Is the correct Soil Factor per EN1998-1 being used?
There was an French rule from 2010-10-04 where the values of S (Soil factor) are different from the EUROCODE
EN 1998-1:2004+A1:2013:
S = 1.8 for ground Type D
S = 1.6 for ground Type E
French Rule 2010-10-04:
S = 1.6 for ground Type D
S = 1.8 for ground Type E
AutoPIPE Vessel conforms to the Eurocode (EN 1998-1:2004+A1:2013).
The user can enter a user-defined normalized spectrum to get different values of S (S is equal to Ra in the Dialog).
