What is BS EN 13001‑3‑1 - Limit States and proof competence of steel structure about?
BS EN 13001‑3‑1 is to be used together with BS EN 13001-1 and BS EN 13001-2 and as such they specify general conditions, requirements, and methods to prevent mechanical hazards of cranes by design and theoretical verification. The machinery concerned and the extent to which hazards, hazardous situations, and events are covered are indicated in the scope of BS EN 13001‑3‑1.
The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during intended use and reasonably foreseeable misuse. Clauses 4 to 8 of BS EN 13001‑3‑1are necessary to reduce or eliminate risks associated with the following hazards:
- Exceeding the limits of strength (yield, ultimate, fatigue)
- Exceeding temperature limits of material or components
- Elastic instability of the crane or its parts (buckling, bulging)
BS EN 13001‑3‑1 is not applicable to cranes that are manufactured before the date of their publication as EN and serve as a reference base for the European Standards for a particular crane type.
Note1: Specific requirements for particular types of cranes are given in the appropriate European Standard for the particular crane type.
Note2: BS EN 13001-3-1 deals only with the limit state method in accordance with BS EN 13001-1.
Who is BS EN 13001‑3‑1 - Limit States and proof competence of steel structure for?
BS EN 13001‑3‑1 on limit States and proof competence of steel structure is useful for:
- Manufacturers of cranes
- Designers of crane steels structures
- Operators of cranes
- Safety regulatory bodies
Why should you use BS EN 13001‑3‑1 - Limit States and proof competence of steel structure?
Nominal stress is a stress in the base material adjacent to a potential crack location, calculated in accordance with simple elastic strength of materials theory, excluding local stress concentration effects. The stresses are calculated in accordance with the nominal stress concept.
BS EN 13001‑3‑1 is based on nominal stresses, i.e. stresses calculated using traditional elastic strength of materials theory which in general neglect localized stress non-uniformities. When more accurate alternative methods of stress calculation are used, such as finite element analysis, using those stresses for the proof given in BS EN 13001‑3‑1 may yield inordinately conservative results.
BS EN 13001‑3‑1 has been prepared to be a harmonized standard to provide one means for the mechanical design and theoretical verification of cranes to conform to the essential health and safety requirements of the Machinery Directive, as amended. BS EN 13001‑3‑1 also establishes interfaces between the user (purchaser) and the designer, as well as between the designer and the component manufacturer, in order to form a basis for selecting cranes and components.
What’s changed since the last update?
BS EN 13001‑3‑1:2012+A2:2018 supersedes BS EN 13001‑3‑1:2012+A1:2013, which is withdrawn.
CEN/TC 147/WG 2 has made a new edition of BS EN 13001-3-1 to adapt the standard as follows:
- New steel qualities from BS EN 10149-2 and stainless steels from BS EN 10088-2 added
- Application of bolt preloading scatter was modified
- Table 8 changed to exclude matching material for ultra-high strength steel
- Fatigue strength specific resistance factors were adjusted
- Requirements for fatigue testing were modified
- Formula for assessing combined effect of normal and shear stresses was changed
- Improved for calculation of fillet welds
- Characteristic fatigue strengths modified for notch cases
