Tool(s): Extrude Bars Along Path + Modify Bars Extruded Along Path

You can define general parameters and parameters for transverse reinforcement and longitudinal reinforcement.

General

Profile rotation

Define how the bending shapes of transverse reinforcement will be placed in relation to the path.

• None: Allplan places the bending shapes with no rotation along the path in elevation and plan view.
• Default: Allplan places the bending shapes so that they are perpendicular to the path in elevation and plan view.
• Z-axis: Allplan places the bending shapes with no rotation in elevation. In plan view, on the other hand, the bending shapes are perpendicular to the path.

Eliminate break of path, Maximum angle of joint

When you select this check box, Allplan "breaks up" the placement at bends of the path where the angle is greater than the value entered. This results in discrete placing regions, which all get the same settings.

Concrete cover

Same concrete cover

When you select this check box, Allplan applies the same concrete cover to the start and end of each placing region. In this case, you only need to enter the concrete cover once.

If this check box is not selected, you can define the concrete cover individually for the start and end. These values apply to all placing regions.

Reinforcement

Component factor

You can enter a factor for placements that are displayed just once but that occur several times. This factor is only taken into account for the reinforcement management and the schema.

Layer factor

You can enter the number of the congruent bar layers placed one upon the other.

Transverse reinforcement

Spacing

You can define the spacing of transverse reinforcement along the path. Select a value in the list box or enter any value.

Region ...

You can create two regions with different spacing at the start and end of the placement. Define the length and spacing for each region. Allplan places the first or last bending shape of transverse reinforcement with the defined concrete cover in the first or last region respectively. The first bending shape of the other region follows at the offset specified for this region. Allplan places transverse reinforcement in the remaining region so that the reinforcement is centered.

To avoid excessive spacing in the areas where the regions meet, Allplan creates an additional bending shape of transverse reinforcement. This bending shape is outside the length you defined for the region.

Bar offset

You can enter a value for the offset between the bending shapes of transverse reinforcement. When you enter the value 0, Allplan creates congruent bending shapes. This makes it difficult to tell them apart.

Longitudinal reinforcement

Group

You can use and to toggle between the groups of longitudinal reinforcement. Allplan combines all bars with the same mark number to form a group. You can see the current group and the total number of groups.

After expanding the entry, you can define the following settings for each group.

Overlap at start, Overlap at end

After selecting this check box, you can enter any value for the overlap or have Allplan calculate this value.

Delivery

You can choose to supply the building site with straight or bent longitudinal bars. If you select straight bars although the building site requires bent bars, the bars will be bent on site. Consider the reference values for prebending circular reinforcement.

Depending on the diameter, bars used for circular reinforcement should be pre-bent up to the following radii. Consider the restoring force near the limits.

d=6 --> r=1.00 m

d=8 --> r=1.50 m

d=10 --> r=3.00 m

d=12 --> r=5.00 m

d=14 --> r=7.00 m

d=16 --> r=15.00 m

d=18 and larger: always pre-bend the bars!

Overlap length

You can enter any value for the overlap length or have Allplan calculate this value. If the bars of longitudinal reinforcement exceed the maximum bar length defined in the Options, Allplan creates placements of maximum length. If this results in different bar lengths for the group, Allplan creates a polygonal placement.

Bar, Starting length

You can use and to toggle between the bars of the current group. You can see the current bar and the total number of bars.
After expanding the entry, you can define the starting length for each bar, thus creating offset placements. If this results in different bar lengths for the group, Allplan creates a polygonal placement.
