The Slab Corner - Reinforcement option defines reinforcement of an RC slab corner. Select the option from:
- Menu: Reinforcement > Structure elements - reinforcement > Slab corner
- Ribbon: ASD - Structure elements > Structure elements - reinforcement > Slab corner
- Toolbar: Structure elements - reinforcement > Slab corner
.
The following dialog displays:
The upper part of the dialog provides parameters for selection of a reinforcement scheme. There are four types of reinforcement schemes for slab corners:
-
-
-
.
The following reinforcement parameters should be specified:
- Reinforcement cover
- Steel grade.
The location of the corner reinforcement (top or bottom) should also be specified.
The middle part of the dialog includes parameters used to define the Dimensions field as follows:
- Dimensions of a region covered by corner reinforcement (specify two dimensions in the directions perpendicular to each other, and one dimension if the first symmetrical scheme is chosen)
- Reinforcing bar parameters (depending on the reinforcement scheme: for one or for two directions): reinforcing bar diameter and bar spacing (in the every field).
You can also define a type of reinforcing bar ends:
straight bars 
first bend type; value of the parameter a should be specified 
second bend type; values of the parameters a and b should be specified.
The example of reinforcement of slab corners, with the use of all the four reinforcement schemes (each scheme type in a different corner of the slab), is shown below.
Units used to define the corner geometry and reinforcement are set in the Job preferences dialog.
The bottom of the dialog includes a selection lists that define a hierarchy of defined projects and templates; the following rules apply while creating the hierarchy:
- A project is a component superior to a group in the hierarchy
- Several different groups may be defined in a project
- Each group may include many templates.
Such hierarchy makes it easier to manage structure elements included in a project. It is also simpler to copy a project between two users (computers used by users), by copying a whole folder with the project name for the entire project hierarchy with all groups and templates.
You can define an arbitrary hierarchy; the following hierarchy can be used as an example:
- Project - High-rise building
- Group - Story 1
- Template - Slab corner 01.
The Template list includes user-defined templates (schemes) of slab corners and their reinforcement. After defining the geometry and reinforcement of a slab corner, it is possible to save these settings by specifying a name in the Template field and clicking the Save button (Note: a template is saved in a selected group and a selected project). After defining the slab corner reinforcement and selecting the name of a saved template (in a selected project and a selected group), all parameters in the dialog are set exactly as they are defined in the template.
To open a template saved in a selected project and a selected group, click Load. To delete a selected template assigned to a selected project and a selected group, click Delete.
Templates saved in the macros for formworks of structure elements are available and can be loaded to the corresponding reinforcement macros. Once such a template is loaded, the Geometrytab sets parameters of the structure element geometry saved in the template.
The following buttons are located at the bottom of the dialog:
- Preview - Click to display the defined slab corner and reinforcement
- Back < / Next > - Click to open the dialog on the previous / next tab
- Insert - Click to place the defined slab corner and reinforcement in a drawing. The number of reinforcement positions and locations for the defined slab corner in a drawing should be defined; together with a drawing of a slab corner. A reinforcement table compliant with the settings specifed in the Job preferences dialog is inserted.
