Double Horizontal Leg Brace

Used to parametrically generate a connection between two brace members and a vertical (leg) member.

The Double Horizontal Leg Brace connection is intended for use with substation trestles. This tool can also be used on any pipe or hollow HSS tube supporting shape with equal or unequal leg angles as connecting shapes.

Plate tab

Used to input connecting plate geometric values.

Setting	Description
Thickness	Sets the thickness of the plate. Denoted with 1 in the diagram.
Outer Side Gap	Sets the width of the plate at the outside of the horizontal braces. Denoted with 2 in the diagram.
Inner Side Gap	Sets the width of the plate at the inside of the horizontal braces. Denoted with 3 in the diagram.
Gap End	Sets the gap between the ends of the horizontal braces and the trestle leg. Denoted with 4 in the diagram.
Tolerance	Used to set a gap where the plate contacts the trestle leg. Denoted with 5 in the diagram.

Hole tab

Used to specify bolt hole arrangement for bolted connections of braces to plate.

Setting	Description
Distribution in Cross Shape Direction / Distribution in Shape Direction	Used to define hole rows in two directions relative to the horizontal brace member's axis. Number - Specifies the number of bolt rows for each direction. Edge Distance - Sets the distance from the horizontal brace edge to the center of the first hole row for each direction. Denoted with 1 and 3 in the diagram. Distance Between - Sets the distance between hole rows for each direction. Denoted with 2 and 4 in the diagram.
Hole/Slot	Used to specify the geometry of the bolt holes for the connections. Round or slotted holes can be used. Hole Diameter - Specifies the diameter of the holes. Work Loose - Sets the clearance between bolt diameter and hole diameter. Slot Rotation - Used to rotate the slotted holes. Slot Length - Specifies the length of the slotted holes..

Bolt/Weld tab

Used to specify bolt and weld material data, as well as select the connection method used.

Setting	Description
Bolt	Without Bolts - When on, bolts are not included in the connection. Disables the Bolt Style option. Bolt Style - Selects the bolt style from the drop-down list.
Bolt Style	Selects the bolt style from the drop-down list.
Turn Bolts	When on, the bolts are turned before insertion.
Weld Style	Selects the weld style from the drop-down list. The Weld option must be on to enable the Weld Style drop-down list.
Weld	Defines the welding of the brace. Settings found here are enabled when Welded is checked on the dialog's Hole tab. Weld Style - Selects the weld style from the drop-down list. Two Sides Welding - When on, the selected Weld Style is applied to two sides of the brace. Three Sides Welding - When on, the selected Weld Style is applied to three sides of the brace. L-Shaped Welding - When on, the selected Weld Style is applied in an L shape on the brace.
Create Holes/Slots with Bolts	When on, bolt objects are also be created for the connection, along with the bolt holes.
Create just Holes/Slots	When on, only the holes are created for the bolted connection.
Weld	When on, welds are used instead of bolts. Enables the Weld Style drop-down list.

Gusset tab

Used to specify geometry for the connecting gusset plate.

Setting	Description
Thickness	Sets the thickness of the plate. Denoted with 1 in the diagram.
Height	Sets the overall height of the Gusset. Denoted with 2 in the diagram.
Chamfer Distance	Sets the size of the chamfer corners. Denoted with 3 in the diagram.
Offset	Sets the offset between the edges of the plate and the gussets. Denoted with 4 in the diagram.
Create Middle Gusset	When on, a middle gusset is created between the horizontal braces.
Parallel To Leg	When on, the Gusset plate is aligned to the trestle leg it is attached to. When off, it is aligned with the horizontal brace.

Group tab

Used to create a new OpenBridge Modeler group with the Substation Gallery objects.

Setting	Description
Create Group	Select this option to select additional shapes. Separate Substation Gallery objects are created.

Assignment tab

Used to assign elements in the connection to a material, display class, area class, part family, level, etc.

Dialog Controls

Setting	Description
OK	Closes the dialog and save your changes.
Cancel	Closes the dialog without saving changes.
Help	Opens online help.
Template	Saves and retrieve (Using Templates) settings to be used on other projects.
Clone	Shifts focus to the geometry, allowing cloning the current structural object (stair, frame, truss, etc.) properties to match one or more objects selected in the view.
Show /Hide Preview	Opens or closes, respectively, a flyout panel to display an illustration based on the tool.
