A pour unitentity that combines together a pour object and the other building objects that need to be in place before cast-in-place concrete can be poured

The needed building objects can be reinforcement and embeds, for example.

is a management unit for cast-in-place concretecast unit type where the concrete is formed, poured, and cured in its final position

. The pour unit consists of a pour objectbuilding object that is formed of one or more cast-in-place concrete parts, or parts of cast-in-place concrete parts

The cast-in-place concrete parts are merged into one pour object if they have the same material grade and pour phase, and if they touch each other. Pour objects are visible in pour view.

and all related reinforcement, embeds, and other objects that need to be in place before concrete can be poured on the building site.

For each pour object in the model, there is a corresponding pour unit to which the pour object belongs. You can automatically add other objects to pour units by using the Calculate pour units command. You can also modify the pour units manually.

The following model objects can be added to pour units:

• Reinforcement, such as single reinforcing bars, bar groups, reinforcement meshes and strands
• Assemblies (for example, embeds)
• Sub-assemblies (for example, embeds in cast-in-place cast units)
• Bolts (for example, anchor bolts and shear studs)
• Precast cast units
• Surfaces added to the pour object

Note that some model objects such as parts and welds cannot be directly added to a pour unit. Instead, these objects are indirectly linked to the pour unit through the assemblies and cast units they belong to.

One model objectobject that is represented in a model

A model object is either created in a model or imported into it.

can be included in only one pour unit at a time.

You can have Tekla Structures detect which objects form pour units and automatically add the objects to pour units.

You can visually check which objects are included in a pour unit. You can also use the Inquire tool to get information about the pour unit and the objects in it.

1. Ensure that you are using a pour view. If not, on the Concrete tab, click Pour view to show the pour objects.
2. Ensure that theSelect assemblies selection switch is active.
3. Click a pour object to select its pour unit.
   

   A magenta box indicates the pour unit.

   

4. Right-click and select Inquire.
   

   Tekla Structures lists the objects in the pour unit and shows their properties in the Inquire object dialog box.

In addition to using the Calculate pour units command, you can manually add objects to pour units.

1. Ensure that you are using a pour view. If not, on the Concrete tab, click Pour view to show the pour objects.
2. Select the objects that you want to add to a pour unit.
   

   You can select reinforcement, assemblies, precast cast units, and bolts.

3. Right-click and select Pour > Add to pour unit.
4. Click a pour object to add the objects to the corresponding pour unit.

After using the Calculate pour units command, you can manually remove objects from pour units.

1. Select the object that you want to remove from a pour unit.
2. Right-click and select Pour > Remove from pour unit.

You can modify the pour unit properties in the same way as pour object propertiesproperties associated with an object type

Usually a single object property includes a default value that the user can modify.

, but using a different selection switchswitch used for controlling which object types can be selected

.

1. Ensure that you are using a pour view. If not, click Pour view on the Concrete tab to show the pour objects.
2. Ensure that theSelect assemblies selection switch is active.
3. Double-click the pour unit whose properties you want to modify.
4. In the property panecontrol element in Tekla Structures user interface in the form of a side pane window
   
   The property pane can be used to show and modify the properties of model objects.
   
   The property pane can be customized by using the property pane editor.
   
   , enter or modify the pour unit properties.
   

   For example, you can define the pour unit name and user-defined attributes.

5. Click Modify.
