Conversion of response spectrum to acc time history with Matlab
Conversion of response spectrum to acc time history with Matlab
(OP)
Hello.
Could anybody help me with my problem? I have response spectrum of acceleration and I would like to get acceleration time-history with the same properties as were used for computation of my response spectrum. I was looking for it in the Internet, but no idea how to perfrom this with matlab. I need to do that in matlab. I have basic experience with matlab and this is for me really difficult. Please help me, if someone knows more about it. Thanks.

Depending on what you are trying to do then you can generate a random phase spectrum, turn the pair of spectra into complex numbers and then IFFT it.
