STAAD.Pro Help

Norwegian Codes - Steel Design per NS 3472 / NPD

STAAD.Pro performs a stability check on aluminum alloys according to buckling curve in ECCS (European recommendation for aluminum ally structures 1978). It is possible to select heat-treated or non heat-treated alloy from the parameter list in the STAAD.Pro input file.

For heat-treated use CY = CZ = 0.1590, and for non heat-treated use CY = CZ = 0.2420.

Tracks 1.0 and 9.0 print buckling curve H for heat-treated, and buckling curve N for non neat-treated. The yield check is the same as for steel.
