Currently the accelerations of the spectrum etc. are defined and evaluated at the frequencies which are spaced linearly over preferred period range. ASCE 43-05 2.4 (b) (which is quoted in ASCE 4-16 as well) requires: "Spectral accelerations ... shall be computed at minimum of 100 points per fre...

Thank you Hufte. You are absolutely right. In the KTA 2201.1 standard chapter 4.3.3 (2) the same idea has been stated more clearly and it's easy to adapt for the individual spectrum: "Time histories shall be considered as compatible with the ground acceleration response spectrum detailed in Sec...

Thank you! I'l give a try now.

It seems that SeismoArtif constantly produces acceleration histories which doesn't fit into +-10 % allowable range when compared to target spectrum, but still states that convergence has been archived. In practice this is probably not an issue, but for example ASCE 4-98 states that any point of the ...

I would like to have possibility to use frequency unit (Hz or 1/s) in the abscissae axis of the spectrums instead of period (s). I just feel it more informative.
