When the classified ranges of parameters are used, the design shall be based on the maximum values of the parameters within the specified classes.

Marking 26 Licensed Copy: For the proof of fatigue strength, loads are multiplied by the dynamic factor in accordance with EN 1 -2, whilst all partial safety factors y P fn set to 1.

Consequently, in order to establish the extreme stresses in all the design critical points, several loading events or crane configurations bd be studied within the same load combination, e.

The relationship between stress amplitudes to failure 13001- fatigue and mean stress or stress ratio for the component under consideration for fatigue assessment is shown in Figure 7. A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official versions.

Static equivalent loads are given in EN 13010-1 Alternatively, advanced and recognised theoretical or experimental methods may be used in general, provided that they conform to the principles of this standard.

This is because for the same load spectrum factor, different frequencies of the net loads can produce different fatigue effects at a particular location. Using the established rules of metal fatigue the large number of variable magnitude stress cycles are condensed to one or two parameters. Figure 6 — Two-parameter representation of stress cycles 20 Licensed Copy: The total number of such operations during the useful life shall be specified. Floating cranes prEN The Red document status indicator indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS.

The BSI copyright notice displayed in this document indicates when the document was last issued. General purpose offshore cranes EN In the following clauses only a is dealt with. The above given two-parameter presentation of stress histories is shown in Figure 6. Stress histories characterised by the same value of s may be assumed to be equivalent in respect to the damage in similar materials, details or components.

The above given parameters are illustrated in Figure 4. For proof that yielding and elastic instability do not occur, the nominal stress J u due to the action of the load effects on a particular element or component shall be calculated and combined with any stresses Y u resulting from local effects. Such superimpositions een called load combinations.

The analysis of load actions from individual events or representative use of a crane representative load histories is required to reflect realistic unfavourable operational conditions and sequences of actions of the crane. Figure 1 illustrates the general layout of a proof calculation for cranes. Users of British Standards should make sure that they possess the latest amendments or editions. For the proof of fatigue strength of components the stress histories acting on them may also be directly specified, considering the service conditions, by selecting a class S according to Table 6.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Baand conflicting national standards shall be withdrawn at the latest by June For the proof of fatigue strength, the number and magnitude of significant stress cycles shall be specified. Basic load combinations are given in EN The resulting stress J, shall be compared with the allowable stress adm o.

General principles and requirements Securite des appareils de levage a charge suspendue – Krane – Konstruktion allgemein – Bz 1: The Amber document status indicator indicates that some caution is needed when using this document – it is either: A task r can be characterised by a specific combination of crane configuration and sequence of intended movements.

If there are significant differences in the displacements with different load levels, e. This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations.

Up-to-date lists and bibliographical be concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. For all crane systems, the limit state method is applicable without any restriction. Moveable cabins EN The range of total numbers of working cycles C is classified in Table 2.

Frequencies of the amplitudes of normal stresses shall be determined for positive and negative mean stresses, the frequencies of the amplitudes of shear stresses need only to be determined for positive mean stresses.
