Electronic Supplement to
Empirical Improvements for Estimating Earthquake Response Spectra with Random-Vibration Theory
by
David M. Boore and Eric M. Thompson
This Electronic Supplement contains links to files used by the SMSIM software in simulating the ground motions
for the various cases discussed in the text. In addition, a table is given with information about the model used for each figure,
and additional figures illustrating models not given in the text, for western North America, are provided. A table containing abbreviations used in this
electronic supplement is also given (the abbreviations are also defined in the text).
Tables.
- Table S1.A table of definitions used in this electronic
supplement.
- Table S2.A table listing the model, low-cut filter corner,
and equation used to compute D_{rms} for the following figures for WNA parameters.
The table is given as a comma separated variable file for easy importation into spreadsheet programs.
The SMSIM parameter files (with "params" as the file extension) for the two ENA and two WNA models, as well as tables
containing coefficients for equation (10) in the text,
are in the zip file smsim_input_files.zip. The coefficients were derived from
the ENA and the WNA SCF models with no low-cut filter.
The files are in ascii format.
The parameter files
are for single corner frequency source spectra("SCF" in the file names) and
double corner frequency source spectra ("AB95" and "AS00" in the file names)
for ENA and WNA. All parameter files include the names for the files containing the
BT12 coefficients for D_{rms} (the particular set of coefficients or combination of coefficients
is indicated by the last entry in the "!rv params:" parameters input line).
