I have a problem requiring me to determine the base moment to a stockpile tower (to enable check of tower, base fixings and footing).

The steel tower (0.6 m diameter) feeds sand (angle of repose 30-35 deg) and is located 4.6 m from the centre of an 11.0 m high stockpile, boom from top of tower outstands 4.6 m. The sand is removed by Front-end Loader, and may be wet.

I therefore need to determine the active (or flow ?) pressures to the high side (8.5 m of material) and any passive resistance reducing the resulting base moment for the low side (8.25m or less ?)

I would seek a proven design approach, published references and/or research results for this problem.

Thank you and regards,
