Calculating the anchorage length

Tool(s): FF Components

Click to open the dialog box for calculating the anchorage lengths. The program calculates the anchorage lengths for the current diameter and the selected steel and concrete grades based on the parameters you have defined.
The Diameter, Steel grade and Concrete grade parameters are displayed for information only and cannot be modified.

To define the anchorage length

1. Choose the Composite zone and enter a value for Req'd. As / Existing As.
2. Select the Compression bar option if you want the system to calculate the anchorage lengths for a compression bar.

   When this option is selected, the value you enter for the amount without longitudinal stagger and the type you select in the anchorage area do not have any effect on the anchorage lengths.

3. When the Compression bar option is not selected, enter a value for the Amount without longitudinal stagger and select a type in the anchorage area. Based on these settings, the program automatically calculates the Overlap length.

   The program displays the calculated values in the Selected area. Use the Round length to box to determine the round-off value for the bar lengths.

4. Click an anchorage length in the Selected area: The following options are available:
   • - interprets the anchorage length as the segment length. This is the same as entering a positive length.
   • - uses the anchorage length outside the formwork. This is the same as entering a negative length.
   • - uses the anchorage length inside the formwork. This is the same as entering a length and adding ”*”.
5. Click OK to confirm the settings.
