Corbel reinforcement (81)

Corbel reinforcement (81) creates reinforcement for one or two corbels in a concrete column. The two corbels must have the same top level, thickness, and horizontal location.

Objects created

Main bars
Stirrups
Additional bars

Use for


Situation	Description
	Two corbels, beveled and rounded, with the same top level, thickness, and horizontal location. Two additional bars crossing each other.
	One straight corbel. One additional bar.

Limitations

Do not use Corbel reinforcement (81) for two very different corbels.

Before you start

Create the concrete column and beams.
Create the corbels. Use Corbel connection (14) or a seating connection to create the corbels.

Selection order

Select the main part (concrete column).
Select the secondary parts (one or more corbels).
Click the middle mouse button to create the reinforcement.

Main bars tab

Use the Main bars tab to control the main bar length, concrete cover thickness, reinforcing bar spacing, and reinforcing bar properties.


	Description
1	Main bar length.
2	Distance from the concrete surface to the main bar.


Option	Description
Grade	Strength of the steel used in the reinforcing bars.
Size	Diameter of the reinforcing bar.
Name	Define a name for the main bars. Tekla Structures uses the name in drawings and reports.
Class	Use Class to group reinforcement. For example, you can display reinforcement of different classes in different colors.
Prefix	Prefix for the part position number.
Start number	Start number for the part position number.

Follow shape

This setting also affects the transverse stirrups.


Option	Description
	Inclined The last rebar segment follows the inclined corbel edge.
	Horizontal The last rebar segment is created horizontally.

Cover thickness


	Description
1	Concrete cover thickness.
2	Number of bars in the reinforcement.
3	Space between the reinforcing bars.

Stirrups/Transverse stirrups/Diagonal stirrups tab

Use the Stirrups, Transverse stirrups and Diagonal stirrups tabs to control the stirrup creation, stirrup type, concrete cover thickness, reinforcing bar spacing and properties.

Stirrups

Define the distance from the concrete surface to the stirrups.


Option	Option	Option

Concrete cover thickness

Define the concrete cover thickness. You can select that the concrete cover is the same at each side.


Option	Option	Option


Option	Description
Number of bars	Define the number of bars in the reinforcement.
Spacing values	Define the space between the reinforcing bars.
Transverse stirrups in column	Select whether the column is reinforced with transverse stirrups.
Name	Define a name for the stirrups. Tekla Structures uses the name in drawings and reports.
Size	Diameter of the reinforcing bar.
Grade	Strength of the steel used in the reinforcing bars.
Class	Use Class to group reinforcement. For example, you can display reinforcement of different classes in different colors.
Prefix	Prefix for the part position number.
Start number	Start number for the part position number.

Stirrup type


Option	Description
	The stirrup consists of a bent single reinforcing bar. Define the hook length. The default values (for the standard 90 degree stirrup hook) are read from the rebar_database.inp file. Select a suitable overlap position for this stirrup type.
	The stirrup consist of two overlapping U bars that face each other. Define minimum and maximum overlapping length.
	The stirrup consists of two overlapping U bars. Define minimum and maximum overlapping length.
	The transverse stirrup is one open U-bar.

Additional bars tab

Use the Additional bars tab to control the creation of additional bars in corbels, concrete cover thickness, and additional bar properties.

Additional bars


Option	Description
	No additional bars.
	One additional bar.
	Two additional bars parallel to each other.
	Two additional bars crossing each other.
	Two pairs of additional bars crossing each other.

Stirrups and cover thickness

Define the distance from the concrete surface to the stirrups and the additional bar dimension.

Define the concrete cover thickness.


Option	Description
Grade	Strength of the steel used in the reinforcing bars.
Size	Diameter of the reinforcing bar.
Name	Define a name for the additional bars. Tekla Structures uses the name in drawings and reports.
Class	Use Class to group reinforcement. For example, you can display reinforcement of different classes in different colors.
Prefix	Prefix for the part position number.
Start number	Start number for the part position number.
