Omfang

(1) 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. (2) Imposed loads defined in EN 1991-2 are intended to be used for the design of new bridges, including piers, abutments, upstand walls, wing walls and flank walls etc., and their foundations. (3) The load models and values given in EN 1991-2 should be used for the design of retaining walls adjacent to roads and railway lines. NOTE For some models only, applicability conditions are defined in EN 1991-2. For the design of buried structures, retaining walls and tunnels, provisions other than those in EN 1990 to EN 1999 may be necessary. Possible complementary conditions may be defined in the National Annex or for the individual project. (4) EN 1991-2 is intended to be used in conjunction with EN 1990 (especially A2) and EN 1991 to EN 1999. (5) Section 1 gives definitions and symbols. (6) Section 2 defines loading principles for road bridges, footbridges (or cycle-track bridges) and railway bridges. (7) Section 3 is concerned with design situations and gives guidance on simultaneity of traffic load models and on combinations with non-traffic actions. (8) Section 4 defines : - imposed loads (models and representative values) due to traffic actions on road bridges and their conditions of mutual combination and of combination with pedestrian and cycle traffic (see section 5) ; - other actions specifically for the design of road bridges. (9) Section 5 defines : - imposed loads (models and representative values) on footways, cycle tracks and footbridges ; - other actions specifically for the design of footbridges. (10) Sections 4 and 5 also define loads transmitted to the structure by vehicle restraint systems and/or pedestrian parapets. (11) Section 6 defines : - imposed actions due to rail traffic on bridges ; - other actions specifically for the design of railway bridges and structures adjacent to the railway.
