Technical aspects

Annotation of standard text ČSN EN 1991-1-9 (730035):

gives principles and rules to determine the values of loads due to atmospheric icing to be used for following types of structures:

• - masts;
• - towers;
• - antennas and antenna structures;
• - cables, stays, guy ropes and similar structures;
• - rope ways (cable railways);
• - structures for ski-lifts;
• - buildings or parts of them exposed to potential icing;
• - special types of structures, such as towers for transmission lines and wind turbines.

NOTE - Atmospheric icing on electrical overhead lines is covered by EN 50341-1.

2) EN 1991-1-9 specifies values for:

• - dimensions and weight of accreted ice;
• - shapes of accreted ice.
• 3) EN 1991-1-9 covers types of icing, ice loads acting on structures, and falling ice considerations.

NOTE - For wind actions on iced structures, see EN 1991-1-4.

Assumptions:

The assumptions given in EN 1990:2023, 1.2 apply.

EN 1991-1-9 is intended to be used with EN 1990 (all parts), the other parts of EN 1991 and EN 1992 (all parts) to EN 1999 (all parts) for the design of structures
