truss/panel members.
Add Connection
In ‘Modeling tab’ click on Joint icon → Connection Details
TIP
When working on a building model or drawing, you can pin multiple browsers on the screen to speedup the design/detailing
You can open a new browser from your opened browser by pressing button.
To activate this button you need to open one browser and pin that first anywhere on the screen by pressing this button. Then when you opened another browser form the ribbon bar. button on the first pinned browser get activated.
You can also hide pinned /opened browser/s. In View tab → List → Hide Browsers
Truss to truss 'Direct screw connection'
In the Select dialog box, select Trusses folder and click the ‘Direct screw connection’
Pay attention to the instructions at the bottom left corner of Vertex window
Pick a window around the ends of the trusses to be connected and the girder truss, Right click and confirm.
In 'Direct Screw Joint' dialog box', accept the defaults and click on OK.
Trusses will have direct screw connection to the girder truss as shown
Truss to wall 'Direct screw connection to wall'
In the Select dialog box, select Trusses folder and click the ‘Direct screw connection to wall’
Pay attention to the instructions at the bottom left corner of Vertex window
Select the truss/s, right click and click on OK to confirm
Select the wall, right click and click on OK to confirm
In 'Direct Screw Joint' dialog box, accept the defaults and click on OK.
Truss will have a screw connection to the walls
Panel to truss multiple direct screw connection
In ‘Modeling tab’ click on Joint icon → Connection Details
In the Select dialog box, select Panels folder and click the ‘Panel to truss multiple direct screw'
Pay attention to the instructions at the bottom left corner of Vertex window as shown.
Select the panel, ( that need to be connected to the truss ) right click and click on OK to confirm
Select the truss ( the panel need to connected to ), right click and click on OK to confirm
In 'Direct Screw Connection' dialog box, accept the defaults and click on OK.
Panel to truss multiple direct screw connection have been added
Follow similar process to add rest of the panel to truss connections.
Panel to Panel or 'Panels multiple direct screw' connection
In ‘Modeling tab’click on Joint icon → Connection Details
In the 'Select' dialog box, select 'Panels' folder and click on ‘Panels multiple direct screw'
Again pay attention to the instructions at the bottom left corner of Vertex window
Select the panels that need to be connected to each other, right click and click on OK to confirm
In 'Direct Screw Connection' dialog box, accept the defaults and click on OK.
Panel to panel multiple direct screw connection have been added.
Follow similar process to add rest of the panel to panel connections.
TIP
Connection tie can also be used in some cases to connect jack truss to corner jack truss, or hip panel rafter to truss etc.
In ‘Modeling tab’ click on Joint icon → Connection Details
In the Select dialog box, select Joist and rafter folder and click the ‘Connection tie'.
Follow the instruction at the bottom left corner of Vertex window. Connections must be defined correctly ( such as primary and secondary member ) between truss/panel members.
