Project: HiCAD Steel Engineering

Stabilizing Pipe Connection

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

This Design Variant connects

two beams of the type I-beam, L-beam, T-beam, U-beam or hollow profile, or
two Steel Engineering plates

with a stabilizing pipe.

When connecting the beams it is also possible to mount the stabilizing pipe to plates that already exist on beams.

The created connection consists of

one gusset plate on each beam (1) - if no plates are used that already exist on the beam, or if the insertion of gusset plates has been deactivated.
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.

Please note:

Gusset plates (if they are created by the variant) 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. In the case of the beams, the connection can supply the gusset plates for the connection, or you can also use plates that are already exist on the beam.

Connecting of beams

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.

If a usage has already been assigned to the assembly of the beam, the Overwrite usage checkbox can be used to specify whether the existing usage is to be kept or replaced by the usage type selected on the Beams + Profiles tab.

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:

Click on the symbol to restore the settings on this tab to defaults.

Connecting of beams with mounting to existing plates

If you want the stabilizing pipe to be mounted to plates that already exist on the beams, you can, in addition to the beams, the desired plates. To do this, activate the corresponding checkbox in the Plates area, choose the plate and specify a point for the centre of the bore grid of the mounting.

Please note the following:

The selected plates must already exist on the beams. A is the plate on the first beam, B the plate on the second beam.
If no point is determined for the centre of the bore grid, or if the point specification is cancelled, the corresponding checkbox beneath Plates will be automatically deactivated.
The options for insertion of gusset plates on the Fixing tab will be locked in this case.

In the image below, the two beams (1) and (2) were identified first. After this, the checkbox A in the Plates area of the dialogue window has been activated. The gusset plate (3) on the first beam was chosen as the plate, and the mid-point of the gusset plate edge was chosen as the point. After this, the same procedure was applied to Plate B (4).

Connecting of plates

If you want to insert the stabilizing pipe always between plates - independent from beams - activate the Existing plates checkbox. In the Plates area, activate the corresponding checkbox, select the plate and determine a point for the centre of the bore grid of the fixing.

Please note the following:

If no point is determined for the centre of the bore grid, or if the point specification is cancelled, the corresponding checkbox beneath Plates will be automatically deactivated.
The plate must be parallel to each other and the points must lie in one plane.
The options for insertion of gusset plates on the Fixing tab will be locked in this case.

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.

By activating the corresponding checkboxes you can determine whether the gusset plate is to be

inserted, or whether the stabilizing pipe is to be directly mounted to the flange,
inserted vertically on the corresponding connection, and
mounted to the flange.

Left: Mounting to flange; Right: without

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.
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.
Stabilizing pipe	Here you can specify whether the gusset plate is to be mounted on the front or rear flange, and the stabilizing pipe is to be mounted ft the front or the back of the connecting plate (e.g. T-profile). Furthermore, you can determine whether the gusset plate is to be mounted to the front or back of the connecting sheet or T-profile, respectively. Also, you can rotate the connecting plate and T-profile 90° by activating the corresponding 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.

Please note that the options for gusset plates are not available if you have chosen to use Existing plates on the Beams+Profiles tab.

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. The default setting is Stabilizing pipe.

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.

For continuous HV and HY weld seams, enter 0 as the weld seam thickness.
