I am trying to validate a shaking table test of 2 story RC building in 3D, So I am imposing several displacement records with various magnitudes to my building.
After each analysis I am setting the time to zero and run it again for the next record however, I am not quiet sure that I am accumulating the damage from the previous ones or not ( because my period is changing very little in comparison with the experimental data).
I wonder if I am missing a command to rest the building before imposing the second record or there is any other way to do that.
I tried to add 2 mins of zero to the end of each record and put it back to back in one file it worked but in that way I can not take the periods after every analysis.
