Example of definition of point reinforcement

The following example illustrates the definition of point reinforcement in the cross section of the beam. For definition of the beam contours the Formworks - Beam macro has been used.

To define point reinforcement in the beam:

1. Define transversal and longitudinal reinforcement

DEFINITION OF THE BEAM FORMWORK

1. Run the Formworks - Beam macro by clicking .
2. In the Formworks - Beam dialog, specify the following parameters:
   • section type: 1 (rectangular)
   • beam type: 1 (single-span beam)
   • dimensions of the beam cross section: height = 600 mm, width = 300 mm
   • beam geometry displays as follows:
   
3. Click Insert in the Formworks - Beam dialog.
4. Indicate the location of the beam formwork in the drawing.

DEFINITION OF THE BEAM REINFORCEMENT

1. Click the Reinforcement - cross-section icon
2. In the Reinforcement - cross-section dialog, specify the following parameters:
   • type of reinforcing bars: polygon-shaped (closed) stirrup
   • bar diameter: 8 mm; cover of reinforcing bars: 30 mm
   • steel grade: R
   • shape parameters as shown in the drawing below
   
3. Click (Pick point).
4. In the drawing of the beam formwork indicate a point within the beam cross section and point 1 that determines the position of stirrup hooks.
5. Accept the deafult reinforcement description proposed in the Reinforcement description dialog by clicking OK.
6. Indicate the position of the reinforcement description in the drawing by clicking Enter, or right-clicking the Enter option from the context menu.

Define the straight longitudinal reinforcement (with the reinforcement in the beam cross section already defined), as follows:

1. Click the Reinforcement - elevation icon
2. In the Reinforcement - elevation dialog, specify the following parameters:
   • type of reinforcing bars: straight bar
   • bar diameter: 12 mm; cover of reinforcing bars: 30 mm
   • steel grade: R
   • shape parameters as shown below
   
3. Click (2 points).
4. In the drawing of the beam formwork, indicate point 2 and point 3.
5. Accept the deafult reinforcement description proposed in the Reinforcement description dialog by clicking OK.
6. Indicate the position of the reinforcement description in the drawing by clicking Enter or right-click the Enter option from the context menu.

Once the transversal and longitudinal reinforcement is defined, define the point reinforcement as follows:

1. Click the Reinforcement - point icon
2. Indicate the defined longitudinal bar.
3. Specify the following parameters; bar distribution: regular
4. Click (Whole segment), indicate the upper part of the defined stirrup, and click Enter.
5. Specify the following parameters:
   • number of bars n = 3
   • leave default values of the remaining parameters
6. Click OK.
7. Adopt the following parameters of the description of reinforcement distribution:
   • type of reinforcing bar representation: all
   • position: the Active option switched on
   • type of distribution description:
8. Click OK.
9. Indicate the position of the reinforcement description in the drawing by clicking Enter or right-clicking the Enter option from the context menu.

The defined point reinforcement is presented in red in the drawing below:
