product storage retaining wall

[Tdog67]

Fellers,

I'm a structural engineer and design simple retaining walls for soil. I need to design a 10' retaining wall for the storage of granular tri-aluminum hydrate. The density is 63 pcf, what equivalent fluid pressure should i design the wall for. This is similiar to storing salt for use on highways for snow.

thanks!

It would be best to use Coulomb method for this. Let us say wall friction to be half of phi and phi to be 36 Deg and material slope to be also 36 Deg(beta), then Ka = 0.7 approx.

Equivalent fluid weight is KaY = 0.7x63= 44 pcf. If you wish you can round it to 48 pcf.
