Concrete pedestal design
Concrete pedestal design
(OP)
I am designing a number of concrete plinths/pedestals (2m long X 0.3 X 1.3 h ) to support water tank (20000KG) mounted on top of existing slab.
Any guidance in terms of design considerations, minimum reinforcement and code detailing/embedment requirements?
It's not a wall neither can be considered as a column!
Many thanks

Minimum reinforcement will be as for other structural elements. Dowels from the slab will need to be designed similarly to ACI 318 Appendix D, however existing slab thickness and reinforcing could be an issue. I would consider either new foundations or making the new elements wider in the 0.3 m dimension, so that the overturning is resisted better by gravity loads, imposing less stress on the dowels into existing.

Designing it as a beam makes all the calculations a bit easier. So, when I've got a pedestal with low axial load that is exactly what I do.
