Member data for the automatic reinforcement design

General

Name

Specifies the name of the member data.

 

Max. exploitation of cross-section

Specifies the maximal utilisation of the cross-section in the automatically reinforced beam.

The value may be between 1 and 100 %.

 

Reinforcement template

Shows the used reinforcement template.

Note: This item appears in the dialogue ONLY when the already defined member data are edited. If the member data are being assigned to a new member, this item is not accessible.

Longitudinal reinforcement

Try to reduce length of bars

If OFF, the program uses only bars that extent along the whole length of the beam.

If ON, some bars may be shortened if the unity check is satisfied without them.

 

Maximal number of bigger diameters than the default

Defines how many different (bigger) diameters of the reinforcement can be used for the optimisation. Let us assume that the default diameter specified in the Design default tab is 10mm.

If this parameter is set to 2, the program can use diameters 10, 12 (i.e. +1 item in the manufacturing programme) and 14 (i.e. +2 item in the manufacturing programme) for the design.

 

Do not use "Neighbouring" bars

Some standards recommend that "neighbouring" profiles from the manufacturing programme should not be used in one beam (in order to avoid unintentional interchange of the profiles).

Let us assume that the default diameter specified in the Design default tab is 10 mm. Further assume that Maximal number of bigger diameters than the default is set to 2.

If this option is ON, the following bars can be inserted into the beam: (i) either 10 mm, (ii) or 12 mm, (iii) or 14 mm, (iv) or 10 mm and 14 mm can be combined together. 10 mm and 12 mm are not permitted to be combined in one beam.

 

Stirrups

Minimal stirrups distance

Specifies the minimal distance between stirrups measured from the centre of a bar to the centre of an adjacent bar.

 

Stirrups step

Defines the step for the reduction of the distance between two adjacent stirrups. This insures that the distance between stirrups is always a "rounded" number – e.g. 200 mm, then 250 mm, then 300 mm, etc. (and not e.g. 200, 246 mm, 298 mm, etc.).

 

Symmetrical stirrups parts

This parameter may enforce that the stirrup part are symmetrical along the length of the beam.

 

Member

(informative only)

Shows the name of the beam where the member data are assigned to.
The procedure to assign the member data

  1. Open service Concrete Advanced.

  2. Select branch Automatic member reinforcement design.

  3. Double-click function Member data.

  4. Select the beam where the new member data are to be assigned.

  5. Adjust the required parameters (see above).

  6. Confirm with [OK].
