Is it possible to input ASD values for Random Response Analysis? I have the input as time vs acceleration plot and the file of the type .dat.

Will it be possible to input these data for my TABRND? or is there any other way one can suggest.

 

It would be really helpful. Thanks in advance :)

    Hi Prashanth
    You need to transform your time signal, a(t) to a PSD table and use that in the TABRND1 table!
    To go from a(t) to PSD you can for example use Altair compose and pwelch function on a(t)
