The design - including the static values - does only apply to the designated HALFEN product. The load bearing capacity of third party products, appearing to be
identical in construction, might differ. For this reason, the software provider does not extend warranty if external products are used.

Minimum bar length: lbar,min,x = 169.5 cm + l bd ; lbar,min,y = 264.7 cm + l bd ; l bd is the anchorage length
Minimum bar length was determined according to booklet 600 (2nd edition 2020).
Note: Due to other verifications, different minimum bar length can be decisive.
Bar length calculated without the required design anchorage length at the free edge. The anchorage length at the free
edge has to be determined separately.
