“…Five [Atkinson and Boore, 2003, Crouse, 1991, García et al, 2005, Lin and Lee, 2008, McVerry et al, 2006 out of the eight selected models are ranked in the lowest capability class (D) by the method of Scherbaum et al [2004] and only one model, that of Kanno et al [2006], is ranked higher than C. The results for the GMPEs of Atkinson and Boore [2003], Crouse [1991] and Youngs et al [1997] are in agreement with those presented by Douglas et al [2006] based on their smaller dataset.…”

“…All the selected models underestimate the groundmotion variability observed in the Lesser Antilles (shown by values of STDNR greater than unity) although for the models of Kanno et al [2006] and Youngs et al [1997] this underestimation of the variability is small (in fact, these models predict larger variabilities for intraslab events than observed). As discussed by Douglas et al [2006] the reasons for the apparently poor match between predictions and observations could be partly due to an observational dataset from a different magnitude and distance range than used by the developers of the selected GMPEs.…”

“…Recorded ground motions from the selected subduction earthquakes (see Table 3 Youngs et al [1997] and Zhao et al [2006]. Atkinson and Boore [2003] have combined the datasets of Crouse [1991] and Youngs et al [1997] and also have added much additional data therefore the equations of Atkinson and Boore [2003] could be thought to have superseded the equations of Crouse [1991] and Youngs et al [1997].…”

The equations of Crouse [1991] and Youngs et al [1997] have been included here since they have often been used for seismic hazard assessments of the Antilles and therefore it is important to check their validity. All selected models use moment magnitude.…”

“…For subduction earthquakes (both interface and intraslab) Douglas et al [2006] considered three often-used models developed using data from subduction zones worldwide: Atkinson and Boore [2003], Crouse [1991] and Youngs et al [1997], and found that the model of Youngs et al [1997] predicts reasonably well earthquake ground motions recorded on the French Antilles but the other two models poorly predict such motions. The majority of the records used by Douglas et al [2006] for subduction earthquakes were from interface events: 91 records from eleven interface earthquakes compared to 56 records from three intraslab earthquakes.…”

This brief article presents a quantitative analysis of the ability of eight published empirical ground-motion prediction equations (GMPEs) for subduction earthquakes (interface and intraslab) to estimate observed earthquake ground motions on the islands of the Lesser Antilles (specifically Guadeloupe, Martinique, Trinidad and Dominica). In total, over 300 records from 22 earthquakes from various seismic networks are used within the analysis. It is found that most of the GMPEs tested perform poorly, which is mainly due to a larger variability in the observed ground motions than predicted by the GMPEs, although two recent GMPEs derived using Japanese strong-motion data provide reasonably good predictions. Analyzing separately the interface and intraslab events does not significant modify the results. Therefore, it is concluded that seismic hazard assessments for this region should use a variety of GMPEs in order to capture this large epistemic uncertainty in earthquake ground-motion prediction for the Lesser Antilles.

Ground response analysis of Bahlui Clay as a foundation layer

et al. 2018

View full text Add to dashboard Cite

The purpose is to evaluate ground response of 30 m soil column subjected to different seismic actions. The main foundation layer under investigation is a fat clay specific for Iasi, the Bahlui clay. Three main investigation steps have been followed. The first one consists in laboratory tests using resonant column and torsional shear tests only for Bahlui clay. Degradation curve has been established for both shear modulus and damping ratio. Dynamic parameters of the other layers have been established using empirical models. The second step consists of determination of the site's response spectrum. Equivalent linear one‐dimension analysis using STRATA software has been performed in order to determine the seismic response of the soil column. The analysis results highlight an amplified seismic input motion associated with each soil layer type. They will lead to a better understanding and will improve the characterization of the site response effects, necessary for the local engineers to manage the design of new constructions and to properly consolidate the existing ones.

Regional variation of spectral parameters for seismic design from broadband probabilistic seismic hazard analysis

SummaryThe characterisation of the seismic hazard input is a critical element of any seismic design code, not only in terms of the absolute levels of ground motion considered but also of the shape of the design spectrum. In the case of Europe, future revisions of the seismic design provisions, both at a national and a pan‐European level, may implement considerable modifications to the existing provisions in light of recent seismic hazard models, such as the 2013 European Seismic Hazard Model. Constraint of the shape of the long‐period design spectrum from seismic hazard estimates on such a scale has not been possible, however, owing to the limited spectral period range of existing ground motion models. Building upon recent developments in ground motion modelling, the 2013 European Seismic Hazard Model is adapted here with a new ground motion logic tree to provide a broadband Probabilistic Seismic Hazard Analysis for rock sites across a spectral period range from 0.05 seconds to 10.0 seconds. The resulting uniform hazard spectra (UHS) are compared against existing results for European and broadband Probabilistic Seismic Hazard Analysis and against a proposed formulation of a generalised design spectrum in which controlling parameters can be optimised to best fit the uniform hazard spectra in order to demonstrate their variability on a European scale. Significant variations in the controlling parameters of the design spectrum are seen both across and within stable and active regions. These trends can help guide recalibrations of the code spectra in future revisions to seismic design codes, particularly for the longer‐period displacement spectrum.
