"Design Placing Region" context toolbar

Tools: Design

The Design Placing Region context toolbar provides the following settings: The parameters that are actually available to you depend on the slab type selected.
If you want to change the support conditions, click the side of the slab.

Match panel widths and fixed points

You can use the panel arrangement of a placement already defined. This applies to all slab types with the exception of the BubbleDeck and Cobiax types. The panel widths that can be inserted in their entirety in the new placing region will then be used.

Depending on the setting in the input options, Allplan produces continuous rows of balls in span or transverse direction of the panel for slabs of the BubbleDeck and Cobiax type.

• Width: After you have selected the region whose panel arrangement and thus ball arrangement you want to match, Allplan uses the joints of this region as mandatory points. As a result, continuous rows of balls in span direction of the panel are created in neighboring fields so that the reinforcement at the top can be placed later.
• Ball spacing: After you have selected the region whose ball arrangement you want to match, the dialog line displays the ball displacement required in the longitudinal panel direction. Once you have confirmed the value, the start point of the ball arrangement will be moved by the dimension entered and the balls will be moved accordingly and installed. As a result, continuous rows of balls in transverse direction of the panel are created in neighboring fields so that the reinforcement at the top can be placed later.

Note: You can only copy the arrangement of a single placing region at any one time. For example, if there are two placing regions that are below each other and an adjacent region that is offset, it is normally not possible to find a ball arrangement in the longitudinal direction that produces continuous rows of balls in all three placing regions.

Place Standard Panels

Click this button if the current placing region is to be divided into standard panels.

Place Half Panels

Click this button if the current placing region is to be divided into half panels.

Vary Panel Width

Note: In the case of a Suspended Brick Slab design mode slab for which the Manage girder and brick rows separately option is selected on the General tab in the Panel Type Catalog, the panel width cannot be varied. The Vary panel width option is then deactivated.

Select this button, go to the input options to enter the Panel widths or Number of panels for the panel details and specify the required widths or numbers of panels.

With regard to the panel widths, you can enter any width; the program displays the residual width of the placement field.

For the number of panels, the number of panels to be created is selected. You can only enter values here that are in between the minimum and maximum possible number of panels determined using the settings for the Standard panel width and the Minimum width of fitted panel. Panels of the same width are then created.
Note: If you have defined fixed points, each one will be considered individually by way of an area limited by one or two fixed point(s).

Mirror Placement

Click this button if you want to mirror the current panel arrangement.

Consider Cranes

If you defined one or more cranes and crane locations by using the Crane Location tool before starting element design, select to include the crane parameters in the calculations of the individual panels.

Set fixed points for element division and/or support separation

When you click this button, you can place a fixed point for Element division or Support separation by clicking the corresponding button in the input options. This point is saved with the placing region and retained even if you modify the slab span later. Whether you modify the placement field manually or automatically is irrelevant. You can enter several division points in a field. Note that the Set fixed points for element division or support separation tool remains active after you have entered the first point so that you can place more points one after the other. When you close the tool, the program calculates the design again.

Note: If you do not place the fixed point for support separation exactly on the support line, it is automatically projected on this line. If it is too far from the support, the program displays a message to tell you that the symbol will not be created. You can use Stretch Entities to move the point for support separation. The design (bending shape, bar projection and so on) adapts accordingly.

Delete fixed points for element division and/or support separation

Click this button to delete a fixed point for element division. Note that the Delete fixed points for element division or support separation tool remains active after you have deleted the first point so that you can delete more points one after the other. When you close the tool, the program calculates the design again.

Lock support at left or Start design with ...

You cannot lock the support at the moment.
For suspended brick slabs, you can click the button to specify whether to Start design with girders or with bricks.
If you have selected the Manage girder and brick rows separately option on the General tab in the Panel Type Catalog for the Suspended Brick Slab and configured a Subpressure brick for the selected panel type, you can then choose from the two additional Vacuum panel by girder und Vacuum panel options.

Lock support at right or End design with fitted piece Fitted piece ...

You cannot lock the support at the moment.
For suspended brick slabs, you can click the button to select the fitted piece (in-situ concrete), fitted piece (bricks) or fitted piece (girders) options for the end of the design. The options that are actually available to you depend on the width entered for the placing region and the option selected for the start of the design.

Joint

This creates a joint between the panels. The unit is equivalent to the setting in the Options, Desktop environment page, General area.

Reinforcement parameters (not available for prestressed hollow core elements)

Click this button to define the reinforcement parameters of the basic reinforcement.

Maximum element weight (half floors and concrete slabs only)

You can change the initial value for the maximum element weight if the maximum element weight specified in the design and support parameters is not equal to 0.0, 99.0, or 999.9.

If standard panels cause the maximum element weight to be exceeded, the program will generate half panels (as with cranes). If the maximum element weight cannot be met even when half panels are used, the panel widths will be reduced incrementally by a fixed value of 5 cm until the maximum element weight is maintained.
Each panel is checked individually. Thus, standard panels can also be created after half panels.

Combine half/fitted panels while taking the max. weight into account (half floors and concrete slabs only)

You can influence the composition of half panels and fitted panels if the design takes the maximum element weight into account and half panels are placed.

If this button is selected, the last half panel and the fitted panel or the two fitted panels are combined into one panel if the maximum element weight is not exceeded.

Mark number

You can see the mark number for the next slab element or roof element. The program usually proposes the next available number that follows the highest number already used in the active drawing files.
Here, you can influence the way mark numbers are assigned. For example, you can configure the program to begin with 101. The greatest possible mark number is 99999999. If you have selected Identical for the assignment of mark numbers in the configurations, identical elements are given the same mark number.

Note: If Zero is set for the assignment of mark numbers in the Configuration Menu, you cannot make any entries.

span direction

You can change the direction of span in an active placing region. The program calculates the shorter distance.
Click to define the span direction by entering two points.
Click in the box and enter a value for the span direction.

Span direction +90 degrees

You can change the direction of span in the active placing region by +90 degrees.

or Required bar cross-section asx-bottom / asy-bottom
or Required bar cross-section asx-top / asy-top

Depending on the prompts you defined for structural analyses in the configurations, you can enter the required as-value for the slab span or roof span. The program selects a reinforcement type from your catalog. If the prompt for the reinforcement type is active, you can change the value the program proposes for the reinforcement type.
If Prompt required bar cross-section is off but Prompt reinforcement type is on in the configuration, you can select the reinforcement type. For prestressed hollow core elements and TT slabs, you can only enter the reinforcement type. For BubbleDeck, brick slabs and concrete brick slabs, you can define only the required reinforcement in the bottom layer.

Note: If the Longitudinal Bars or Cross Bars tab in the Basic Reinforcement Parameters contains a setting that controls how to calculate reinforcement (for example, the Lock Diameter or Lock Offset check box is selected; diameters and offsets are specified), you can see red exclamation points next to the icons of the boxes.
