Nonlinear analysis
of concrete structures.
Software and expert consulting to help you understand how concrete structures behave – from cracking to failure. Trusted by engineering firms, research institutions, and infrastructure operators in more than 60 countries.
What We Do
Three decades of expertise in nonlinear finite-element analysis – built into our software, applied in consulting, and shared through training.
Software
ATENA, SARA, AmQuake, and FReET – specialist tools for nonlinear structural analysis, seismic assessment, and reliability analysis.
Consulting
Expert analysis for critical infrastructure, including bridges, dams, nuclear containment, and deep foundations.
Training
Practical courses and workshops to help engineering teams apply nonlinear analysis with confidence – on-site or online.
Research
We collaborate with universities and research institutions to develop and validate new analysis methods and material models.
Our Software
Modelling tools used in design offices, research labs and infrastructure projects worldwide.

Industries We Serve
Where every detail matters.
Verification and assessment of structural details
Where design codes run out of simple rules, nonlinear analysis shows how the detail actually carries load, cracks and fails.
- Column-beam connections
- Shear strength of beams and girders with openings
- Slab shear-punching behaviour
- Shear walls with openings
- Anchorage to concrete
- Reinforcement detailing
- Precast concrete elements
