“ATENA is a software for analysis of concrete and reinforced concrete structures.”
ATENA user says: "One advantage using ATENA for the finite element analyses is that it calculates all material properties based on the cube strength with equations from Model Code 2010. Another great advantage with this program is that it is specially designed for concrete, which makes it easier for the user since good default values are given. The main advantage is that, even though the analyses described severe cracking, the program never had problems finding a convergent solution. A novice user can rather easy create advanced models in ATENA."

With ATENA You can simulate real behavior of concrete and reinforced concrete structures including concrete cracking, crushing and reinforcement yielding. ATENA gives you the power to check and verify their structures in a user friendly graphical environment.

Proved by over 1000 installations worldwide.

Why To Use ATENA

  • Verification of reinforcement design in critical sections.
  • Support experiments and better understand their results.
  • Design economical structures - ATENA automatically considers internal force redistribution due to cracking, which may result in reinforcement savings.
  • Assessment of existing structures.
  • Discover additional load carrying capacity.

How it works

Modeling of reinforcement

Arbitrary reinforcement arrangement can be easily included in the model either as discreete bars or as smeared reinforcement.

Bond failure can be activated just by single click. Prestressing and external cables are supported as well.


Realtime visualisation of results

Only in ATENA the engineers can observe the deformation shape and the cracking pattern even during analysis using the unique and extensive runtime visualisation capabilities.

Crack visualisation

ATENA supports realistic visualisation of cracks and cracking pattern in all stages of the nonlinear analysis a postprocessing. Cracks can be displayed not only on the surface, but also in the interior. For more realistic visualisation, only the visible cracks can be filtered.

Maintenance and support

We strongly support our users in their analytic work with ATENA. Support is mainly provided by email and phone calls. The solution to many questions can be found also in our FAQ & Online Forum. New versions of ATENA are released every year.

Maintenance is provided for free for one year after the software purchase. After that is it can be prolonged at annual rate coresponding to 15% of the program price.
