ATENA is a user friendly software for nonlinear analysis of reinforced concrete structures.
ATENA user Richard Malm says in his Ph.D. thesis: "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 your structural design in a user friendly graphical environment.

Proved by over 1000 installations worldwide.

Why To Use ATENA

  • ATENA is for engineers that want to understand the real structural behavior.
  • It is a great addition to standard design programs that usually supports engineers to work quickly and satisfy the code requirements,
  • ATENA is excellent for verification of reinforcement design in critical sections.
  • For design of economical reinforced concrete structures - ATENA automatically considers internal force redistribution due to cracking, which may result in reinforcement savings.
  • For assessment of existing structures.
  • It helps to discover additional load carrying capacity.
  • It supports advanced research in reinforced concrete structures or modern cementitious materials.

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 post-processing. 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.
