Side left tab
Use the Side left tab to create and define the properties of the horizontal rebars on the left side.
The rebars which can be created are placed in longitudinal direction (similarly as the primary bars), but now the bends are created horizontally. The options on this tab (defining rebar shape, dimensions, number of bars, and rebar distribution) are similar to the options on the Primary bottom bars tab.
Examples of rebars which can be created with this tab:
Side right tab
Use the Side right tab to create and define the properties of the horizontal rebars on the right side.
This tab is similar to the Side left tab but the reference is the right side of the parts.
Stirrups tab
Use the Stirrups tab to define the dimensions of the stirrups in the first section of the concrete part.

Define the length of the left end extension. To define the length, select some other value than Default in End conditions left. |
|
Bend lengths right |
Define the length of the right end extension. To define the length, select some other value than Default in End conditions left. |
End conditions left/right
Define the end condition of the rebars on the left and right side.
Section B - Stirrup dimensions
Define a fixed distance from the bottom side of the concrete parts to the bottom side of the stirrup.
Note: This offset is
normative.
Define the offset, width, and height of the stirrup.

Stirrup rotation
You can define the rotation of the stirrups. There are four options and each option rotates the stirrup 90 degrees counterclockwise.
Stirrup spacing tab
Use the Stirrup spacing tab to define the distribution of the stirrups along the concrete part.
You can define six zones for the distribution. For each zone you can set a number of stirrups. The distance between the stirrups can be defined in two ways:
-
Fixed spacing between each stirrup.
-
Distance between outer stirrups.
Spacing is then calculated from this distance divided by the number of stirrups.

Stirrups 2 tab
Use the Stirrups 2 tab to define a second group of stirrups. The options on this tab are similar to the options on the Stirrups tab.
This tab can be used if the shape of the concrete part is not uniform. For example, if a part cut is applied, you may need different stirrups on that area.

Configuration tab
Use the Configuration tab to define the bending radius and rotation.
Bending radius
You can set the bending radius separately for the main reinforcing bars and the stirrups. You can also set the radius separately for the main bends and the hook-bends.

Option |
Description |
|---|---|
|
rebar_database.inp |
The bending radius is determined from a configuration file rebar_database.inp. This file is located in the profil folder. |
|
Relative to diameter |
The radius is calculated by multiplying the reinforcing bar diameter with the entered coefficient. |
|
Bending radius |
Use this option to use a fixed value for the bending radius. |
Rotation
Define the orientation of the complete rebar structure in the concrete part. There are four options and each option represents a 90 degree rotation.
