Hey There. I am kinda lost. What is the unit of Fourier amplitude, calculated by SeismoSignal? My understanding is that the said unit should be g.s, meaning that Fourier amplitude times the frequency should give the corresponding value of Sa (g).

How would the fictitious response spectrum be defined, rich in the low frequencies (high periods), believed to be representative of a near-field event?

What is the use of the mean matched spectrum?

Thanks a bunch, Zoi.

Hey There! Is it possible to get the acceleration record from the mean matched spectrum? If so, how?

Could you please help me out with matching the yellow response spectrum to the red one as the seed response spectrum? It should be voiced that I have been playing with the Min and Max periods; yet, it went haywire!!!

I will defo go through the references; nonetheless, is there any chance that I would have a reference spelling out the said method in plain language inasmuch as I am in the middle of prepping a report having a strict deadline?

Thanks heaps

Making a comparison between the original and matched acceleration records would defo reveal a shift in the PGA time. How is the said shift supposed to be explained using the response spectrum matching procedure?

Thanks a bunch!

What is the meaning of the non-zero power amplitude and Fourier amplitude at zero frequency when truncating an earthquake acceleration record? It is of appreciation if you could demystify the rationale behind the aforesaid non-zero values plus the way which otta be utilized to set them back to zero ...

The issue, which I have sent to support@seismosoft.com, is that SeismoMatch does not display the values for the matched acceleration record and response spectrum thereunto on a regular basis, despite the fact that the said software has been reinstalled!

Thanks heaps, Zoi!
