ASCE7-22 via NEHRP-2020 : Smooth out “squigglies” in 2-period spectra
The USGS web service (but not the "USGS Seismic Design Geodatabase") originally provided the 2-period spectra early in the update cycle for at least comparison purposes, but I'm hearing that continuing to do so might be resulting in them being used for more than was intended and, hence, perhaps the USGS web service (and thereby the ASCE 7 Hazard Tool) should no longer provide the 2-period spectrum?
Alternatively, perhaps the 2-period spectra could be provided at periods corresponding to the rounded spectral acceleration values, with enough precision of the periods to do so? I'd really hesitate to provide more precise spectral accelerations for the 2-period spectra than for the multi-period spectra, the precision of which was decided with the PUC. But I wouldn't mind providing more precise period values.
