NA to SS EN 1997-1 :2010(2018)-Amd 2:2024
Singapore National Annex to Eurocode 7: Geotechnical design – Part 1 : General rules
OVERVIEW
This amendment includes:
1. Modification throughout the whole standard
Replace “EN 22477-5” with “EN ISO 22477-5”.
2. Page 2, Contents
Delete “Table A.NA.12 Partial resistance factors for pre-stressed anchorages at the STR and GEO limit states”
3. Page 12, NA.4 References to non-contradictory complementary information
i) In the 1st paragraph:
a) delete [2] in “UK Design Manual for Roads and Bridges [2]”;
b) delete “CP 18”.
ii) After the 2nd paragraph, add the following new paragraph:
For grouted anchors, the design and construction are covered by SS EN 1997-1, Section 8 and BS EN 1537, respectively. However, as alluded to above, BS 8081:2015+A2:2018 provides non-contradictory complementary information on these aspects. The testing of grouted anchors is covered by EN ISO 22477-5:2018.
4. Page 13, Bibliography
i) Replace BS 1377(all parts) with the following:
BS 1377-1:2016 Methods of test for soils for civil engineering purposes ? General requirements and sample preparation
BS 1377-2:2022 Methods of test for soils for civil engineering purposes ? Classification tests and determination of geotechnical properties
BS 1377-3:2018 Methods of test for soils for civil engineering purposes ?
+A1:2021 Chemical and electro-chemical testing
BS 1377-9:1990 Methods for test for soils for civil engineering purposes –
In-situ tests
ii) Replace “BS EN 4490:2010” with “BS EN 14490:2010”;
iii) Replace “EN ISO 22477-5 Geotechnical investigation and testing – Testing of geotechnical structures. Testing of ground anchor” with “EN ISO 22477-5, Geotechnical investigation and testing — Testing of geotechnical structures — Part 5: Testing of grouted anchors”.
5. Page 21, A.3.3.4 Partial resistance factors (?R) for pre-stressed anchorages
Delete Table A.NA.12.
6. Page 25, Table A.NA.20 Values depending on anchor test method for persistent and transient design situations at the ultimate limit state and for serviceability limit states
In “Note a” replace the 2nd sentence with the following:
In Singapore, Test Method 2 is recommended.
7. Page 26, A.7 Model Factors
Delete subclause A.7.6.
