components are selected. Also, some GMPEs are for specific
site conditions (e.g. rock) and therefore no predictions are
displayed if the selected time-histories were recorded at sites
with different conditions. The user is encouraged to study the
original references [or the summaries by Douglas (2004, 2006,
2008)] for the limits of validity of the models and for which
metadata are required.

The seismic design codes that can be selected are the
following:

1. Eurocode 8 (European Committee for Standardization,

2002) (EC8);

2. Uniform Building Code 1997 (International Conference of

Building Officials, 1997) (UBC1997);

3. International Building Code 2000 (International Code

Council, 2000) (IBC2000).

UBC1997 and IBC2000 do not provide predictions for vertical
spectra and so these are not displayed if the time-histories
selected are for the vertical component. The user is
encouraged to study these references for the limits of the
validity of these seismic design code spectra.

Once the user has selected the GMPEs and the codes to
compare with the observed elastic response spectra for the
selected time-histories (and, if a seismic design code has been
