Abstract: The provisions to ensure a specified service life of concrete structures given in most operational standards are prescriptive in nature. Normally, the justifications of the requirements are not transparent to the reader. This paper describes an initiative to establish a methodology for handling these matters in a more analytical and transparent way when designing new structures or when assessing an existing structure's remaining service life. The methodology is based on a probability-based limit state approach in the same manner as normally applied in structural design. It is supposed that the new ISO 16204 will be published in 2012.

Keywords: service life design; limit state; probabilistic method; concrete durability; ISO 16204; concrete structures; reliability; structural design.
