ATENA Simulates Concrete Under Fire

New material models implemented in ATENA version 3.2.4 includes support for modelling material degradation due to high temperature. Check-out this new information paper about these new exciting features.

ATENA models the material degradation due to high temperature. The figure to the left shows the uniaxial compression test at various temperatures.

The thermal field calculated by ATENA is used to determine the deflection and cracking in this example of a 3D reinforced concrete beam.


Unique ATENA post-processing features allow for the graphical representation of cracking on the surface as well as in the interior of the analyzes structure.


Three figures below demonstrate ATENA capabilities for fire analysis of complex structures such as tunnels.
