Traditional requirements for constituent materials, limiting w/b-ratios and cement contents are often not applicable for modern construction and modern types of concretes. With the advancement of testing methods for fresh and hardened concrete properties, a performance-based design and specification of concrete and concrete structures is approaching and already frequently applied. However, an independent overview is still missing on how a performance-based approach can be generalised – for both mechanical and durability aspects. In a first step fib Task Group 4.5 (TG4.5) intends to provide further information in addition to the new fib Model Code for Concrete Structures 2010 (MC2010) and how performance-based specifications can be adopted for the given models and design rules.
