Story of innovation

The first release of IDEA StatiCa Connection in 2014 was a culmination of years of R&D in the field of structural engineering and specifically in the design of steel connections. IDEA StatiCa is leading a network of universities and experts that was able to solve one of the trickiest parts of structural design today. As our customer base grew to 6000 customers worldwide, it is no surprise that some companies are trying to develop a similar solution for the structural design of all steel connections.

Malpractice warning

While we cannot stop these companies from presenting pictures resembling IDEA StatiCa, we encourage all engineers to check the technology and science behind these solutions thoroughly. To our best knowledge, these programs are based on prototypes of calculation models with very few verification examples and no scrutiny from external experts. They might calculate some connections right, especially with a low loading level, but they have nothing in common with rigorous connection design of IDEA StatiCa.

Source of this comparison

This is the comparison of three software with respective versions:

  • IDEA StatiCa Steel, application Connection, version 21.0 
  • CYPE Connect Steel, version 2022.g 
  • RFEM 6 Steel joints add-on 

We listed key IDEA StatiCa features on the left and identified their status of implementation in the other two. If something is missing in IDEA StatiCa and is implemented in the other software, it is also listed.
