I have design a manhole using plates and have some doubt. I would be glad if someone could clarify this for me;
1) how do i find the maximum bending moment and shear forces in the plate for my rebar design?
4) I did considered the active case in my design using surcharge load and a backfilling load both applied separately to walls. Is am i doing the right thing?
3)my base pressure is more than my bearing capacity of the soil and i don't want to increase the base nor introduce piles. What will be the appropriate solution to this?
