'''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.▼

==
EN 1991-1-1 gives design guidance and actions for the structural design of buildings and civil engineering works including some geotechnical aspects for the following subjects:
Line 10 ⟶ 12:
# Imposed loads for buildings.
==
Part 1-2 of EN 1991 deals with thermal and mechanical actions on structures exposed to fire. It is intended to be used in conjunction with the fire design Parts of [[EN 1992]] to [[EN 1996]] and [[EN 1999]] which give rules for designing structures for fire resistance.
Line 18 ⟶ 20:
Part 1-2 of EN 1991 gives general principles and application rules in connection to thermal and mechanical actions to be used in conjunction with [[EN 1990]], EN 1991-1-1, EN 1991-1-3 and EN 1991-1-4.
==
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
▲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 1500m although treatments of snow loads for altitudes above 1500 m may be found in the National Annexes.
▲==EN 1991-1-4: Actions on structures - Part 1-4: General actions - Wind actions==
EN 1991-1-4 gives guidance on the determination of natural wind actions for the structural design of building and civil engineering works for each of the loaded areas under consideration. This includes the whole structure or parts of the structure or elements attached to the structure, e. g. components, cladding units and their fixings, safety and noise barriers.
Line 28 ⟶ 29:
EN 1991-1-4 is applicable to:
==
EN 1991-1-5 gives principles and rules for calculating thermal actions on buildings, bridges and other structures including their structural elements. Principles needed for cladding and other appendages of buildings are also provided.
Line 37 ⟶ 38:
EN 1991-1-5 describes the changes in the temperature of structural elements. Characteristic values of thermal actions are presented for use in the design of structures which are exposed to daily and seasonal climatic changes. Structures not so exposed may not need to be considered for thermal actions.
==
EN 1991-1-6 provides principles and general rules for the determination of actions which should be taken into account during the execution of buildings and civil engineering works.
==
EN 1991-1-7 provides rules for safeguarding buildings and other civil engineering works against accidental actions. For buildings, EN 1991-1-7 also provides strategies to limit the consequences of localised failure caused by an unspecified accidental event. The recommended strategies for accidental actions range from the provision of measures to prevent or reduce the accidental action to that of designing the structure to sustain the action.
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

==EN 1991-2: Actions on structures - Part 2: Traffic loads on bridges==▼
EN 1991-2 defines imposed loads (models and representative values) associated with road traffic, pedestrian actions and rail traffic which include, when relevant, dynamic effects and centrifugal, braking and acceleration actions and actions for accidental design situations.
===Contents===
==Part 3: Actions induced by cranes and machinery==
▲# Loads (road bridges),
▲## imposed loads due to traffic actions, their conditions of mutual combination and of combination with pedestrian and cycle traffic,
▲## other actions.
EN 1991-3 specifies imposed loads (models and representative values) associated with cranes on runway beams and stationary machines which include, when relevant, dynamic effects and braking, acceleration and accidental forces.
▲# Loads (footways, cycle tracks and footbridges)
▲## imposed loads,
▲## other actions.
===Contents===
▲# Loads (Railway Bridges)
▲## imposed loads due to rail traffic,
▲## other actions.
* Common definitions and notations.
* Actions induced by cranes on runways.
* Actions induced by stationary machines.
==Part 4 : Silos and tanks==
{{European Standards}}▼
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]].
