DESCRIPTION:Prof. Philippe Bisch\, Ecole des Ponts ParisTech (ENCP)\, Fran
 ce\nThe majority of concrete structures have to fulfil a number of structu
 ral functions beyond that of simple resistance. These include behavioural 
 requirements for: reinforced concrete cracking\, deformability\, water and
  air leak-tightness\, sustainability.\nMost European concrete structures t
 oday are designed in accordance with Eurocode 2\, which uses a performance
 -based approach related to durability and functionality at Serviceability 
 Limit State.\nFor massive structures\, the standard rules do not fully ref
 lect the complete behaviour of massive elements\, for which thermo-hydro-m
 echanical effects\, scale effects and structural effects influence cracks 
 spacing and width. This may lead to structures which are not optimised\, e
 specially for reinforcement.\nTo 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.\nTh
 e aims of the CEOS.fr project are to:\n• develop numerical nonlinear and
  damage models\, to simulate concrete behaviour under load and deformation
 \;\n• provide engineering guidelines to optimise the design of massive c
 oncrete structures\;\n• propose further rules for crack width and crack 
 spacing assessment in massive concrete structures\, in addition to EC2 or 
 fib Model Code 2010.\nThe lecture will give general information regarding 
 the experimental and numerical aspects of the research project\, but a par
 ticular emphasis will be given to shear walls and of the conclusions which
  have been drawn for the assessment of skew cracking.\nBio : PHILIPPE BISC
 H is professor at the Ecole des Ponts ParisTech (ENPC) and has been in cha
 rge of several courses in the field of Mechanics of Structures. In paralle
 l\, he is also director at EGIS Industries\, a major engineering firm.\nHe
  has been President of the French Association of Earthquake Engineering (A
 FPS) 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.\nHe is presently the technical
  director of the research project CEOS.fr which will be presented during t
 he seminar.
