Siesmic Zone 8
Siesmic Zone 8
(OP)
Can anyone tell me if a siesmic zone 8 exists in the United States? A co-worker insists that one exists but I don't think so. If one exists, can someone point me in the direction to obtain some information?
Thank you
Thank you

Presently there are Zones 1-4 with 4 being the zone of highest probable ground acceleration.
In other codes such as the AASHTO code for bridges, the zones are denoted as Seimsic Performance Categories (SPC) and are A, B, C, and D. In this case, D is the category of highest probable ground acceleration.

If your source tells you that its just like in the U.s., then they are mistaken as there is no zone 5 or equivalent in the UBC.
It must be an SA code of some sort - or they are simply mistaken.
