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 hs. For the verification that the serviceability limit states are not exceeded, the following aspects shall be ej, and a proof be established where appropriate: These variations, if calculated in conformity with the agreed service conditions, are the base for estimating the histories of load effects e.

The service conditions are determined by the following parameters: Limit states bbs proof of competence of machinery 3 Licensed Copy: The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and foreseeable misuse.

The total number of working cycles of a crane during its useful life can be separated into the numbers ba working cycles corresponding to several typical tasks. Non-electrotechnical equipment EN Limit states and proof of competence of machinery. Stress histories may be determined by tests or estimated from elasto-kinetic or rigid body-kinetic simulations. Figure 9 — One parameter een of stress histories frequencies of stress amplitudes referred to constant stress ratio or constant mean stress 4.

Using the established rules of metal fatigue the large number of variable magnitude stress cycles are condensed to one or two parameters.

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. Annex A is informative. Figure 2 — Typical hs chart of the limit state method 4. If there are significant differences in the displacements with different load levels, e.

In the following clauses only a is dealt with.

The Amber document status indicator indicates that some caution is needed when using this document – it is either: Limit states and proof of competence of steel structures Part 3. The allowable stress method is a special case of the limit state method, where the partial safety factors are given the same value, which combined with the resistance coefficient, forms an overall safety factor y f.

Frequencies of the amplitudes of normal stresses shall be determined for positive een negative mean stresses, the frequencies of the amplitudes of shear stresses need only to be determined for positive mean stresses. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member.

Specification for classification, stress calculations and design criteria for structures Superseded but remains current.

Basic load combinations are given in EN The analysis of load actions from individual events or representative use of rn crane representative load histories is required to reflect realistic unfavourable operational conditions 1301-1 sequences of actions of the crane.

Information regarding online access to British Standards via British Standards Online can be found at http: The transformed stress amplitudes are calculated as follows see Figure 8: Therefore it is necessary to transform the two-parameter frequencies of stress cycles into one- parameter frequencies for constant mean stress or hs stress ratio.

Figure 6 — Two-parameter representation of stress cycles 20 Licensed Copy: Magnitude, position and direction of all loads which act simultaneously in the 130011-1 of a load combination, shall be chosen in such a way that extreme load effects occur in the component or design detail under consideration.

To prevent these hazards with a margin of safety, it shall be shown that the calculated extreme values of load effects from all loads acting simultaneously on a crane and multiplied with an adequate partial safety coefficient, as well as the estimated histories of load effects, do not exceed their corresponding limit states at any critical point of the crane.

Limit states and proof of competence of rope reeving components Part 3. Consequently, in order to establish the extreme stresses in all the design critical points, several loading events or crane configurations shall be studied within the same load combination, e.

Technical principles and specifications ISO Use of an intermediate value for a parameter is permissible, but in bss case this design value shall be determined and marked instead of the class. The relative number of working cycles a r for each task r is given by the expression a. For the proof of rigid body stability it shall be shown that under the combined action of the loads multiplied by their partial safety factors no rigid body movement occurs.
