Earthquake design categories
Earthquake design categories
(OP)
AS3600 (including the latest draft I've seen) and AS4100 give earthquake detailing requirements for earthquake detail categories A to E. They were defined in AS1170.4-1993 but are no longer defined in AS1170.4-2007 so you are in a bit of a black hole trying to be consistent.
Does anyone know if this is going to be fixed or if there is any commentaries?

The S factor which multiplied by a Earthquake Co-efficient C would give you an elastic response spectrum.
These factors S and C have been replaced by a new individual factor Ch(T) which has a different elastic response spectrum curve for each site class.
What we have found ourselves doing for Earthquake designs using AS5100 is to take the hazard factor Z from AS1170.4-2007 and the site factor S from AS1170.4-1993 for the determination of the Earthquake Design Category.
