Abstract
The fib Model Code on 'Service Life Design' published in February 2006 in fib Bulletin, summarizes some specific methods that can be applied to design durable structures. The document contains preliminary information with a view to the available verification principles, models, and data sources. It contains the concept of carbonation and chloride-induced depassivation of the reinforcement designates serviceability limit states (SLS), in which the carbonation front has reached the surface of the reinforcing steel, or a critical, corrosion-inducing chloride content has been exceeded on the steel surface. This concept addresses exposure classes XC and XD/XS, as specified in DIN EN 206-1. A team of researchers funded by the Deutsche Forshungsgemeinschaft (DFG), are working to develop a modeling component in order to arrive at a definition of failure limit states by mid-2010. This would be applied on the basis of the hierarchically structured main and sub-models.
