'''EN 1991 - Eurocode 1: Actions on structures''', is the [[European Standard]] for designing load-bearing structures. It includes characteristic values for various types of loads and densities for all materials which are likely to be used in construction.

'''In the [[Eurocode]] series of [[European Committee for Standardization|European standards]] (EN) 1991related -to [[construction]], '''''Eurocode 1: Actions on structures''''' (abbreviated '''EN 1991''' or, isinformally, the'''EC [[European1''') Standard]]describes forhow to designingdesign load-bearing structures. It includes characteristic values for various types of loads and densities for all materials which are likely to be used in construction.

'''ENEurocode 1991'''1 is subdivideddivided into thea followingnumber of parts:.

==Part 1-1: Densities, self-weight, imposed loads for buildings==

Line 19 ⟶ 21:

==Part 1-3: General actions - Snow loads==

EN 1991-1-3 gives guidance to determine the values of loads due to snow to be used for the structural design of buildings and civil engineering works. It applies for sites at altitudes below 1500m1500 m although treatments of snow loads for altitudes above 1500 m may be found in the National Annexes.

==Part 1-4: General actions - Wind actions==

Line 49 ⟶ 50:

This Part does not specifically deal with accidental actions caused by external explosions, warfare and terrorist activities, or the residual stability of buildings or other civil engineering works damaged by seismic action or fire etc. However, for buildings, adoption of the robustness strategies given in Annex A for safeguarding against the consequences of localised failure should ensure that the extent of the collapse of a building, if any, will not be disproportionate to the cause of the localised failure.

This Part does not apply to dust explosions in silos (see EN1991-1-4), nor to impact from traffic travelling on the bridge deck or to structures designed to accept ship impact in normal operating conditions ege.g. quay walls and breasting dolphins.

See also [[Structural robustness]].

==Part 2: Traffic loads on bridges==

Line 60 ⟶ 63:

* Loading principles.

* Design situations.

* Loads (road bridges),

** imposed loads due to traffic actions, their conditions of mutual combination and of combination with pedestrian and cycle traffic,

** other actions.

* Loads (footways, cycle tracks and footbridges)

** imposed loads,

** other actions.

* Loads (Railway Bridges)

** imposed loads due to rail traffic,

Line 85:

==Part 4 : Silos and tanks==

EN 1991-4 provides general principles and actions for the structural design of silos for the storage of particulate solids and tanks for the storage of fluids and shall be used in conjunction with [[EN 1990]]: Basis of Design, other parts of [[EN 1991]] and [[EN 1992]] to [[EN 1999]].
