The majority of concrete structures have to fulfil a number of structural functions beyond that of simple resistance. These include behavioural requirements for: reinforced concrete cracking, deformability, water and air leak-tightness, sustainability.
Most European concrete structures today are designed in accordance with Eurocode 2, which uses a performance-based approach related to durability and functionality at Serviceability Limit State.
For massive structures, the standard rules do not fully reflect the complete behaviour of massive elements, for which thermo-hydro-mechanical effects, scale effects and structural effects influence cracks spacing and width. This may lead to structures which are not optimised, especially for reinforcement.
To address these concerns, the French civil engineering community decided in 2008 to launch a joint national research project, CEOS.fr, with the aim of making a significant step forward in the engineering capabilities for predicting the expected crack pattern of massive structures under anticipated in-service or extreme conditions.
The aims of the CEOS.fr project are to:
• develop numerical nonlinear and damage models, to simulate concrete behaviour under load and deformation;
• provide engineering guidelines to optimise the design of massive concrete structures;
• propose further rules for crack width and crack spacing assessment in massive concrete structures, in addition to EC2 or fib Model Code 2010.
The lecture will give general information regarding the experimental and numerical aspects of the research project, but a particular emphasis will be given to shear walls and of the conclusions which have been drawn for the assessment of skew cracking.
Bio : PHILIPPE BISCH is professor at the Ecole des Ponts ParisTech (ENPC) and has been in charge of several courses in the field of Mechanics of Structures. In parallel, he is also director at EGIS Industries, a major engineering firm.
He has been President of the French Association of Earthquake Engineering (AFPS) and of the European Association (EAEE). He has been participating for a long time in French and European standards, mainly for aseismic design, and is one of the authors of Eurocode 8.
He is presently the technical director of the research project CEOS.fr which will be presented during the seminar.
