Performance‐based durability design, carbonation, part 3: PSF approach and a proposal for the revision of deemed‐to‐satisfy rules

A performance based safety factor durability design format is proposed and developed with respect to carbonation of concrete. Deemed-to-satisfy rules based on a partial safety factor design approach are developed for the carbonation of concrete. This design format follows the proposed design procedure in EN 1990. For the design format the limit state equation for the carbonation is introduced in its probabilistic and safety factor format. Utilizing the PSF-approach, design charts have been derived. Values for the minimum concrete cover in dependence of material resistance and exposure class are proposed for critical environmental conditions and a design service life of 50 years.
