ÖNORM EN 1993-5|Piling
This Part 5 of EN 1993 provides principles and application rules for the structural design of bearing piles and sheet piles made of steel. It also provides examples of detailing for foundation and retaining wall structures.
The field of application includes:
- steel piled foundations of civil engineering works on land and over water;
- temporary or permanent structures necessary for the execution of steel piling;
- temporary or permanent retaining structures composed of steel sheet piles, including all kinds of combined walls.
The field of application excludes offshore platforms and dolphins.
This Part 5 of EN 1993 also includes application rules for steel piles filled with concrete. These provisions might be transferred to EN 1994 in a later stage.
Special requirements for seismic design are not covered. Where relevant, the effects of ground movements caused by earthquakes should be taken into account according to EN 1998.
Design provisions are also given for waling, bracing and anchoring, see section 6.
The design of steel sheet piling using class 1, 2 and 3 cross-sections is covered in sections 4 and 5, whereas the design of class 4 cross-sections is covered in annex A.
The design procedure for crimped U-piles and straight web steel sheet piles utilises design resistances obtained by testing. It is expected that in future a separate European Standard will contain appropriate provisions for the testing of crimped points for U-piles and the testing of straight web steel sheet piles. A preliminary approach for harmonized testing procedures is given in annex B.
Geotechnical aspects are not covered in this document. Reference is made to EN 1997. Annexes C, D and E are provided only to allow a complete design of steel piling including some geotechnical aspects in accordance with EN 1997.
This allows the document to be used in the EN-stage for trial application. It is expected that after the EN-stage the location of the content these annexes will be reconsidered and the annexes will be dropped.
Provisions for taking into account the effect of corrosion in the design of piling are given in section 2 without specifying numerical values for corrosion rates due to their dependency on local conditions. Guidance on corrosion rates is given in annex F.
The design of combined walls at ultimate limit states is covered in section 5 including general provisions for the verification of primary elements. Guidance for the verification of both tubular piles and I-sections used as primary elements is given in annex G. It is expected that after the EN-stage some of the provisions for tubular piles will be harmonized with the comparable provisions in EN 1993-4.
