Hi,

I am using Atena 3d to analyze Beam-column Joint under cyclic loading. My model runs well for monotonic loading. However, the same model does not run well for cyclic loading. In the fourth cycle of loading, some un-realistic deformation occurs near the joint. The screenshots of the deformed shape are attached. I tried many with different parameters but my model fails to converge at higher lateral loading.

Plz, help to resolve this issue in my model.

Thanks

Kind regards
