**Creation method**

There are different creation methods. The user can decide out of these 7 options.

The default option is “By exact spacing value with flexible first and last space”.

The rebar group offers all these settings already so the values are just passed to the rebar group.

Creation method | Definition |
---|---|

By exact spacing value with flexible first space | Creates fixed, equal spaces between the bars. The first space adjusts to even out bar distribution. Enter the spacing value in the Exact spacing value field. 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 | Same as the first option, but the last space adjusts to even out bar distribution. |

By exact spacing value with flexible middle space | Same as the first option, but 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 | Same as the first option, but both the first and last spaces adjust to even out bar distribution. |

By exact spacings | Distributes the bars using the information you specify in the Exact spacing values field, so you can enter every spacing value manually. Use the multiplication character to repeat spacings, e.g. 5*200, to create five spaces of 200. |

Equal distribution by number of reinforcing bars | Tekla Structures determines the spacing value based on the fixed number of bars. Enter the number in the Number of reinforcing bars field. |

Equal distribution by target spacing value | Tekla Structures aims the spacing value as closely as possible at the value in the Target spacing value field and determines the number of bars compatibly. |

**U Bar dimensions**

The user can set the cover thickness for the side of the U bar and also the length of the U bar.

All other dimensions are calculated by the tool.
