Buttress design help
(OP)
Hey,
I am at present designing an underground water storage tank, howeer due to the tanks size i have had to include buttress's at 12ft intervals (5m), i have a moment coming from the surcharge and the soil to the buttress. to check for punching etc i need to calculate the force acting through the buttress to the tank's base from this moment. How is that done? thanks

Use fixed,fixed, fixed base, free top design chart and find the average moment at the base and multiply by the lenght of span from butress to butress. This will give you a good number for the moment at the counterfort.
If you do 50 x L/3, you are not assuming you have geometry of the tank helping you with the overturning but it is conservative. I hope I am making any sense. I hope the MVPs can help you soon.
