ATENA is a finite element based software designed specifically for the analysis of reinforced concrete. With ATENA users can simulate the actual behavior of concrete structures, including concrete cracking, crushing, and yielding of the reinforcement thereby producing a more accurate prediction of load carrying capacity. Additionally, ATENA provides a unique run-time environment, allowing users to see this behavior in real time, as the structure is being analyzed.
Static, Dynamic, Creep, Thermal, Moisture, Fatigue, and Seismic analyses are all supported in ATENA along with several advanced solution methods and solvers. Advanced/non-linear material models (concrete, steel, rock, soil, and masonry) are then used to accurately model the properties of the structure. Designed specifically for analysis of concrete, ATENA can automatically generate the required concrete properties based on standard material test procedures. ATENA also includes options for the analysis of modern fiber reinforced concrete materials: SHCC, ECC, HPRFC, UHPFRC, as well as fiber wrapping and lamellas.
The unique runtime environment allows visualization of results in real-time. Users can see crack developments, and contoured results as the analysis progresses. Monitoring points can be defined to produce desired output curves (ex. load vs displacement). 3D cuts can also produce internal moments, normal forces, and shear displays. Parallel processing is supported and provides a 3-4x reduction in computation times.
