SCIA Engineer | Technical Specifications


General - SCIAEngineer user environment

  • Object-oriented: with a simple right-click of the mouse button you can modify, delete, copy… everything, everywhere
  • Well-structured property dialogues are used for fast viewing and editing of all object-properties
  • “Parametric Modelling”: geometry and loads
  • Templates and user defined models: individual generators
  • “Autodesign” of steel profiles and concrete reinforcement according to different codes
  • Several languages to be selected for the user interface and reporting: English, Dutch, German, French, Czech, Slovak, Spanish, Romanian and Russian

Modeller - Input of your Structure


  • Beams can be straight, curved, with haunches, with holes or completely arbitrary
  • Flat or curved surfaces of constant or variable thickness can have intersections with cut-outs, holes, sub-regions of different thickness or ribs
  • The calculation model is 2D and 3D with a perfect integration of beams and surfaces
  • A wide range of cross-sections is available in the standard profile library. It includes standard steel cross-sections (HEA, IPE, L, RHS, CHS, C, T…), concrete cross-sections, welded sections, thin-walled sections, pairs of sections, sheet welded sections, composite sections, aluminium sections, bridge sections…

  • Construction stages (linear and non-linear)concrete04-1s
  • Sequential analysis: results from one analysis are used as the initial state for a new analysis


  • A wide variety of results in beams and slabs is viewed: deformations, internal forces, supports reactions, connections forces, internal stresses, contact stresses, foundation load table…
  • Results are viewed generally for the whole structure or detailed for a selection of elements
  • The graphical representation of results is flexible and the user chooses between different possibilities


Output - The document

  • The user defines the layout of the document:
  • Tables should be printed
  • The contents and layout of each table
  • “ChapterMaker”, fast creation of pictures and tables
  • Customizable front page, headers and footers
  • The order: by load case, by element …
  • Picture gallery for graphical views
  • The document is dynamic: the tables with results are updated automatically when the input data are changed and the structure is recalculated
  • Well-structured output is obtained using the automatic paragraph numbering
  • The user-defined layouts are stored as a template so that they can be reused for other projects
  • “Active Document”: the user may change the project input data in the document.
  • The project model will be adapted automatically, the structure is recalculated and the document (results…) will be adapted accordingly
  • The document is exported to HTML, ASCII, RTF, PDF, PDF 3D
