Create a curved reinforcing bar group
You can reinforce curved segments in a concrete beam or a curved wallplate that represents a structure such as a wall or roof panel
In Tekla Structures, a panel is created by picking two or more points.
In cast-in-place concrete the term wall refers to a concept similar to panel.
- On the Concrete tab, click Rebar and select Curved bar group.
If you need to modify the properties before you create the reinforcement, hold down Shift and click the Curved bar group command to open the Reinforcing Bar Properties dialog box.
- Select the part to reinforce.
Tekla Structures attaches the bar group to this part.
- Pick three points on an arc to define the curve.
- Pick two points to indicate the distribution direction of the bars.
Tekla Structures creates a group of curved reinforcing bars.
- If you want to change the curved reinforcing bar groupgroup of reinforcing bars that are side by side and have identical properties, except the possible variation in bar lengths
- Double-click the curved reinforcing bar group to open the Reinforcing Bar Properties dialog box.
- Modify the properties.
- Click Modify.
Curved reinforcing bar group properties
Use the Reinforcing Bar Properties dialog box to view and modify the properties of curved reinforcing barreinforcement that represents a steel bar used to reinforce a concrete structure
The steel bars are usually ribbed and they are used to increase the tensile strength of concrete.
groups. The file name extension of the properties file is .rcu.
|Bar prefix and start number||Mark series of the reinforcing bar.|
User-definable name of the bar.
Tekla Structures uses bar names in reports and drawing lists, and to identify bars of the same type.
Diameter of the bar.
Depending on the environment, the nominal diameter of the bar, or a mark that defines the diameter.
Size-grade-radius combinations are predefined in the reinforcing bar catalog. Click the Select button to open the Select Reinforcing Bar dialog box. The dialog box shows the available bar sizes for the chosen grade. You can also select whether the bar is a main bar or a stirrup or tie.
The rebar_database.inp file contains the predefined reinforcing bar catalog entries.
Steel grade of the bar.
Internal radius of the bends in the bar.
You can enter a separate value for each bar bend. Separate the values with spaces.
Bending radius complies with the design code you are using. Main bars, stirrups, ties, and hooks usually have their own minimum internal bending radii, which are proportional to the diameter of the reinforcing bar. The actual bending radius is normally chosen to suit the size of the mandrels on the bar-bending machine.
Used to group reinforcement.
For example, you can display bars of different classes in different colors.
|Hooks Shape||Shape of the hook.||
The rebar_database.inp file contains the predefined minimum bending radius and minimum hook length for all standard hooks.
|Hooks Angle||Angle of a custom hook|
|Hooks Radius||Internal bending radius of a standard hook or custom hook.|
|Hooks Length||Length of the straight part of a standard or custom hook.|
|Cover thickness on plane||Distances from the part surfaces to the bar on the same plane as the bar.||See Define the reinforcement cover thickness.|
|Cover thickness from plane||Distance from the part surface to the bar, or to the bar end, perpendicular to the bar plane.|
|Start||Concrete cover thickness or leg length at the first end of the bar.|
|End||Concrete cover thickness or leg length at the second end of the bar.|
You can create user-defined attributes to add information about reinforcement. Attributes can consist of numbers, text, or lists.
You can use the values of user-defined attributes in reports and drawings.
You can also change the name of the fields, and add new ones, by editing the objects.inp file. See User-defined attributes (UDAs) in the objects.inp file.
