High Strength/High Performance Concrete (HSC/HPC) continues to be
the object of particular interest and extensive research, and its use in
construction is increasing continuously. fib Bulletin 42
summarises the available information on the material behaviour of
HSC/HPC, and develops a set of code-type constitutive relations as an
extension of CEB-FIP Model Code 1990.
Literature on
experimental data and international guidelines, standards and
recommendations were reviewed, and already-existing constitutive
relations and models were evaluated. In addition to a number of material
laws chosen and adjusted for this report, some new constitutive
relations were developed based on the collected data. The criteria for
the choice of the existing relations as well as the development of the
new constitutive relations involved their simplicity and operationality
(code-type mathematical formulations). Furthermore, they had to be
physically sound and if possible describe the behaviour of both
high-performance and normal strength concretes by a unique relation.
Finally, compliance with the specifications given in the CEB-FIP Model
Code 1990 was examined.
This State-of-art report is intended
for engineers and represents a summary of the relevant knowledge
available to and possessed by the members of the Task Group at the time
of its drafting.
