'Reinforcement Parameters' dialog box

By entering a search criterion, you can filter the reinforcement types if you are reinforcing in accordance with 'as-req'. The program only uses reinforcement types that comply with the search criterion specified.

You can select the reinforcement type manually or configure Allplan to automatically determine a type based on the required as-value.

(Check boxes) You can exclude reinforcement elements (as opposed to the settings in the catalog).

You can select the ‘attached reinforcement’ type here. Attached reinforcement can be created as any reinforcement or based on reinforcement type.
When attached reinforcement is enabled, you can make additional settings on the Att. Reinf. tab.

You can check and alter the steel grades that are preset in the configurations and saved with the placement and/or element. The steel grade for girders is taken from the girder catalog and cannot be altered.
You can only enter the steel grade for reinforcing meshes and bars if the check box of the relevant reinforcement element is selected on the General tab.

You can only enter something here if you have selected the use of girders on the General tab.

You can specify how girders are to be calculated. Various predefined options are available. You can change this setting for each design calculation process. In addition to the options provided for double walls, girders can also be entered manually. In this case, you can select a lattice girder directly in the dialog box for the wall parameters.

Options for calculating girders

Option 1: the girder height is calculated from the wall thickness minus the concrete covers and twice the value of the bar thickness entered. The tolerances specified are taken into account.
Using this option, you can control how the height is calculated, as the girder heights specified in the girder catalog often differ from the height between the bottom boom and the top boom.

Option 2: the girder height is calculated from the wall thickness minus the concrete covers and the actual diameters of the first cross bars. If the cross bars are not in the first layer, all the diameters of the outer bars are also considered. The tolerances specified are taken into account.

Option 3: the girder height is calculated from the wall thickness minus the value specified. The program adjusts the concrete cover, so that the combination of possible spacers and calculated cross bars is as close as possible to the value specified. It is essential that the entire reinforcement is defined before it is created. Otherwise, the concrete cover cannot be calculated correctly. The tolerances specified are taken into account.

Note: You can define the bar thickness (for option 1), the value to be subtracted (for option 3) and the tolerances in the configuration entry for lattice girders of the double wall calculation.

(Check box) You can specify whether lattice girders are rotated before they are placed. Girders are rotated by 180° about their longitudinal axis.
This setting is only available for attached reinforcement and affects the number of locked zones.

(Check box) You can set whether or not the bottom and top booms of the lattice girders are taken into account in the structural calculations of double walls.

Shortening of lattice girders at top/bottom (for example, to account for an insulating strip).

Distribution based on factory data: the girder spacings used are from the girder spacing catalog.

Lock spacing to: the program uses the girder spacings entered here when reinforcing rather than those in the spacing catalog.

Lock edge offset to: the program uses the girder edge offsets entered here rather than those in the spacing catalog.

Lock spacing to .... and lock edge offset to: the program uses the girder spacings and edge offsets entered here when reinforcing rather than those in the spacing catalog.

Variable spacing entry: if this switch is selected, the program prompts for each spacing when reinforcing.

You can only enter something here if the use of reinforcing bars is selected on the General tab.

(Check box) If this switch is selected, then the diameters selected below are used for the longitudinal bars. You should note though that the bar layers from the reinforcement types catalog do not apply to this. The program calculates the bar spacing from the required as-Value entered.

(Check box) If this switch is selected, then the offsets selected below are used for the longitudinal bars. You should note though that the bar layers from the reinforcement types catalog do not apply to this. The program calculates the bar diameter from the required as-value entered.

If you want to deal with single bar layers only, irrespective of whether diameters and/or spacings are produced from the type catalog, select the desired value from the boxes below without selecting the check box.

You can only enter something here if attached reinforcement is selected on the General tab.

When this check box is selected, the maximum possible number of longitudinal bars is shortened by the vA (shortening value - start) and vE (shortening value - end) values; however, at least 50% of the bar cross-sectional area (as_req) are used up to the support. The shortening values vA and vE are based on the start and end of the bar.

You can specify the following values that are taken into account when the program calculates the bars of attached reinforcement:

So that you do not have to enter the values from scratch each time, the program always proposes the values you entered last.

Specify whether shortening is calculated as a percentage or based on fixed values.

Enter the shortening percentage provided you have set the 'Calculate shortening' option to 'percentage'. The shortening values for the start and end are calculated again.

You can enter something here when 'calculate shortening' is set to fixed. The percentage is calculated again.

If this check box is selected, then the program attempts to alternately shorten the longitudinal bars at the start and end.
