The input seismic wave data to LSDYNA model

[Yahia Halabi]

Hello everyone:

I have a shacking table simulation case. However, I have the test input acceleration record from tabletop records. The wave length is about 63 s, can the FEM input time history be scaled in terms of time to be shorter through a amplification factor like 0.5? then we will have a seismic wave with same acceleration values, but the time has been scaled. My idea is that "The input seismic wave data and the experimental test data don't need to be the same length"?

Thank you
