Abstract
Work has recently started in fib (Fédération Internationale du Béton) on the preparation of a new fib Model Code for Concrete Structures, under the working title of Model Code 2020 (MC2020). This will be a single code dealing with both new and existing concrete structures, that is both the design of new structures and all the activities associated with the assessment, interventions and the through-life management and care of existing concrete structures. Numerous goals relating to durability and service life design have been identified, including that ideally MC2020 should incorporate:
• Better models for deterioration processes addressing issues such as propagation stage deterioration, deterioration processes not currently addressed in fib MC2010, the influence of cracking and the existence of a wider range of aggressive service environments and situations than previously considered.
• Improved models for service life prediction / estimation
• Models for ‘repaired’ structures / intervention behaviour
• Reliability requirements for new and existing structures
• Consideration of the use and value of monitoring data / the level of knowledge available for decision making in the through-life management and care of concrete structures.
The paper provides background to the work being undertaken in each of these areas.
