STAAD does not have NZS 1170.5 in its Seismic Codes. Users in ANZ uses custom spectrum and factored it up to match the base shear.
Adding this code will help the users in ANZ work directly with the NZ code and thus speed up their productivity.
Users in ANZ have started to use STAAD and having their code will increase the usage. They already use the physical member design and this addition will boost the usage more.

Thank you for posting this idea. We do have a backlog request for adding the seismic loading to the AS/NZS 1170.4, Structural design actions Earthquake actions in Australia. Did you mean that?
