Hi

can anyone suggest any reference book which gives solved example of structural steel hopper design based on En 1991-4-2006. I am designing a  hopper for boiler building based on the eurocode , however finding it difficult to understand certain formulas given in section-6 of the code.

for example

beta =24
s=1
Uh=0.38
b=0.2, then as per expression 6.18, the value n comes out to be 0.68

however the term in denominator for calculating Pv is n-1 and hence the pressure value becomes negative. which i think is no possible.

hope someone can throw light on it. i have attached herewith the relevant pages of the code for ready reference

Regards
