Bridge with three or more tracks

Values in bold are different to "boxed" values in ENV 1991:1995, Table 6.6.

Dominant component action

(1) These non-dominant values may be zero where the effect is favourable.

(2) For a favourable effect this non-dominant value cannot be zero. A minimum value of 0.7 is proposed in combination with dominant traction and braking action.

(4) The simultaneity of two or three characteristic values, although unlikely, has been proposed as a simplification for groups 11, 12, 13 and 14, since no significant consequences in the design arise

(5) Based on unloaded train.

(6) The static effects from the "Unloaded Train" shall not be enhanced by the dynamic factor F but shall take into account the factor f (ENV 1991-3:1995, equation 6.6).

Annex A

Annex A of ENV 1991-3:1995 (applicable to highway bridges) is generally applicable but shall be used as indicated in clauses 4 and 5, as appropriate to highway bridges.

Annex B

Annex B of ENV 1991-3:1995 (applicable to highway bridges) is generally applicable but shall be used as indicated in clauses 4 and 5, as appropriate to highway bridges.

Annex C

Annex C of ENV 1991-3:1995 (applicable to highway bridges) is generally applicable but shall be used as indicated in clauses 4 and 5, as appropriate to highway bridges.

Annex D

Annex D of ENV 1991-3:1995 (applicable to highway bridges) is generally applicable but shall be used as indicated in clauses 4 and 5, as appropriate to highway bridges.

Annex E

Annex E of ENV 1991-3:1995 (applicable to railway bridges) is generally applicable but shall be used as indicated in clause 6, as appropriate to railway bridges.

The method for calculating dynamic factors (1 + f) for actual trains may be used, unless otherwise specified by the relevant authority.

Annex F (normative)

Basis for the fatigue assessment of railway structures

Annex F of ENV 1991-3:1995 (applicable to railway bridges) is generally applicable, unless specified by the relevant authority, but shall be used as specified in clause 6 as appropriate to railway bridges. Table F.3 gives a light traffic mix that may be used, subject to agreement with the relevant authority.
