The DuraCrete approach
conference paper
In the past years much efforts have been spent on a new design approach for the durability of existing and new concrete structures. The results of these efforts can be seen in recent work of several international scientific committees of Rilem, CEB, CIB and FIER These have finally resulted in the Brite/Euram project DuraCrete where a design manual has been developed for a service life design of concrete structures. The new design method is based on performances (both serviceability and ultimate limit states), reliability and a distinct design service life. This is in contrast with the conventional design approach, that is based on deem-to-satisfy rules, mainly to prevent degradation of the concrete. DuraCrete offers the possibility to make tailor made designs based on performance characteristics of the materials involved and focussing on the specific environment, use and maintenance strategy for the structure. The method has a high potential for use in practice as it can directly be connected to the modern structural design approach. The project DuraCrete was completed in 1999. Since then new developments have occurred, indicating the new possibilities and advantages of the new service life design method. One of the examples is the design of the Western Scheldt Tunnel, the European thematic network DuraNet and further steps in the process of the development of codes. The paper will highlight these examples and delve into the significance for the concrete industry and the society.
