Max considered earthquake response acceleration to Design acceleratio
(OP)
In codes, SDS=2/3*SMS.
SMS is from Fa*Ss, and Ss is from the map.
but where is the 2/3 from?
Does anybody know where is the 2/3 from?
I am not sure if the 2/3 is used for 500 year return period since the map is for 2,500 year return?
Thanks.

RE: Max considered earthquake response acceleration to Design acceleratio
It essentially lets you take a 150% overstress in the applied seismic accelerations (2/3 = 100/150).
Hope this explains it!
