(Amendment)Eurocode 1 - Actions on structures - Part 1-3: Snow loads
Eurocode 1 - Actions on structures - Part 1-3: Snow loads
1.1 Scope of EN 1991-1-3
(1) EN 1991-1-3 gives principles and rules to determine the values of loads due to snow to be used for the structural design of buildings and civil engineering works.
(2) This document does not apply to sites at altitudes above 1 500 m, unless otherwise specified.
NOTE For rules for the treatment of snow loads for altitudes above 1 500 m, see 6.1.
(3) This document does not give guidance on specialist aspects of snow loading, for example:
- impact snow loads resulting from snow sliding off or falling from a higher roof;
- changes in shape or size of the construction works due to the presence of snow or the accretion of ice which could affect the wind action;
- loads in areas where snow is present all year round;
- lateral loading due to snow creep (e.g. lateral loads exerted by drifts);
- loads due to artificial snow.
1.2 Assumptions
The assumptions given in EN 1990:2023, 1.2 apply.

1.1 Področje uporabe EN 1991-1-3
(1) EN 1991-1-3 določa načela in pravila za določanje vrednosti obremenitev zaradi snega, ki se uporabljajo pri projektiranju konstrukcij stavb in gradbenih del.
(2) Ta dokument se ne uporablja za lokacije na nadmorski višini nad 1 500 m, razen če ni drugače določeno.
OPOMBA Za pravila o obravnavi snežnih obremenitev za nadmorske višine nad 1 500 m glej 6.1.
(3) Ta dokument ne daje smernic za specializirane vidike snežnih obremenitev, na primer:
- udarne snežne obremenitve, ki izhajajo iz zdrsa snega ali padca z višje strehe;
- spremembe oblike ali velikosti gradbenih del zaradi prisotnosti snega ali nabiranja ledu, kar bi lahko vplivalo na delovanje vetra;
- obremenitve na območjih, kjer je sneg prisoten vse leto;
- bočne obremenitve zaradi plazenja snega (npr. bočne obremenitve, ki jih povzročajo zameti);
- obremenitve zaradi umetnega snega.
1.2 Predpostavke
Predpostavke, navedene v EN 1990:2023, 1.2, veljajo.
