DESCRIPTION:In order to meet future national CO2 emission requirements\, n
 ew challenges must be confronted with respect to concrete infrastructure. 
 One avenue towards this will be through optimized structural design accoun
 ting for hidden factors of safety already present in our structures. The p
 otential for reducing cement usage from current practice is vast\, but onl
 y if realistic and yet simple models of behaviour are used.\n\nTraditional
  nonlinear analyses of structures involves the application of complex mode
 ls with thousands of\nelements and many adjustable parameters that can be 
 difficult to assign accurately. Applying these models to large structures 
 such as tall buildings is often impossible if system-level design optimiza
 tion is also desired.\n\nThe presentation will provide such a method. Whil
 e using only\, say\, 16 elements for a simply supported beam\, it will nev
 ertheless account for shrinkage\, cracking\, creep\, yield\, shear deforma
 tions and failure\, member elongation\, and other fundamental aspects of b
 ehaviour. It has been defined to only depend on geometry and material prop
 erties and has low mesh- sensitivity.\n\nSuch novel methods will facilitat
 e nonlinear optimization and allow system reliability to be used practical
 ly by designers.
