Cyclic loading

[Haitham AbdelMalek]

Hello, 

I am modelling a reinforced concrete beam under cyclic loading. I defined the displacement loading protocol as in the attached picture. I get an error of curve vertical slope. Could someone please let me know how i can correct it. 

 *** Error 20444 (STR+444)
     load curve 1 has vertical slope
     Check that this curve is correct

Thanks,

Haitham

It might help to provide a list of the X-Y points.    --len

Here is the list of displacement (mm) loading points vs time (ms).

Does your simulation end (even slightly) after T=31, i.e. so LS-DYNA needs to extend your cyclic data?                       --len

Please provide a copy the LS-DYNA input file lines as you may have a formatting error in your input.          --len
