what if I design wall for fixed support at bottom.
I think moment from wall will not be transfered to base slab decause the joint between slab and wall is restrained from rotation. As it will tend to rotate soil pressure below slab and behind wall (passive)will increase which will prevent joint from rotation.As long as soil pressure is below bearing capacity no or very little curvature will develope in base slab.So external moment from wall will resisted by forces developed in soil.
please comment on this explanation.
Secondly i have not read in any book talking about moments in base slab when tank is fully filled .
