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. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. Figure 5 — Example for class P 4. The above given two-parameter presentation of stress histories is shown in Figure 6. Hs of its special character, the allowable stress method is only reliable in specific cases.

Figure 1 illustrates the general layout of a proof calculation for cranes. Limit states and proof of competence of steel structures Part 3.
When the classified ranges gs parameters are used, the design shall be based on the maximum values of the parameters within the specified classes. This European Standard shall be given the status of a national standard, either by publication of 13001-11 identical text or by endorsement, at the latest by Juneand conflicting national standards shall be withdrawn at the latest by June For the proof of fatigue strength of components the stress histories acting on them may also be directly specified, considering the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.
Alternatively, advanced and recognised theoretical or experimental methods may be used in general, provided that they conform to the principles of this standard. Click here to find out how to access this document. rn

In some applications the effect of occasional loads can occur regularly. Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service. If a different level of safety is required in some instance, a risk factor y n may be agreed upon and applied. General principles and requirements AMD The machinery concerned rn the extent to which hazards are covered are indicated in the scope of this standard.
A flow chart illustrating the allowable stress method is shown in Figure 3. The limit state method see 4. When establishing the load combinations, consideration shall be bd to the use of the crane, taking into account its control 13001- its normative instructions for use, and any other inherent conditions, where they relate to the specific aim of the proof of competence.
The transformed stress amplitudes are calculated as follows see Figure 8: Want access to British Standards?
C is the total number of working cycles during the useful life of the crane; C r is the number of working cycles of 133001-1 r.

Annex A is informative. BSI offers members an individual updating service called PLUS which ensures that subscribers automatically receive the latest editions of standards. In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested.

Specification for classification, stress calculations and design of mechanisms incorporating amendments No. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Een Secretariat or to any CEN member. Non-electrotechnical equipment EN BSI also holds the copyright, in the UK, of the publications of the international standardization bodies. The stress histories from these occasional loads may be estimated in the same way as those from the regular ones and shall be taken into account for the fatigue assessment.
Hazards can occur if extreme values of load effects or their histories exceed the corresponding limit states. Table 4 shows the classes Q of load spectrum factors kQ.
A list of organizations represented on this subcommittee can be obtained on request to its secretary.
The proof of competence according to EN shall be carried out by using the general principles and methods appropriate for this purpose and corresponding with the recognised state of the art in crane design. When Parts 1, 2, 3. Load actions Part 3. Service conditions are considered in a general way, independent of the type of crane and the way it is driven. Where details concerning 130001-1 numbers of working cycles and the masses of the particular net loads to be handled are not known, an appropriate relative frequency shall be agreed between the user, manufacturer and designer for each task r.
