Column Reinforcing - Ties tab

Used to create tie zones — each with different spacing or bar sizes — and tie types within each zone.

As many different types of ties as necessary can be entered, with each new tie saved as a line in the detail table. The ties are defined by clicking the bars in the cross section around which the tie is placed. Each Tie Zone is used to create a separate spacing or tie arrangement along the height of the column. Each tie within a zone is used to specify an individual tie at each spacing location along the zone.

  • Start / End (Offsets) – Sets distance from the start of the zone to the first tie, and from the end of the zone to the last tie, respectively.
