Create a polygonal reinforcement mesh

Create a polygonal reinforcement mesh

You can create a reinforcement meshreinforcement that represents a mesh of steel bars in two perpendicular directions

In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.

that consists of two perpendicular bar groups. Tekla Structures treats meshreinforcement that represents a mesh of steel bars in two perpendicular directions

In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.

bars as one unit but distinguishes the main and crossing bars.

  1. On the Concrete tab, hold down Shift and click Rebar > Mesh.

    The Reinforcement Mesh Properties dialog box opens.

  2. In the Mesh type list, select Polygon.
    Note:

    You cannot change the mesh type once the mesh has been created.

    The reinforcement mesh can be polygonal, rectangular , or bent.

  3. Click OK.
  4. Select the part to reinforce.

    Tekla Structures attaches the mesh to this part.

  5. Pick the start point of the mesh.
  6. Pick the corner points of the mesh.
  7. Click the middle mouse button to finish picking.
  8. Pick a point to indicate the direction of the longitudinal bars.

    Tekla Structures creates the mesh.

  9. If you want to modify the reinforcement, do one of the following:
    • Use direct modification. Ensure that the Direct modification switch is active.

    • Double-click the reinforcement to open the Reinforcement Mesh Properties dialog box and modify the properties.

Reinforcement mesh with holes

If you want to reinforce a part that has holes, you need to pick the corner points of holes when you create the reinforcement.

  1. Select the part to reinforce.

  2. Pick the start point of the mesh.

  3. Pick the corner points of the mesh.

  4. Pick the corner points of the holesmall hollow open throughout a part or assembly that is usually used for fastening parts with bolts or other such objects

    Hole is created in the same way as bolts and hole properties are defined in the bolt properties.

    .

    Note that you need to pick the corner points of the hole in the opposite direction than the corner points in the mesh.

  5. Click the middle mouse button to finish the picking.

  6. Pick a point to indicate the direction of the longitudinal bars.

Reinforcement mesh properties

Use the Reinforcement Mesh Properties dialog box to view and modify the properties of reinforcement meshes. The file name extension of a reinforcement mesh properties file is .rbm.

Option Description
Mesh prefix and start number Mark series of the mesh.
Name

User-definable name of the mesh.

Tekla Structures uses mesh names in reports and drawing lists.

Mesh

Select a mesh from the mesh catalog.

The properties of standard meshes are defined in the mesh_database.inp file.

You can also use a customized mesh.

Grade Steel grade of the bars in the mesh.
Class

Used to group reinforcement.

For example, you can display bars of different classes in different colors.

Mesh type

Shape of the mesh. Select Polygon , Rectangle , or Bent.

For bent meshes, enter the bending radius.

Bending radius Internal radius of the bends in the bar.
Cross bar location Define whether the crossing bars are located above or below the longitudinal bars.
Cut by father part cut Define whether the polygon or part cuts in the part also cut the mesh.
Cover thickness on plane Distance from the part surface to the main bars on the same plane as the bars.
Cover thickness from plane Distance from the part surface to the bar, or bar end, perpendicular to the bar plane.
Start Thickness of concrete cover or leg length from the mesh starting point.
End

Thickness of concrete cover or leg length at the end point of the bar.

Used for bent meshes.

User-defined attributes

You can create user-defined attributes to add information about reinforcement. Attributes can consist of numbers, text, or lists.

You can use the values of user-defined attributes in reports and drawings.

You can also change the name of the fields, and add new ones, by editing the objects.inp file. See User-defined attributes (UDAs) in the objects.inp file.

Hooks tab See Add hooks to reinforcing bars.
