Improvements in components

There are several improvements in concrete components and steel components in Tekla Structures 2022.

Tekla Structures 2021 service packs also introduce improvements to components, see 2021 SP7: Important improvements and fixes, 2021 SP6: New features and improvements, 2021 SP5: New features and improvements, 2021 SP4: New features and improvements, 2021 SP3: New features and improvements, 2021 SP2: New features and improvements, and 2021 SP1: New features and improvements.

Concrete components

Tapered I beam (81) - new concrete component

Tapered I beam (81) creates beams with multiple types of cross-sections and height variations. The component has many useful features:

  • More cross-section types: I, T, inverted T, and rectangular

  • More options for dimension input

  • Possibility to use end details

  • Possibility to define user-defined attributes

Tapered I beam (81) replaces the Concrete var beam (S52) component that is no longer available in the Applications & components catalog in Tekla Structures 2022. Note that if you have used Concrete var beam (S52) in your models, you can still open the component properties dialog box by double-clicking the component in the model and and modify the properties, if needed.

Component Description

Floor layout

  • Allowed cut zones enable you to define where it is allowed to make a cut for each profile type. These settings are defined in the FloorLayout.ini file.

    On the Advanced tab, you can now use Slab widths and cut zone settings to select the FloorLayout.ini that the component is using. The list contains all the FloorLayout.ini files that are available.

    The Default option is the file named as FloorLayout.ini. You can create multiple settings and save these settings in your own xxxx.FloorLayout.ini file, for example, MyOtherSetting.floorlayout.ini.

  • You can now define the allowed slab width, and the allowed locations of cuts and lengths in the FloorLayout.ini file. You can do this by adding a line in the FloorLayout.ini file starting with the key word CUT_ZONES, for example:

    SLAB_WIDTH P32(320X1200) 380-560 660-860 930-1110
    CUT_ZONES P32(320X1200) 360-580 640-880 910-1130

    If CUT_ZONES are not defined for a certain slab profile, the zones given on a SLAB_WIDTH row are used both for aligning the slab widths and the opening cuts, as before.

  • There is a new button in the Floor layout contextual toolbar.

    This button is visible when you have selected the button to modify seam gaps or slab direction. Click the new button to reset all seam gaps and slab distribution to the initial default values that were used when the floor layout was created.

  • There is a new button in the contextual toolbar for adding a circular opening to the floor layout. Pick a center point and the radius to add the opening. You can use direct modification to modify the opening and the offsets at the opening.

    On the Default offsets tab, you can now use the Cutting around setting to control how the automatic cut-outs are made in the selected layer: By rectangle or By shape. When you select By shape, the cut shape is the same as the shape of the part. For example, when the column is round, a round cut is created.

    You can also select not to create the cut. When you select Do not create, automatic cut-outs are not created in the layer.

  • Floor layout now shows the actual slab width and the offsets from the seam center in the model if the actual width is different than the required width because of slab width constraints.

  • On the Layer tab, you can now use the leftmost check box to control if the number of the layers and the order of the layers are modified when you modify the Floor layout component.

Rebar coupler, Rebar end anchor, Rebar split and coupler

On the Parameters tab, there is a new Add to rebar assembly setting.

To add the coupler as a sub-assembly to the rebar assembly, select either Yes, to primary bar or Yes, to secondary bar.

Note that you must first create the rebar assembly, otherwise adding is not possible.

The default value is No.

In Rebar split and coupler, using one of the Yes options will create new rebar assemblies for the new bars created by the split command.

Continuous beam reinforcement, Hollowcore lifting loops, Hollowcore opening tool, Multi wire size mesh, Seam applicator

The default part prefix and position number are now set properly for all parts.

Corbel connection (14), Seating with dowel (75), Two sided seating with dowel (76), Seating with dowel to flange (77), Two sided seating with dowel to flange (78), Embed (1008), Anchor (10), Wall wall teeth (12), Concrete console (110), Concrete console (111), Concrete beam beam (112)

You can now select the saved properties file for custom components by using the selection button.

Lifting anchor (80), Electric box in wall (84)

You can now select the saved properties file for custom components by using the selection button.

Note that you need to update the file to ensure backward compatibility.

Corbel reinforcement (81)

You can now combine the created rebars to a rebar assembly, and also add this assembly to another rebar assembly based on the area intersection of these two.

Round column reinforcement (82), Rectangular column reinforcement (83), Rectangular area reinforcement (94)

You can now use the Rebar assembly tab to define an assembly for the created rebars.

Braced girder (88, 89)

On the Picture tab, you can now add the created braced girders into a rebar assembly if the braced girders are created as reinforcement.

Embedded anchors (8), Embed (1008)

On the Advanced tab, you can now create a rebar assembly from the rebars that are created around the anchors.

Mesh bars / Mesh bars by area

You can now use the Rebar assembly tab to define an assembly for the created rebars.

Slab reinforcement tool

Starting from Tekla Structures 2022, Slab reinforcement tool is by default hidden from the Applications & components catalog. We recommend that you use the Mesh bars component to create reinforcement to irregularly shaped concrete slabs.

Starting from Tekla Structures 2021 SP4:

Formwork placing tools - Walls

The filler configuration file Fillers.csv in Formwork placing tools - Walls has been improved. You can now configure the usage of filler (custom) parts, whose width can be can be varying and/or parametric. Use the new configuration fields:

Part1LengthProperty – the name of the length property of the custom part. This is needed only if/when the length/width is controlled by a parameter instead of input points.

Part1LengthMin – the minimum length/width (the free gap to fill) the product can fit.

Part1LengthMax – the maximum length/width the product can fill.

Part1HeightProperty – the name of the custom part parameter controlling the height of the custom part.

The fields can be set for Part2, Part3, and so on. Also multiple parts with separate additional rows can be configured. Then you need to keep the Supplier, Family, and Name the same as on the first line.

Starting from Tekla Structures 2021 SP4:

Formwork placing tools - Slabs and Formwork placing tools - Walls

You can now setup any formwork accessory item to be created either as a custom part (as before), as an item, or as a beam.

For items or beams it is also possible to setup any of the item or beam properties or the UDAs either in the configuration file by adding new columns, or with the Save as property files.

Formwork placing tools - Slabs

  • On the Panel tab, there are two new properties: Panel widths (in array) and Panel lengths (in array).

    Use these options to modify the panel sizes in the panel array. Alternatively, you can use the new Modify panel dimensions button on the contextual toolbar.

    In addition, the panel array preview is now shown properly when the boundary and/or the array direction and/or the zero (starting) point is modified.

  • Now the TW_TYPE attribute is written for panels, stop ends, and railings.
