Change the cover thickness using direct modification

1. Ensure that the Direct modification switch is active.

2. Select a single reinforcing bar, a reinforcing bar group, or a mesh.

3. Drag a line handle to the desired location.

   

Change the cover thickness using the Single rebar, Rebar group, or Rebar mesh properties

1. Select a single reinforcing bar, a reinforcing bar group, or a mesh.

2. Double-click the reinforcement to open its properties.

3. Define the reinforcing bar cover thickness in the Cover thickness section.

   The cover thickness can be defined in three directions:

   • On plane, that is, the distance from part’s bottom, top, and side faces to the bar.

     You can enter several values. Enter the values in the order you pick the points to create the bar. If you enter less values than there are bar legs, Tekla Structures uses the last value for the remaining legs.

   • From plane, that is, the distance from the end face of the part to the bar.

     If the reinforcing bar is outside the part, enter a negative value in the On plane and/or the From plane boxes.

   • In the longitudinal direction of the bar, that is, start and end.

     To define the length of an ultimate leg of a bar, use the Leg length option and the Snap to nearest points switch. Then pick anywhere on a part edge or line to indicate the direction for the bar leg.

4. Click Modify.

Change the default cover thickness of the rebar sets in a model

1. On the File menu, click Settings > Options to open the Options dialog box.

2. Go to the Rebar set settings and to the Covers and locations tab.

3. Modify the settings and click OK.

   You can define the default cover thickness values in the global and/or parts' local coordinate systems and at different part faces. In each concrete part's properties, you can then select whether to use the global or local cover thickness values.

4. To apply the changes to all or selected existing rebar sets in the model, go to the Rebar tab on the ribbon and click More > Regenerate.

Change the cover thickness of the rebar sets in an individual concrete part or for a part type

1. Double-click a concrete part to access its properties.

2. Go to the Concrete covers for rebar sets section.

   Alternatively, you can click User-defined attributes and go to the Rebar set tab.

3. Select the coordinate system: Global or part's Local.

   If you select the empty option, Tekla Structures uses the global cover thickness values from the Options dialog box.

4. To override the default values from the Options dialog box, define the cover thickness at each required part face.

   • With the Global coordinate system, you can enter the top, bottom, and side face values.

   • With the Local coordinate system, you can enter the top, bottom, front, back, start, and end face values.

5. Click Modify to update the selected part's properties.

6. To save the cover thickness values for later use for this part type, update the standard file or create a property file.

Change the concrete cover thickness of the rebar sets at a concrete part face or pour object face

1. Add a surface to the object face at which you want to change the concrete cover.

2. Double-click the surface to modify its properties in the property pane.

3. In the Type list, select Concrete cover.

4. In the Rebar set section, enter the concrete cover thickness in the Concrete cover box.

5. Click Modify to apply the changes.

NOTE: If you add surfaces to pour object faces, update the rebar sets each time you reopen the model. On the Rebar tab on the ribbon, click More > Regenerate.
