DESCRIPTION:Improving the design of reinforced concrete requir
 es a good understanding of its failure process\, w
 hich is complex because of the interplay of cracki
 ng and crushing of concrete\, yielding and rupture
  of steel\, and time dependent deterioration proce
 sses such as corrosion induced cracking. A virtual
  laboratory\, in which computer models are used to
  simulate the failure process\, plays an important
  role in elucidating the effects of material compo
 sition on structural response. This presentation d
 iscusses recent progress in developing lattice mod
 els for analysing detailed fracture and mass trans
 port processes. The application of lattice models 
 to the analysis of fracture process zones\, corros
 ion induced cracking and microcracking induced inc
 rease of permeability in concrete are discussed.\n
