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.

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
