Add hooks to reinforcing bars

You can add hooks to the ends of reinforcing bars for anchoring purposes.

Note:

Hooks are intended to be used only for anchoring purposes. Do not use hooks as a method to model other 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.

For example, reinforcement and surface treatment automatically adapt to the changes made to the part they are linked with.

, and in bar bending shape recognition.

To add hooks to reinforcing bars, do one of the following:

To Do this

Add hooks using direct modification

  1. Ensure that theDirect modification switch is active.

  2. Select a single reinforcing bar or a reinforcing bar group.

  3. Click the start or end point of the reinforcing bar.

    A toolbar for hook properties appears.

  4. Select the desired shape for the hook.

  5. If you select Custom hook , enter the angle, radius, and length for the hook. Click.

Add hooks using the Reinforcing Bar Properties dialog box

  1. Select a single reinforcing bar or a reinforcing bar group.

  2. Double-click the reinforcement to open the Reinforcing Bar Properties dialog box.

  3. Select a hook type from the Shape list.

  4. If you select Custom hook , enter the angle, radius and length for the hook.

  5. Click Modify.

Add hooks to rebar sets using end detail modifiers

See Modify a rebar set locally using modifiers.

For custom hooks you need to enter the hook information:

Option Description

Angle

Enter a value between -180 and +180 degrees.

  1. Angle

  2. Length

  3. Radius

Radius

Enter the internal bending radius of the hook.

Use the same radius for the hook and for the reinforcing bar. If the hook and the reinforcing bar have different radiuses, Tekla Structures does not recognize the shape of the bar.

Length

Enter the length of the straight part.

If the length is set to zero, no hooks are created.

Hook examples

  Description
1 Standard 90-degree hook
2 Standard 135-degree hook
3 Standard 180-degree hook
4 Custom hook

If you select a standard hook, the Angle , Radius , and Length use predefined dimensions.

The rebar_database.inp file contains the predefined minimum bending radius and minimum hook length for all standard hooks.
