DESCRIPTION:Seminar overview:\nIn the UK\, we spend nearly £300k every ye
 ar constructing piles to resist loads based on ultimate factors of safety 
 or partial resistance factors. Is this the right design approach? There ar
 e hundreds of geotechnical and structural engineers designing piles to res
 ist different Eurocode Combinations\, but what is it that we are designing
  for. What does a factor of safety mean in the context of pile design? How
  do we define pile performance and how is this captured in pile specificat
 ion criteria for pile testing? In this talk\, Dimitrios will explore what 
 really matters when we design piles. Dimitrios will refer to some of the c
 hallenges of designing piles to Eurocodes and will present an alternative 
 framework leading to a design based on performance. The presentation will 
 include results from a database of pile tests in clay supporting the notio
 n of performance driven pile design.\n\nBiography:\nDimitrios Selemetas is
  the chief geotechnical engineer of Cementation Skanska with over 15 years
  of experience on the design and construction of piled foundations and dee
 p basements. Dimitrios was awarded a PhD from Cambridge University on the 
 effects of tunnelling on full-scale piled foundations and piled structures
 . He gained consultancy experience with Mott MacDonald and field instrumen
 tation experience with CMCS at the Building Research Establishment (BRE) b
 efore joining the piling and foundations division of Skanska. At Cementati
 on he has developed specialist skills in the geotechnical and structural d
 esign of piled foundations and embedded retaining walls focusing on constr
 uctability and performance driven designs. Dimitrios has been the contract
 or design leader for some challenging basement and foundation works includ
 ing the Nova Victoria basement in London and the AstraZeneca basement in C
 ambridge. Dimitrios has been actively involved in the evolution of geotech
 nical and structural Eurocodes\, he is one of the co-authors of the new CI
 RIA 760 report on the design of embedded retaining walls and has received 
 the Cooling Prize of the British Geotechnical Association for his research
  work at Cambridge University.\n
