Shear key design for base slab to resist uplift in caisson
Shear key design for base slab to resist uplift in caisson
(OP)
To resist the hydraulic uplift for a caisson, I thought of providing shear pockets (say 400x400x75mm) on the caisson walls at 1m centres horizontally so that the base wall can be cast into the shear pockets which would give good shear capacity against the uplift. Also, I was thinking to provide some dowel bars within the shear pockets.What will be the design for this dowels? Can anyone help on this?

Once the shear in the concrete is approaching its ultimate value, the strut and tie scheme will be representing the situation, in spite of the fact that at lower solicitations and on the key action the steel may not be much stressed.
