DESCRIPTION

ČSN EN 1991-1-9

1) EN 1991-1-9 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.
