This document discusses the implementation of Eurocodes in the structural analysis software Scia Engineer. It summarizes that Scia Engineer allows for design in accordance with Eurocodes in 1D, 2D, 3D, and 4D. It has extensive experience implementing Eurocodes and participates in various Eurocode workgroups. Scia Engineer is certified for implementation of EC2 and EC3 and was found to be a best performer in commercial Eurocode software by the European Commission.

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)

All this in line with
the Eurocodes.

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
