Anchorage length and overlap length

In accordance with 8.4.3 of DIN EN 1992-1-1 effective January 2011, the basic value of anchorage length is calculated using the existing value for steel stress in conjunction with the ultimate limit state of the bar. When calculating the basic value of anchorage length, the program now takes into account the existing reinforcement ratio for the EN standard as well as the BS EN, TS 500, NEN EN and NTC standards.

For the DIN EN standard, on the other hand, the basic value of anchorage length is initially calculated for full capacity and the existing reinforcement ratio is not taken into account until the anchorage length and overlap length are calculated. In comparison with the other Euronorms, this results in greater minimum lengths.

During revision we also made some corrections to length calculations in the Brazilian standard.
