Abstract
A database consisting of 78 horizontal strong ground motion records from a single earthquake, the U.S. Loma Prieta earthquake of Oct. 17, 1989, has been considered to study the statistical relationship of duration of strong ground motion with several parameters associated with the characteristics of an earthquake record. These parameters are: 1) distance from the source of energy, 2) root-mean-square (rms) value of the acceleration record, 3) frequency content of the record, and 4) the mean response spectral values. Three different definitions were adopted for extracting the strong ground motion duration — the “bracketed” duration, the “accelerogram intensity,” and the “energy arrival rate” definitions. Results are reported for two geological groups namely, rock and alluvium.
