  2. 2. Eurocodes in Scia Engineer Scia Engineer design in any dimensionality: • from simple beam (1D), • to single plate (2D), • to whole building (3D), • to detailed analysis of distribution of internal forces over time (4D) (prestress) 1 All this in line with the Eurocodes.
  3. 3. Why use Scia Engineer for Eurocodes? • long experience with implementation of the Eurocodes • solving the complete and fully integrated Eurocode process into one software platform (e.g. 2nd order, stability, imperfections ...) • implementation of a large amount of Eurocode articles • implementation of National Annexes 2 • implementation of advanced EC checks and methods • continuous development - in line with Eurocodes progress: correction sheets, national annexes • active participation in in several EC workgroups (e.g. subcommittee EC9, fire resistance, CFS ...) • collaboration with universities, industrial partners ... • proven quality by benchmarking and 2.500 licences in use
  4. 4. Eurocode certification Certified for EC2 and EC3 CTICM (French Steel Construction Institute) - a major technical centre for steel construction in France and Europe - evaluated and certified implementation EC3 part 1-1 3 KOMO (Netherlands) evaluated and certified implementation EC2
