To Place a Joist Girder

Select

(Place Joist Girders ). The Place Joist Girder mode selection dialog appears.

Select the Place mode. You are prompted to enter start and end points.

Datapoint start and end points a certain distance apart. After the second datapoint is chosen, the Place Joist Girder dialog appears.

Select a span from the Spans Tree. The tree expands by one level revealing another set of options for girder spaces.

Note: Only those spans which are greater than or equal to the span defined by the datapoints are displayed in the span tree.

Select from the girder spaces list. This determines how many panels are in the joist girder assembly. The tree expands again revealing another set of options for joist depth.

Select a depth for the joist girder.

Note: Settings on the right side of the dialog labeled Properties (Span, Mark, Girder Spaces, Depth, Panel Point Load and Seat Depth) are automatically filled in with corresponding values from the spans tree. These can be changed at any time as they represent just the most common scenarios for that particular span/panel point/depth configuration.

Define the bearing end properties like bearing distances and seat heights for each end of the joist girder on the End1 and End2 Details tabs.

Tip: Values set are retained for subsequent joist girder definitions.

Review the preset section and part/family data for the joist girder assembly components on the Member Info tab. Select different sections and part/family data for some components using the drop lists.

Tip: The section drop lists are populated with common sections loaded by the JoistGrider.xml settings file (located in the active dataset folders).

Chose the level of model detail for the joist girder from the Preferences tab. You can model detailed members or only an envelope member.

Note: The joist envelope approximates the outer boundaries of the joist girder assembly. The name of the envelope section is set by the series and depth selected in the Spans Table, and is automatically appended to active section file.

Click Place to complete the modeling of the joist girder.

The joist girder assembly is placed in the DGN file as a compound cell.
