Motivation

A central aspect within the mission of the fib is the release of model codes on concrete structures and related subjects. These codes should serve worldwide as the guiding science-based documents offering in a code-type version the state of the art knowledge on the planning, design, construction, execution, operation or in service performance, maintenance, rehabilitation and dismantlement or reuse of new and existing concrete structures, respectively. The model codes should meet the latest requirements and technologies in view of aspects related to safety, serviceability, durability, sustainability of structures, recognizing economic, aesthetic and other needs of different societies.

Scope and objective of technical work

The work on the Model Code (2020) was then completed in 2023. However, in 2020, during the revision of the Model Code, the world took a major turn toward carbon neutrality. And this had a major impact on our Model Code. Basically, the three main pillars of the Model Code (2020) are sustainability, a performance-based approach, and addressing new and existing structures. In the Model Code, consideration is given to low-carbon and decarbonization of concrete structures, but carbon neutrality has many uncertainties. Therefore, the Model Code (2020) needs to be maintained to update and respond to the changing situation regarding structural concrete in the future.

The mission of the second phase of COM10 is, first, to capture new knowledge on structural concrete, trends toward low-carbon and decarbonization, etc. in each of the fib committees and consolidate them in COM10 for the future edition of the Model Code. Then, improvements and supplementary rules for the Model Code will be considered by COM10 and fed back from the Task Groups and Commissions to the members. The second is to use the Model Code (2020) for actual structures and to discuss in COM10 any modifications or design or construction that may be necessary. Therefore, TG10.1, which has completed its role, has been be disbanded and two new task groups, TG10.2 and TG10.3, are formed. TG10.2 will update MC(2020) together with the respective commissions and task groups. TG10.3 will also attempt to put MC(2020) into practice by creating examples of application of the MC(2020), prepared by the YMG in collaboration with several senior engineers.
