Improvements in components

Improvements in components

There are several improvements in concrete components and steel components in Tekla Structures 2020.

 

Concrete components

Component Description

Floor layout

  • You can now define property strips that have certain properties and detailing components, and use the property strips according to your needs in the floor layout. Note that property strips only affect the main layer parts.

    To define a property strip, click on the contextual toolbar of Floor layout. This opens a dialox box where you can define the property strip, and select which detailing component is used.

    Property strips are added as lines in the floor layout plane. Property strips affect the parts that they are touching. You can also set property strips so that they affect through the slab line.

    The image below shows an example of a property strip. The two slabs have a different class and profile because of the property strip.

    Note that property strips cannot change the width of the line of slabs. Define the width using the width properties of Floor layout.

  • You can now use the new CIP filler parts tab to control the creation and properties of all CIP filler parts. Previously, you used the separate Floor layout CIP filler component to do this. Floor layout creates the filler parts together with any other floor parts.

    In addition to the empty areas in floors, CIP filler parts can be created when:

    • The allowed slab width is smaller than the needed width.

    • The opening is larger than needed because of allowed width zones.

    • The slab is split into two because of a large opening.

    • The slab nose is not created because it is too narrow.

  • You can now define the maximum slab length on the Advanced tab. If the slab length is longer than the given maximum length, the slab is not created.

    In addition, you can now define the profile and width specific minimum/maximum lengths in the FloorLayout.ini file as shown below. If the file contains any values for the profile, these values will be used and they override the minimum/maximum lengths defined in the Floor layout dialog box.

    /
    // Min/max lengths by slab profile & width min/max
    //
    // Profile Width min/max Length min/max
    SLAB_LENGTH P20(200X1200) 0-1200 2000-9000
    SLAB_LENGTH P32(320X1200) 0-601 2500-10000
    SLAB_LENGTH P32(320X1200) 601-1200 2500-12000
  • The floorlayout.objects.inp file can now be located in the model folder, or in any of the folders set in the XS_FIRM, XS_PROJECT, orXS_SYSTEM advanced options.

  • You can now use the new Align the openings by allowed widths option on the Advanced tab. Select Yes to re-align the opening/cut longitudinal edges to match the allowed width zones. The default value is No. Existing floor layouts are not affected until you modify the option value to Yes.

  • When Floor layout is updated, the GUIDs of the first and last end slabs are not changed. This ensures that any detailing, such as wire loop notches made to the first or last slabs, is maintained as far as possible.

Wall layout

  • The WallLayout.Udas.dat file can now be located in the model folder, or in any of the folders set in the XS_FIRM, XS_PROJECT, or XS_SYSTEM advanced options.

  • In Wall layout connector, you can now define how the parts forming the turning corner are modeled. When you select this option, Wall layout connector creates an additional part that is added to the cast unit. The turning corner part is created with the (first) name given in the system file SandwichWallCornerPartNames.dat.

Mesh bars / Mesh bars by area

  • You can now define user-defined attributes (UDA) for reinforcing bars on the Attributes tab. You can select for which rebars the UDAs are defined, or you can define them for all rebars. UDAs can be set for the rebars in reinforcing bar groups and meshes.

    The UDAs are predefined in the meshbars.udas.dat file. The file can be located in any of the folders set in the XS_FIRM , XS_PROJECT, or XS_SYSTEM advanced options, and in the model folder.

  • You can now set the bar edge distance as a negative value. Note that this will only offset the bars. To get a fully offset mesh, set the cover thickness for the sides on the Bar end conditions tab to a negative value.

  • On the Detailing tab, the Create cuts around selected parts function has been improved. Filter recognition in the list of filters has been improved and the selected filter is now visible when you reopen the component dialog box in the model.

Geometry detailing strip

  • You can now define the strip offset from the input line.

  • You can now select how the cut is modeled. The options are Cut only, Cut and part, and Part only.

  • You can now control the properties of the created part. With the Use main part properties option, the added part gets the properties of the main part. Otherwise, you can select the saved standard attributes for the concrete beam.

    Note that if you change the saved properties afterwards, you need to modify the geometry detailing strip to get the properties of the added part updated.

Sandwich wall vertical seam

On the Rabbets tab, there is now a new tongue joint connection type based on the center line and a new groove joint connection type based on the outer geometry.

    • You can select whether to cut the meshes at void locations.
