Distribute bars in a reinforcing bar group
You can select how reinforcing bars are distributed in a bar group by modifying the bar spacings.
To modify the spacings of bars in a reinforcing bar group, do one of the following:
To  Do this 

Modify the spacings using direct modification 

Modify the spacings using the Rebar group properties 

Spacing options in the Creation method list:
Option  Description  Example 

Equal distribution by number of reinforcing bars 
Enter the number of reinforcing bars. Tekla Structures divides the available distance by the number of bars. Enter the number of bars in the Number of reinforcing bars box. 

Equal distribution by target spacing value 
Enter a spacing value. Tekla Structures aims the spacing value as close as possible to the value in the Target spacing value box. 

By exact spacing value with flexible first 
Enter the spacing value in the Exact spacing value box. Creates fixed, regular spaces between the bars. The first space adjusts to even out the bar distribution. If the first space is less than 10% of the exact spacing value, Tekla Structures removes one bar. 

By exact spacing value with flexible last space 
Enter the spacing value in the Exact spacing value box. Creates fixed, regular spaces between the bars. The last space adjusts to even out bar distribution. 

By exact spacing value with flexible middle space 
Enter the spacing value in the Exact spacing value box. Creates fixed, regular spaces between the bars. The middle space adjusts to even out bar distribution. If there are an odd number of bars (two middle spaces), the other middle space adjusts to even out bar distribution. 

By exact spacing value with flexible first and last space 
Enter the spacing value in the Exact spacing value box. Creates fixed, regular spaces between the bars. Both the first and last spaces adjust to even out bar distribution. 

By exact spacings 
Enter the spacing values manually in the Exact spacing values box. Use multiplication to repeat spacings, for example, 5*200 to create five spaces of 200.
