Notes on assembly structures:

When you insert the Base plate + Anchor plate connection, the following assemblies will be created (depending on the current configuration) as a result:

The base plate and the ribs will be assigned to the assembly of the selected beam (the column). The assembly main part is the beam.
Filler plates and inserts will be assigned to the structure assembly Loose part. This assembly is located on the same structure level as the column assembly.
If you have selected the assignment option Loose part for bolting insertion, the bolting will be placed in an assembly called Bolting and will also be assigned to the structure assembly Loose Part, or otherwise to the assembly of the column.
A further assembly contains the shear connector as assembly main part, the head studs, the welded plate and the anchor plate. The head studs are placed into a non-BOM-relevant assembly called Standard part group. If you have chosen the insertion of threaded studs instead of the bolting, these will also be assigned to this assembly, with studs, nuts and washers each being placed into one assembly called "Standard part group".
Weld seams always assigned to the assembly to which the corresponding plate, rib or stud belongs, i.e.
Beam - Base plate Assembly of beam
Beam - Rib Assembly of beam
Rib - Base plate Assembly of beam
Anchor plate - Welded plate Assembly of anchor plate
Anchor plate- Shear connector Assembly of anchor plate
Head stud - Anchor plate Assembly of anchor plate

Please also note:

HiCAD will indicate the top/bottom/right/left positions in the drawing during input of the required data. The texts will be aligned in Z-direction.

The components of the base plates and anchor plates will be loaded from the HiCAD Standard part catalogues. If you wish to use your own beams, profiles, plates, bolts etc. you need to expand the corresponding tables in the Catalogue Editor accordingly.

Manage configurations

Configurations for Base plates+Anchor plates can be saved, which enables you to access your individual configurations at any time afterwards.

More about configurations

Configure base/anchor plate

The base plate/anchor plate connection is defined by the settings on the following tabs of the dialogue window:

Plates,
Fixing,
Bore grid,
Galvanization,
Weld seams,
Filler plate,
Shear connector,
Head studs and
Ribs.

Plates

Here you specify type and size of the base plate, weld-on plate and anchor plate and their alignment in relation to the selected beam.

The settings for the different plates takes place on the sub-tabs on the left side of the window. Anchor plates and welded plates are only inserted if you have activated the Create checkbox on the corresponding sub-tab.

Create	Anchor plates and welded plates are only inserted if you have activated this checkbox on the corresponding sub-tab.
Congruent (Base plate)	If you want the anchor plate or welded plate to be congruent with the base plate, activate this checkbox. no value inputs in the Vertical/Horizontal fields will then be required.
Semi-finished product	Click the icon to select plate type and material directly from the corresponding standard part catalogues. Various semi-finished product types, e.g. flat steel, offer the option to rotate the plate before insertion: To do this, activate the Rotate (Flat steel) checkbox.
Vertical	Height, projection top Plate height and plate projection at top Height, projection bottom Plate height and plate projection at bottom Height, centred on beam Plate height. The plate will be centred vertically at the end of the beam to be connected. The projections will be calculated automatically. Projections beyond beam Projections beyond the first beam at top and bottom. The plate height will be calculated automatically.
Horizontal	Width, projection left Plate width and projection to the left Width, projection right Plate width and projection to the right Width, centred Plate width. The plate will be centred horizontally at the end of the beam to be connected. The projections will be calculated automatically. Projections beyond beam Projections to the left and right. The plate height will be calculated automatically.
Clearance	If desired, enter a value for the clearance here, i.e. Base plate: Distance to beam, Welded plate: Distance to base plate and Anchor plate: Distance to welded plate.
Fillet corners	If you want the corners of the plate to be filleted, activate this checkbox and enter a fillet radius.
Shorten beam by plate thickness	Activate this checkbox if you want to shorten the beam by the thickness of the plate that is to be mounted onto the beam. The thickness of pre-planned filler plates and the clearance of the base plate (distance to beam) will be taken into account in the process. The selected beam will always be shortened by the thickness of the pre-planned filler plates and the clearance between base plate and beam, even if the Shorten beam by plate thickness checkbox has not been activated on the sub-tabs of the different plate types.
Rotate (Flat steel)	Various semi-finished product types, e.g. flat steel, offer the option to rotate the plate before insertion: To do this, activate the checkbox.

Fixing

Here you specify whether the fixing is to be done by means of boltings or threaded studs.

To do this, activate the corresponding Fit checkbox. The relevant input fields will then be active.

Boltings
If you want the fixing to be done by means of boltings, activate the Fit checkbox here and specify the components of the bolting by clicking on the symbol. The procedure is similar to that for the New bolting/riveting function. All plates will then be bolted together.

Instead of the boltings you can also insert only bores, i.e. the plates will only be pre-drilled. To do this, activate only the Bores checkbox.

Beneath Assignment you determine to which assembly the boltinmgs are to be assigned. If the option Loose part has been activated, the boltings will be placed into a separate assembly. If the option Assembly has been activated, the bolting assembly will be assigned to the column assembly.

Inserts
If the Fit checkbox beneath Boltings has been activated, the Inserts area will also be made available for inputs.
If you want to fit Inserts, activate the corresponding checkboxes here. Click the icon and choose the part from the catalogue. Specify the length. Activate the Rotate 90° checkbox to rotate the part before insertion.

Threaded stud
If you want the fixing to be done with threaded studs, Activate the Fit checkbox here - the areas Boltings and Inserts will then be greyed out. Select the desired stud (Semi-finished product) , Nut and Washer. Base plate and welded plate will then be connected by means of the threaded studs.

Usage (Assembly)
Here you can specify the usage of the selected beam and the shear connector.

Please note that the usage can only be set before the creation of the assembly structure. As soon as you click the Preview button or the OK button, a change is no longer possible.

Bore grid

The bore grid determines the arrangement of the bores, the boltings and the threaded studs on the plate.

For both the horizontal and the vertical settings you need to select a reference first. Further inputs are then dependent on the selected reference.

Horizontal - Reference	Inputs
Distances to plate edge	Number of bores to the left of the web Number of bores to the right of the web Distance of bores to the left plate edge Distance of bores to the right plate edge Distances between the bores
Inner distance	Number of bores to the left of the web Number of bores to the right of the web Inner distance of bores Offset with reference to the web Distances between the bores
Distances to web	Number of bores to the left of the web Number of bores to the right of the web Distance of bores to the left of the web Distance of bores to the right of the web Distances between the bores

Vertical - Reference	Inputs
Centred (Front plate)	Number of bores Vertical distances between bolts
Ref. beam, upper edge	Distance to upper edge of reference beam Number of bores Vertical distances between bolts
Front plate, top	Distance to upper edge of plate Number of bores Vertical distances between bolts
Ref. beam, lower edge	Distance to lower edge of reference beam Number of bores Vertical distances between bolts
Front plate, bottom	Distance to lower edge of plate Number of bores Vertical distances between bolts

You can use different vertical distances between bores. If you want all vertical distances between bores to be equal, the easiest way to achieve this is to enter the desired distance value in one input field and click the Equidistant icon. All input field will then be filled with the same value.

Galvanization

Here you specify whether you want to apply holes for galvanization processes to the base plate and the reference beam. Activate the corresponding sub-tabs on the left hand side for this purpose.

On beam

Here you select the desired processing. Possible are the following settings:

- (no processing)
Web cut
Choose whether the processing is to be applied at the top or bottom and enter a radius.
Holes
Choose whether the processing is to be applied at the top or bottom. Enter a hole diameter and the distance in X- and Y-direction.

Base plate

Use the checkboxes to specify which bores are to be created. Enter a hole diameter and the minimum distance to web and flange.

(1) Processings on beam: Holes, holes in plate, (2) Processings on beam: Web cut at top/bottom, holes in plate

Weld seams

Here you specify, by activating or deactivating the checkboxes, which weld seams are to be created between beam and base plate. The following options are possible:

a circumferential seam,
weld seams on particular edges, or
all weld seams.

For each edge you can select a type of thickness designation, the weld seam thickness, the weld seam type and the inspection category. If you want to use the same settings for the other edges, click the Equate icon.

In addition, you can specify here whether weld seams are to be inserted

on the ribs (between beam and ribs, and between ribs and base plate),
between anchor plate and welded plate,
between anchor plate and shear connector,
between anchor plate and head studs and
between anchor plate and threaded studs.

To do this, activate the Fit checkbox and enter the weld seam thickness. In the listbox for the Inspection category you can select the test/inspection method according to DIN EN 1090. These inspection categories are predefined in the Configuration Editor at Modelling > Weld seams. They will be evaluated during creation of Weld Seam Test Protocols.

Filler plate

If you want filler plates to be fitted between base plate and welded plate, you can specify the number of plates, the type and the size of these plates here.

The following geometry types are available:

One-piece, insert left,
One-piece, insert right,
One-piece, insert top,
One-piece, insert bottom,
One-piece, drilled,
Two-piece, insert horizontal and
Two-piece, insert vertical.

Enter, depending on the selected geometry type, the required distances and a value for the hole clearance. The hole clearance always refers to the bolting.

(1) Bolt diameter, (2) Two-piece filler plate, (3) Hole clearance

Beneath Manage you can specify the number of the filler plates.

For each filler plate, select the desired sheet type from the catalogue and specify, by activating or deactivating the corresponding checkbox, whether the filler plate is to be pre-planned or not. If the filler plate has been defined as "pre-planned", the beam will be shortened by the thickness of the filler plate. Non-pre-planned filler plates will be created beside the beam.

Use the icon to apply the settings on one filler plate to all other filler plates.

By activating the All checkbox, all filler plates can be defined as Pre-planned.

Please note that non-pre-planned will be displayed as transparent parts in the drawing, i.e. they will be assigned to Layer 40.

Non-pre-planned filer plates

Filler plates are not assigned to the assembly of the beam, but will be placed in a separate structure assembly called Loose parts. They obtain the usage Filler plates.

If the bore grid is too narrow, preventing the fitting of filler plates, the plate will not be created. However, a feature log entry will be created.

Double-click the name of the feature to change the settings.

Shear connector

Here you determine the profile for the shear connector, its length and its material. Click the icon to select the profile and the material directly from the corresponding standard part cataogues.

Beneath Positioning you can specify an offset of the shear connector in relation from the plate.

Head studs

Here you specify whether head studs are to be fitted. If so, activate the Fit checkbox and select the desired bolt.

Beneath Positioning you determine how the head studs set is to be aligned horizontally or vertically on the plate.

Ribs

Here you have the option to attach additional stiffeners - so-called ribs - to flange or web.

For each of the possible stiffeners (2 and 5 to web, 1, 3, 4, and 6 to flange), the following parameter settings are possible:

Fit
By activating or deactivating this checkbox you specify whether the corresponding stiffener will be inserted or not.

AutoCalculate length
If this checkbox has been activated, the length of the stiffeners will be automatically calculated. If you do not want this, deactivate the checkbox and enter the length yourself.

Height, Chamfer X, Chamfer Y
Here you specify the height of the stiffener and the chamfer length in X- and Y-direction.

Process corner
Here you define the processing of the inner corner of the of the stiffener. Possible settings are:

None
Chamfer
Inner fillet
Outer fillet

Depending on the selected option, enter either the chamfer length or the fillet radius.

Click the icon to apply the settings specified in the current input area to all other stiffeners in this direction. For instance, if you process area 1, i.e. in flange direction, and then click on the icon, the settings in the areas 3, 4 and 6 will be adjusted automatically.
