1) For structures carrying more than two tracks the more unfavourable of the two cases a) and b) shall be taken.

Note: LM71"+" SW/O means Load Model 71 and if relevant SW/O for continuous bridges.

(5)P For the verification of deformations and vibrations the vertical loading to be applied shall be:

- Load Model 71 increased by the dynamic factor $ when determining deformations and

- the actual train traffic increased by the relevant dynamic factor when determining the dynamic behaviour in the case of resonance or excessive vibrations of the deck.

Note: See annex H for evaluating dynamic factor.

(6)P For bridge decks carrying double track the checks for the limits of deflection and vibration shall be made with only one track loaded.

(1) Unless otherwise specified, the simultaneity of the loading defined in 6.3 to 6.5 and 6.7 is taken into account by considering the groups of loads defined in Table 6.6. Each of these groups of loads, which are mutually exclusive, shall be considered as defining a characteristic action for combination with non-traffic loads.

Table 6.6: Assessment of groups of traffic loads (characteristic values of the multicomponent actions)

Note: The factors given in the Table are to be applied to the characteristic values of the different actions considered in each group. All the proposed values given for these factors are to be considered as boxed values.
