DESCRIPTION:Prof. Victor Saouma\nWhen major concrete structures such as da
 ms or nuclear reactors are aging (usually due to chemically induced volume
 tric expansion such as AAR) or are rattled by earthquakes most often major
  cracks occur and jeopardize their structural integrity. Structural assess
 ment of critical and complex infrastructures is far more complex than the 
 linear elastic analysis associated with their design. Full static or trans
 ient nonlinear analyses must be undertaken. Such an analysis must be roote
 d in solid theoretical models. This talk will draw exclusively from the sp
 eaker’s personal experiences and will address the finite element modelin
 g of concrete dams and nuclear reactor containment vessels. The path from 
 testing to model to implementation to assessment and finally to applicatio
 n will be highlighted. It will be shown that nonlinear analysis can be use
 d to perform a structural safety assessment of critical infrastructures in
  lieu of simplistic (and possibly riskier or more expensive) alternate sol
 utions. Short Bio: Victor Saouma is a Professor of Civil Engineering at th
 e University of Colorado in Boulder. His research activity on dynamic anal
 ysis of dams has been funded for nine years by the Tokyo Electric Power Co
 mpany (TEPCO) on AAR by the Swiss Federal Office of Geology and Water. Mos
 t recently he was a consultant to explain the root cause for the delaminat
 ion of a nuclear containment vessel. Prof. Saouma is President elect of IF
 raMCoS and a member of the Nuclear Regulatory Commission panel on concrete
  structure deterioration.
