Abstract: There is a rapidly growing international demand for long-term well-performing concrete structures without premature need for maintenance and repairs. Major structures like bridges and tunnels are expected to have a long service life in the order of 100, 120 or even more years to ensure that the investment is spent in a rational way.
Past decades have shown that the classical procedures for durability of reinforced concrete structures have often failed to provide reliable long-term performance in aggressive environments. Within Europe this awareness has led to the development of new service life design approaches to provide necessary and valuable tools to satisfy present day design needs.
These new design tools allow the grossly over-simplistic deem-to-satisfy durability design methods of traditional codes and standards to be replaced with rational scientifically sound service life design methods using the same reliability based methods as used for decades for structural design. These new service life design tools have been implemented in fib bulletin No. 34 Model Code for Service Life Design and will be part of the new fib Model Code for Service Life. Furthermore, it will be transferred into an ISO standard in the near future.
COWI spearheading the international developments for such rational service life design methods during the last decades has adopted this new service life design approach for the several larger infrastructures worldwide.
The paper presents one of today´s most upfront durability design methodology exemplified by some case studies.
