1. please make sure you are using the current ATENA version (5.1.2d - there were some problems with the material model, especially under cyclic loading, in the earlier 5.0.x and 5.1.x versions).

2. Please send us your model (Troubleshooting, 2.1.1).

Best regards,
Dobromil

I am Patrick Alrassy a Graduate student at the university of Texas at Austin.
I am modeling a Reinforced concrete Column on Atena 3D sitting on a footing. And I applied cyclic loading to it (Displacement reversals). I did everything to improve the convergence: Mesh sensitivity analysis, Displacement convergence error , Break Criteria, Increase the number of load steps. But my column is failing at a very very low cycle(0.2% Drift ratio) compared to the actual experiment (4.5 %) . Can Anyone help me find the reason of the early failure?
your help is so much appreciated.
Thank you
Patrick
