  ATENA Engineering 2D
Version 4.2.7g - June 2011


ATENA is a state-of-the-art software package for advanced static and dynamic analysis of concrete and reinforced concrete structures. It can simulate the real behavior of the structure, including effects such as concrete cracking, crushing and reinforcement yielding. It gives engineers the power to check and verify their structures in a user friendly and unique graphical environment. With over 400 installations worldwide, ATENA is the successful successor to the established finite element software SBETA. ATENA is developed by Červenka Consulting, Ltd. (


  • Finite Elements
    • 2D isoparametric elements, quadrilateral, triangular. Axisymmetrical elements.
    • Truss elements for reinforcement.
    • Spring supports.
    • External cable elements.
    • Interface, gap.
  • Material models
    • 2D SBETA concrete model, also for high strength and SFRC : smeared cracks, crack-band, fracture-energy-based softening, Kupfer’s compressive failure, variable shear retention, strength reduction of cracked concrete.
    • 3D fracture-plastic concrete model based on Menetrey-Willam law : smeared cracks, fracture-energy based softening, Compression Field Theory aggregate interlock in shear, non-associated plasticity, user defined functions, variable parameters.
    • Reinforcement bi-linear and multi-linear. Reinforcement with bond.
    • Von-Mises plasticity for metals.
    • Drucker-Prager plasticity with associated / non-associated flow rule for rock and soil.
    • Bazant M4 microplane concrete.
    • Reinforcement cyclic.
    • Interface with Mohr-Coulomb material law.
    • Isotropic elastic.
    • Non-linear springs.
  • Loading
    • Load cases : body forces, loading forces, supports, prescribed deformations, temperature, shrinkage, prestressing.
    • Load steps : combination of load cases, solution methods.
    • Arbitrary load history in steps, non-proportional, cyclic.
    • Construction process (indirectly - see respective manual).
  • Solution methods
    • Direct solver of equations.
    • Newton-Raphson and modified Newton-Raphson.
    • Arc-length. Line-search.
    • Tangential and elastic stiffness predictors.
  • Graphical user interface
    • 2D GUI. Graphical user interface : pre-processing (geometrical modeling, reinforcement (bars, smeared), automatic meshing, material properties, loading and supports, solution methods, monitoring), solution (non-linear FE solution, graphical monitoring, restart), post-processing (iso-lines, iso-areas, rendering, vectors, tensors, cracks, response diagrams, cuts/sections, internal forces (N,V,M), user-defined numerical output).
Minimum hardware requirements
  •  MS Windows XP SP2/W7/Vista SP1/2000 SP4 Rollup 1, 512 MB RAM memory (1GB for W7 and Vista) and 40 GB HDD, graphics resolution 1024x768.
Recommended hardware requirements
  •  MS Windows XP/Vista/7, 4GB RAM memory, 500 GB hard disk, graphics card with resolution of 1280x1024 and OpenGL 3D-acceleration, designed for CAD (e.g. nVidia Quadro, ATI FireGL/FirePro).
