ATENA stands for Advanced Tool for Engineering Nonlinear Analysis, is a user friendly software for nonlinear analysis of reinforced concrete structures.

Simulates real behavior of concrete and reinforced concrete structures including concrete cracking, crushing and reinforcement yielding. Gives engineers the power to check and verify their concrete structure design in a user friendly and unique graphical environment. ATENA has over 1000 installations worldwide from Germany, Japan, India, China, USA, Finland, UK, Italy, South Korea, Australia, Thailand…etc.


Tunnel Segment

  • 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.
