Thanks for your helpful comments above - I am now finalising design and preparing drawings for construction, confident that the additional foundation costs incurred by this assumption are justifiable.
The following is a Thread I posted in "foundation engineering" - I got two repiles effectively agreeing with my concern. Any comments from Seismic Experts here?
I have two large stoves approx 30m tall, 7.7m diameter, 10m apart weighing about 1700tonnes each. Seismic forces will govern...
I have two large stoves approx 30m tall, 7.7m diameter, 10m apart weighing about 1700tonnes each. Seismic forces will govern strength design of an (unfortunately) combined foundation.
Obtaining seismic forces is pretty straightforward but the question is ----
In the event of an earthquake, can...
