The 2010 fib Model Code for Concrete Structures: a new Approach to Structural Engineering Professor Joost Walraven Department of Design and Construction Structural and Building Engineering Concrete Structures Delft University of Technology
Abstract
The fib Model Code for Concrete Structures is a document which is future oriented. As such it is meant to be a guiding document for future codes. For the preparation of Eurocode 2 “Concrete Structures”, which is introduced now all over Europe, due notice was taken of the earlier Model Code work. So, the new Model Code 2010 regards actual and future developments in the field of building materials and structural design. An important new aspect in Model Code 2010 is the introduction of the aspect “time”. This means that in future structures should be designed for structural safety and serviceability for a defined number of years. This includes as well that high significance is attributed to durability, maintenance, inspection and repair, already in the state of design. This life cycle thinking is reflected by the set-up of the document. It is recognized that durability is not only a matter of durability of materials, but also of good conceptual design, in combination with good quality management in the construction stage, a good maintenance and inspection plan and the application of appropriate materials. Another important part of MC2010 is the chapter on structural materials. Extended information is given, not only on strength properties, but as well to the other most relevant behavioural aspects of concrete until a strength class C90, to open the door to defined performance design. Moreover design principles are given for fibre reinforced concrete, valid from conventional to ultra high strength fibre concrete. Furthermore, the basics for the application of non-metallic reinforcement are given. Because of the availability of powerful computers and advanced nonlinear finite element programs, rules are given on how to make optimum use of those tools, including the important aspect of reliability. Moreover a section is devoted to design by testing. MC2010 is as well written for dealing with existing structures, especially with regard to their remaining service life. In order to determine the remaining service life of a structure the reliability question is an important issue. Therefore the probabilistic safety format is introduced as an alternative for partial factor design. In the presentation an overview is given of the various aspects of the new code and background information is given.
About the Speaker
Professor Joost Walraven studied Civil Engineering at TU Delft and got his MSc in 1972. He was employed as a researcher at the Stevin Laboratory directly after his study and got his PhD degree in 1980 for the thesis: “Aggregate Interlock: an experimental and theoretical analysis”. He worked as a design engineer for Corsmit Consulting Engineers in The Hague from 1981 to 1985. He was appointed professor of Concrete Structures at the German University of Darmstadt in 1985. In 1989 he started his job as a professor of Concrete Structures at TU Delft. Professor Walraven carried out research in many areas, like shear, punching, crack width control, creep and shrinkage of concrete, rotation capacity and different types of high performance concrete. He was chairman of the Project Team for Eurocode 2 "Concrete Structures", and chairman of the committee "New Model Code for Concrete Structures".
