Elevated Tank Support - API 650 App E or ASCE 7-05 Chapter 15
(OP)
API 650 Appendix E Seismic Design seems to be devoted to flat bottom tanks supported at grade. Should I be using ASCE 7-05 Eq. 15.4-5 to generate the seismic shear load to design the tank support structure and foundation.
The tank is 21' in diameter and 20' high and it is supported on a steel grillage about 6' above grade. The steel is supported on a series of concrete walls and footings.

IMHO, you have just crossed into an area where a specialist may be required to perform a more detailed seismic analysis.
There are plenty of engineering consulting firms with lots of detailed analysis tools and experience in the nuclear power industry that can help you.
