Revision of European standards

This result covers proposed amendments to European standards when the new low-nickel stainless steel HSS3 is used as reinforcement in concrete structures instead of normal carbon steel. The current topics for possible amendments were identified, and the following topics are covered:
-Durability (EN 1992-1-1, Eurocode 2-1-1).
- Structural design of concrete structures (EN 1992-1-1, Eurocode 2-1-1).
-Design of concrete structures under seismic action (prEN 1998-Parts 1 and 2, Eurocodes 8-1 and 8-2).
-Design of concrete structures under fire action (EN 1991-1-2, EN 1992-1-2 and prEN 1993-1-2, Eurocodes 1-1-2, 2-1-2 and 3-1-2).
-Repair and strengthening of concrete structures (prEN 1504-series).

For durability, some relaxations are proposed. For the other topics it is concluded that Design rules in the European standards are applicable for the HSS3 steel. However, the properties of the steel are such that it is not beneficial to employ HSS3 steel compared to carbon steel.

The main users of the result are standard making organisations, especially CEN, consultants and other users of the new reinforcing steel.
