Stabilizing Pipe Connection (3-D SE)

"Civil Engineering functions" docking window > Steel Engineering > Connections > Front side to web/flange side > Flange > Stabilizing pipe

Use this Design Variant-based function to insert a stabilizing pipe connection between two beams or profiles. Possible beams or profiles are I-beams, U-beams and hollow profiles.

The created connection consists of

one gusset plate on each beam (1),
the connecting pipe with notch (2) and, if required, top plates (4).
one connecting plate (3) on the stabilizing pipe or a T-profile or
one (optional) bolting on the gusset plate or the connecting plate (5).

After calling the function, the Stabilizing pipe connection dialogue window will be displayed.

The configuration of the stabilizing pipe connection takes place on the following tabs:

Beams+Profiles,
Geometry,
Fixing,
Stabilizing pipe and
Weld seams.

Favourites

The settings of the dialogues can be saved as Favourites and reused at any time. To do this, click on the icon at the bottom left of the dialogue window to activate the corresponding menu. More information on Favourites management can be found in the Manage Favourites topic of the HiCAD Basics Help.

Buttons

Preview	While the dialogue window is open you can click on the Preview button to display a preview of the connection according to the current settings. You can use the Zoom functions to enlarge or downsize the image.
OK	Click OK to start the generation of the stabilizing pipe connection. The progress of the generation will be indicated by a progress bar in the status bar. After successful generation of the connection the window will be closed.
Cancel	Click Cancel to close the dialogue window, without generating the connection.
Apply	Like OK, but with the difference that the dialogue window will remain open, allowing you to insert further connections if desired.

Please note:

Gusset plates (and their weld seams) will be assigned to the assemblies of the respective profiles. If such an assembly does not exist, it will be created - with the beam as the assembly main part.
All other elements of the stabilizing pipe connection are combined into an assembly called Assembly Stabilizing pipe.

Beams+Profiles

On this tab you specify which beams are to be connected by the stabilizing pipe connection.

Select - if required, after a click on - the desired beams. For each of the beams you can choose a Usage from the catalogue. Allowed beam types are:

I-beams,
L-beams,
U-beams,
T-beams and
Hollow profiles.

After selecting the beams the position of the stabilizing pipe (depending on the current settings) will be visualized in the drawing. Please note that the selected beam end will affect the position of the stabilizing pipe connection:

Geometry

Here you specify how the stabilizing pipe is to be mounted to the beams. You can do this separately for the mounting to the first beam and the mounting to the second beam using the and button. If you want to use the same parameters for both mountings, click on the button. The settings of the active Pipe-Beam connection will then be applied to the other one.

You can choose between the following two options for insertion of the gusset plates:

	Attaches the gusset plate vertical to the beam.
	Attaches the gusset plate in the direction of the stabilizing pipe and cuts it to the beam.

The required dimensions are:

(1)	Distance of bore grid to the right/left edge of the connecting plate (with regard to the centre of the bore)
(2)	Distance of bore grid to the lower edge of the connecting plate
(3)	Distance of the connecting sheet to the beam
(4)	Distance of the bore grid to the stabilizing pipe
(5)	Distance between connecting plate and stabilizing pipe (not for connections involving T-beams)
(6)	Width of gusset plate
(7)	Height of gusset plate

Fixing

On this tab you specify how the gusset plate and connecting plates are to be inserted and fixed. You can do this separately for the mounting to the first beam and the mounting to the second beam using the and button. If you want to use the same parameters for both mountings, click on the button. The settings of the active Pipe-Beam connection will then be applied to the other one.

You can choose between the following two options to determine the position of the gusset plate:

Enter the distance to the beam end.

Determine the distance by a point.

If you want the gusset plate to be inserted vertical to the chosen beam, activate the checkbox.

Other parameters:
Gusset plate	Click on the symbol and choose the required part from the standard parts catalogue. If required, enter an Offset to the beam, i.e. the distance between the sheet axis and the beam axis. The gusset plate can either be mounted to the front or the back of the connecting plate. This can be chosen in the Positioning field.
Boltings	Here you determine whether gusset and connecting plate are to be bolted together and if so, how. Click on the symbol and choose the components of the bolting. Proceed in the same way as you would do with the 3-D bolting function. The bolting will only be inserted if the Fit checkbox has been activated. Furthermore, you have the option to switch the direction of the bolting by activating the Invert checkbox.
Bore grid	The bore grid determines the arrangement of the boltings on the gusset plate and connecting plate. Enter the number of boltings in X- and Y-direction (max. 2) and the distance between them. If all bores in one direction are to have the same distance, enter the desired distance value in one input field and click on the Equidistant symbol.
Fillets	If you want to fillet gusset plates and connecting plates, activate the corresponding checkbox and enter a fillet radius.

Stabilizing pipe

On this tab you specify the parameters for the connecting pipe and the connecting plate. Instead on a connecting plate reaching "into the pipe" you can also use a small T-beam that will be mounted to the end of the stabilizing pipe. Choose a connecting pipe and a connecting plate.

Choose the desired procedure - Connecting plate or T-beam - and choose the desired connecting pipe from the catalogue. If you want to rotate the connection 90 degrees, activate the corresponding checkbox.

Connecting plate

Choose the desired connecting plate from the catalogue.

If you want to attach a Top plate to the end of the connecting pipe, activate the Create checkbox and enter the distance (1) of the top plate to the edge of the connecting pipe (5). Choose the option for the filleting of the plate from the listbox:

Do not fillet,
Automatic fillet radius determined by HiCAD,
Enter a specific fillet radius.

T-beam

Choose the desired T-beam from the catalogue.

Left: Top plate on connecting pipe; Right: T-beam

A Usage for the pipe can be chosen from the listbox.

Weld seams

On this tab you determine which weld seams are to be created.

Specify where you want to create weld seams by activating the corresponding checkboxes. For each edge you can choose the type of thickness designation, the weld seam thickness, the weld seam type and the inspection category. If you require a Circumferential seam, activate the same-named checkbox.
