Administrator's release notes: Reinforcement improvements

The new simplified bar geometry definition allows you to report, number and export rebars that are modeled with complex geometry in a simplified manufacturable format. There are also changes related to leg surfaces and changes in the attachment of rebar set bars.

For more information about these improvements and changes, see Reinforcement improvements in the Tekla Structures 2023 release notes.

Update the rebar catalog for changes in the Rebar shape manager

  1. Open the rebar_database.inp file in a standard text editor.
  2. Add the Extra point shortening, Curve tolerance, and Max curve radius requiring bending fields.
  3. Save the rebar_database.inp file and copy it to the profil or catalogs folder for your environment.
  4. If your model templates include the rebar catalog, update your model templates.

Add new shapes to the Rebar shape manager

If you do not use the default environment, add new shapes to the RebarShapeRules.xml file in your environment.

For more information, see Define reinforcing bar bending shapes in Rebar shape manager.

  1. On the File menu, click Editors > Rebar shape manager.
  2. On the Shape catalog tab, add the shape for polycurve arc bar.
  3. Add new shapes for any other polycurve shapes that have not been previously supported.

Add new options to the Rebar shape manager

In the Rebar shape manager, you can now use the template attributes USAGE and USAGE_VALUE as custom properties in bending shape rules.

Add these options to the RebarShapeManager.CustomProperties.dat file or merge the file from the common environment with your customized RebarShapeManager.CustomProperties.dat file:
USAGE            String        TextValue
USAGE_VALUE      Integer       NumericValue

Update the objects.inp file for changes in shape recognition

If your environment does not use the objects.inp file in the common/inp folder, you must update your objects.inp file to make the new Shape recognition tab in UDAs for rebar visible.

  1. In the environment folder, open the objects.inp file in a standard text editor.
  2. Add the following lines to the "Reinforcing bar attributes" section:
    tab_page("","albl_Shape_recognition",6)
      {
        attribute("RSR_EXT_POINT_SHORT", "albl_Extra_point_shortening", float, "%d", no, none, "0.0", "0.0")
        {
            value("", 0)
        }
        attribute("RSR_CURVE_TOLERANCE", "j_d_j_tol_curve", float, "%d", no, none, "0.0", "0.0")
        {
            value("", 0)
        }
        attribute("RSR_MAXCURVE", "albl_MAXCURVE", float, "%d", no, none, "0.0", "0.0")
        {
            value("", 0)
        }
        attribute("RSR_FORCE_STRAIGHT", "albl_Force_straight", option, "%s", no, none, "0.0", "0.0")
        {
            value("", 2)
            value("j_No", 0)
            value("j_Yes", 0)
        }
      }
  3. Save the file.

Update advanced options for changes in shape recognition

If you do not want to use the default values for the new advanced options, update them in the environment.ini or role.ini file.

The default values are:

  • XS_REBAR_RECOGNITION_EXTRA_POINT_SHORTENING: 0.3

  • XS_REBAR_RECOGNITION_MAXCURVE: 304800

  • XS_REBAR_RECOGNITION_CURVE_TOLERANCE: 12.7

  1. Open the environment.ini or role.ini file in a standard text editor.
  2. Change the values of the new advanced options.
  3. Save the file.

Update your customized files for changes due to short leg and long leg suffixes for rebar sets

  1. Copy the objects_couplers.inp from the common environment or merge the file from the common environment with your customized objects_couplers.inp file.
  2. If your environment does not use the common\inp folder, add the objects_couplersSL.inp file to the folder defined by the XS_INP advanced option.
  3. Modify the RebarShapeManager.CustomProperties.dat file to support both the existing start and end prefixes, and the new short leg and long leg prefixes, or merge the file from the common environment with your customized RebarShapeManager.CustomProperties.dat.

    Example contents of the modified file:

    
    PREFIX              String      TextValue
     
    ENDPREP_START       Integer     NumericValue
    THREAD_TYPE_START   String      TextValue
     
    ENDPREP_START       Integer     NumericValue
    THREAD_TYPE_START   String      TextValue
     
    //
    // Short leg OR long leg specific custom properties
    //
    METHOD_S            Integer     NumericValue
    TYPE_S              Integer     NumericValue
    PRODUCT_S           String      TextValue
    CODE_S              String      TextValue
    ENDPREP_S           Integer     NumericValue
    THREAD_TYPE_S       String      TextValue
    THREAD_LENGTH_S     Double      DistanceValue
    EXTRA_LENGTH_S      Double      DistanceValue
    FREE_1_S            Double      DistanceValue
    FREE_2_S            String      TextValue
    //
    METHOD_L            Integer     NumericValue
    TYPE_L              Integer     NumericValue
    PRODUCT_L           String      TextValue
    CODE_L              String      TextValue
    ENDPREP_L           Integer     NumericValue
    THREAD_TYPE_L       String      TextValue
    THREAD_LENGTH_L     Double      DistanceValue
    EXTRA_LENGTH_L      Double      DistanceValue
    FREE_1_L            Double      DistanceValue
    FREE_2_L            String      TextValue
  4. Modify the RebarCoupler.Udas.dat file to add End preparations to the Coupler and End anchor plug-in dialog boxes.
    1. Open the RebarCoupler.Udas.dat file in a standard text editor.
    2. Add the following line to the file:
      REBAR   option      EndPrepLeft     EndPrepRight        ENDPREP_START           ENDPREP_END         j_d_j_End_preparation
    3. Save the file.
  5. If you do not use the standard files from the common environment, update these standard files:
    • standard.RebarCoupler.CouplerForm.xml standard file for the Rebar coupler tool

    • standard.RebarCoupler.EndAnchorForm.xml standard file for the Rebar end anchor tool.

    Add default values for End preparation on the Rebar attributes tab.
