DESCRIPTION:Modelling the ductile response of structures to earthquake loa
 ding is far from satisfactory.  Even under monotonic compression tests the
  unloading at advanced strains of simple specimens is not predicted reliab
 ly using numerical tools.  In this seminar the work at UCL\, which address
 es this problem through a reconsideration of the failure of concrete\, is 
 described.  This leads to the suggested replacement of the cumbersome set 
 of different criteria for the various stress states and their possible com
 binations with a singular\, previously proposed\, criterion of limiting te
 nsion strain.\n\nHussam Nasreddin is managing the programme for his PhD re
 search studies and John Eyre is his supervisor.\n
