It checks bond, anchorage length and the concrete edge conditions, and produces a full calculation report. It is free, needs no registration or installation, and has a Hebrew interface.

- Starter bars — connecting new columns and walls to an existing element.
- Slab and wall extensions — continuing an existing element in new concrete.
- Bond check — the bond capacity between the bar and the concrete.
- Anchorage length and edges — the required depth and the effect of the distance to the concrete edge.
- Full calculation report — to attach to a submission.
When you need it
Almost every extension, renovation or repair of an existing structure has to join new concrete to old. ARS answers the practical question — whether the bond, the anchorage length and the concrete edge conditions work for the planned bars — with a calculation you can submit.
