Vertical walled section

1)P The discharge loads are composed of a fixed load and a free load, called a patch load.

2) The fixed loads pwe, Phe are obtained as follows


Cw and Ch are load magnifiers according to expressions (5.22) and (5.23). For silos unloaded from the top (no flow):

In other slender silos the wall pressure magnifier and the horizontal load magnifier are:

3) The magnitude of the discharge patch pressure Pp is:


Phe is calculated from expression (5.21).

b depends on the greater of the filling and discharge eccentricities and is:

4) The calculation of patch loads for discharge may be carried out using the guidance given for patch loads for filling [ 4) to 8)]
