A Compact Probabilistic Representation of the Chi-Chi Earthquake Ground Motion - Reinforced Soil Engineering: Advances in Research and Practice - page 476

ensemble excitation process. The “exact” curve is computed by numerically integrating
the response for each of the input records, and the dashed estimate curve is obtained
through the analytical approximation technique.
determined and subsequently used to obtain the nonstationarymean-square response
of linear systems. It is shown that this chapter's approach provides a useful tool for
drastic data condensation in a probabilistic format that allows analytical
determination of the transient response of structural systems, thus leading to the
development of regional probabilistic response spectra. The authors are currently
working on a more extensive study utilizing as many data-based ground motion
recordings from the Chi-Chi event and its aftershocks as possible.
