Also shown in this figure (if the ‘Display metadata’ option is<br />
selected in the ‘Options’ window) are the basic earthquake,<br />
waveform and station metadata of the selected time-history.<br />
Multiple time-histories selected<br />
Clicking on this button when multiple time-histories have been<br />
selected calculates and plots the drift spectra (e.g. Iwan, 1997)<br />
of the currently selected time-histories for the damping level<br />
and material type specified in the ‘Options’ window and<br />
displays them on the same graph so that they can be easily<br />
compared (see below).<br />
3.2.21 Comparisons<br />
Clicking on this button opens a new window (see below) that<br />
allows the user to compare the observed elastic response<br />
spectra of the selected time-histories with predicted median<br />
spectra from 21 recent GMPEs (e.g. Douglas, 2003) and three<br />
seismic design codes. The GMPEs that can be selected by<br />
clicking on the check-boxes are the following:<br />
