Over recent years there has been discussion of the possibility of reducing the partial safety factor for reinforcement. This paper puts the case for a reduction from the present value of 1.15 to 1.05. The case is made on three grounds:
- 30 years experience with the current safety levels
- comparison with structural steel design where lower factors are used
- comparison of current sufety level with the recommendations of Eurocode 1.
