To manually add physical member restraints for
assignment to physical members, use the following procedure.
Manual restraints apply to steel physical members which will be
designed per AS 4100.
Tip: The
restraint details can be automatically generated using a new
Member Restraints item found in the
Utilities ribbon tab in the
Geometry Tools group.
-
In the Analytical Modeling workflow page controls, select the
Design page.
-
Select
AS4100 as the
Current Code in the
Steel Design - Whole Structure dialog.
-
Click
Define Parameters.
The
Design Parameters dialog opens.
-
Select the
PBRACE parameter.
-
For each brace point, specify a fraction of the total physical
member length in the
Brace Location cell.
-
Select the type of restraint present for the top or bottom flange.
Note: Only top or
bottom flange restraints can be described using a single
PBRACE
command. If both top and bottom bracing is
added in the Design Parameters dialog, this will generate two new command lines
in the input file.
-
Click
Add.
The new command appears in the tree as a child element of
the current design parameter set.
-
Click
Close.
The design parameters are marked with an
icon. This indicates that the
need to be assigned to members.
-
Use one of the
STAAD.Pro assignment methods to assign each
parameter to the applicable members.
The
PBRACE
specification is tagged as (Physical), and
therefore can only be assigned to physical members (PMEMBER groups).
