API 650 10th Ed, Addendum 4 Seismic Loads
(OP)
I have calculated the seismic loads using Appendix E (Addendum 4) for a series of tall small diameter tanks. The overturning moment Ms is supposed to be used for foundation design. This number is based on allowable stress design (ASD). How do use this number with the load combinations?
This addendum is compatible with ASCE 7-05. Should I multiply Ms by 0.7 for the working stress concrete and foundation design or use the straight value for Ms?
