Hello Everyone!

I am performing IDA analysis where I require the hazard curve as per IS 1893:2016 in the terms of The first column is the spectral acceleration in units of g while the second column is the mean annual frequency of exceedance.

Now, I have the data in the form of Time Vs. Spectral Acceleration(in terms of g).

Therefore, Can anyone help me out to convert the target spectrum data time Vs. spectral acceleration into mean annual frequency of exceedance vs. spectral acceleration?

Note that because of the hazard curve fitting in the log-log space, no values in the imported text file can be equal to zero.

Kindly suggest some technique.

Regard
