I want to design a shallow foundation for tower with circular base most probably it is a matt kind of foundation but I am confused whether to design as a concentrated load on the footing or a Continuous footing cause the loading will be acted in a circular pattern on the raft. The Dia = 20m...
What should be main controlling factors that should be taken in account while deciding the depth where you want to place your shallow foundation ?
How should I decide where I should put the foundation ?
What is the frost penetration depth in Italy. Most precisely I want the frost depth in Pisa. Any data for with or without reference will be helpful.
I found that it usually ranges from 1.5' to 3' in Pisa but I am not sure cause I don't have a strong reference on it.
Thanks
