Input data
The diameter of the column (b) = 16 m;
Ice thickness

(h) = 1 m;
The area of the ice field (A) = 3x3 km;
Column - vertical, conical, 1 piece;
Wind speed of 1% probability during the period of freezing (W) = 20 m / s.

Why?
The first reason for the discrepancy in the results in a

variety of methodologies is a different approach to assessing the main factors affecting the ice load.
Another reason explaining the spread is the adopted mathematical model, or the method of estimating the load, which depends mainly on the type of ice formation and the scenario of interaction.

Conclusion

Слайд 12

In conclusion, calculation result analysis of ice loads on a conical

column show that further comprehensive study of the characteristics of ice formations, strength properties and the mechanism of influence on structures in real conditions of water areas is necessary.
