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.

Increases in computer power have now enabled engineers to combine materials science with structural mechanics in the design and the assessment of concrete structures. The techniques developed have become especially useful for the performance assessment of such structures under coupled mechanistic and environmental actions. This allows effective management of infrastructure over a much longer life cycle, thus satisfying the requirements for durability and sustainability. This ground-breaking new book draws on the fields of materials and structural mechanics in an integrated way to address the questions of management and maintenance. It proposes a realistic way of simulating both constituent materials and structural responses under external loading and under ambient conditions. Where the research literature discusses component or element technology related to performance assessment, this book uniquely covers the subject at the level of the whole system including soil foundation, showing engineers how to model changes in concrete structures over time and how to use this for decision making in infrastructure maintenance and asset management.

The report develops a computer model to predict the performance of concrete walls exposed to fire. The effects of high temperatures on the thermal properties of concrete are studied, and mathematical models representing these properties are made. A finite difference solution to the transient heat flow equation HEAT is developed to predict the temperature distribution in a wall at different time intervals throughout the ISO-834 fire test. An experimental study to measure the temperature history of reinforced concrete walls exposed to the ISO-834 fire test is described, and used to calibrate the heat transfer model.

A comprehensive review of the material behavior of concrete under dynamic loads, especially impact and impuls, opens the volume. It is followed by a summary of the various analytical tools available to engineers interested in analyzing the nonlinear behavior of reinforced concrete members for dynamic load. These range from relatively simple and practice-oriented push-over analysis to sophisticated layered finite element models. Important design-related topics are discussed, with special emphasis on performance of concrete frames subjected to seismic loads. The significance of modern software systems is recognized by including extensive examples. For readers not current in dynamic analysis methods, an appendix contains a review of the mathematical methods most commonly used for such analysis.
