Evaluation of the Shape of Ieee-693 Response Spectra for Subduction and Crustal Earthquakes
Abstract eng: Electric equipment qualification is generally based on shake-table tests that use generic response spectra as the target intensity measure for the ground motions used. These response spectra are specified as part of IEEE-693 recommendations and intended to reasonably envelope anticipated earthquakes. The objective of this paper is to investigate the applicability of, and possible adjustments needed for, the IEEE-693 generic response spectra for subduction events. A parametric study of earthquake scenarios demonstrated that the enveloping spectral shapes are dependent on both the event type and the level of intensity of the scenarios. Crustal-event scenarios as well as intra-slab and interface event scenarios were evaluated. The main difference in spectral shape for these types of events was found at the short-period range below one second.
