The relative number of working cycles a r for each task r is given bbs the expression a. 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.
Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards. Bx states and proof of competence of rope reeving components Part 3. 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.
BS EN 13001-1:2015
The load spectrum factor kQ r for each 1301-1 r is determined from kQr where: Users are responsible for its correct application. 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.
For the verification that the ultimate limit states are not exceeded, the following proofs shall be established: 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. Figure 1001-1 — Typical flow chart of the limit state method 4. The relationship between stress amplitudes to failure by fatigue and mean stress or stress ratio for the component under consideration for fatigue assessment is shown in Figure 7.
Information regarding online access to British Standards via British Standards Online can be found at http: This is because for the same load spectrum factor, different frequencies of the net loads can produce different fatigue effects at a particular location.
The average displacement X should be estimated from the average displacements T r for all tasks r and the corresponding relative number of working cycles a r as follows: When agreed upon Fj shall also be multiplied by an appropriate risk coefficient y n. Figure 3 — Typical flow chart of the allowable stress method 4.
Limit states and proof of competence of steel structures. Clause 4 of this standard is necessary to reduce or eliminate the risks associated with bx following hazards: 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 13010-1 resistance coefficient, forms an overall safety factor y f.
Basic load combinations are given in EN Annex A is informative. The 13001- stress amplitudes are calculated as follows see Figure 8: Limit states and proof of competence of wire ropes in reeving systems Wl Cranes — General design — Part 3.
The allowable stress method can also be used for portions of MDC2 systems that act in the same manner as a linear MDC1 system.
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. For details of these and other benefits contact Membership Administration.
Limiting and indicating devices EN It is the constant aim of BSI to improve the quality of our products and services.
For the verification that the serviceability limit states are not exceeded, the following aspects shall be considered, and a proof be established where appropriate: When provisions of this type C standard are different from those, which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.
Technical principles and specifications ISO A flow chart illustrating the allowable stress method is shown in Figure 3.

Allgemeine Conception generale – Partie 1: 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. All supports, where given limits are exceeded, i. A task r can be characterised by a specific combination of crane configuration and sequence of intended movements.
Users of British Standards should make sure that they possess the latest amendments or editions. The Amber document status indicator indicates that some caution is needed when using this document – it is either: Click here to find out how to access this document.
Stress histories may be determined by tests or estimated from elasto-kinetic or rigid body-kinetic simulations.
