“…Generally speaking, ground motion models are an empirical relationship characterizing the correlation between earthquake ground motion (e.g., PGA) and earthquake magnitude and source-to-site distance combined. In Taiwan, several ground motion models were developed with earthquake data around the region [21,22], and used in recent seismic hazard assessments [2,3,21]. In the following seismic hazard analysis, we also adopted a local ground motion model that was frequently used in earthquake analyses for Taiwan [2,3,21], as follows:…”

“…Considering this subduction attenu- ation relation is incompatible with the NGA database which primarily contains records from shallow crustal earthquakes, the model is not adopted in the current study. In contrast, the recent GMPE developed by Lin et al (2011) is capable of predicting PGA and response spectra for periods ranging from 0.01 to 5 s, and therefore it is adopted in this study to develop the target response spectra for selecting earthquake time histories. The function form of the adopted model ) is expressed as follows:…”

“…It is agreeable that the worst-case scenarios considered in this paper may not be the hanging-wall case. However, since the Lin et al (2011) model is the only available regional-specific response spectral attenuation model for shallow crustal earthquakes to the authors' best knowledge, this hanging-wall attenuation model is adopted in the current study to construct the target response spectra with reasonably conservative results provided. It is also worth noting that we only employ the local ground-motion model in this study.…”

Abstract. In performance-based seismic design, groundmotion time histories are needed for analyzing dynamic responses of nonlinear structural systems. However, the number of ground-motion data at design level is often limited. In order to analyze seismic performance of structures, ground-motion time histories need to be either selected from recorded strong-motion database or numerically simulated using stochastic approaches. In this paper, a detailed procedure to select proper acceleration time histories from the Next Generation Attenuation (NGA) database for several cities in Taiwan is presented. Target response spectra are initially determined based on a local ground-motion prediction equation under representative deterministic seismic hazard analyses. Then several suites of ground motions are selected for these cities using the Design Ground Motion Library (DGML), a recently proposed interactive ground-motion selection tool. The selected time histories are representatives of the regional seismic hazard and should be beneficial to earthquake studies when comprehensive seismic hazard assessments and site investigations are unavailable. Note that this method is also applicable to site-specific motion selections with the target spectra near the ground surface considering the site effect.

“…For example, an earthquake catalog complied by the Central Weather Bureau Taiwan is on an M L basis (e.g., Wang et al, 2011). On the other hand, moment magnitude M w that is not subject to the so-called magnitude saturation is commonly adopted in the developments of ground motion models, for a more precise ground motion prediction (Wu et al, 2001;Campbell and Bozorgnia, 2008;Lin et al, 2011).…”

Abstract. Earthquake size can be described with different magnitudes for different purposes. For example, local magnitude M L is usually adopted to compile an earthquake catalog, and moment magnitude M w is often prescribed by a ground motion model. Understandably, when inconsistent units are encountered in an earthquake analysis, magnitude conversion needs to be performed beforehand. However, the conversion is not expected at full certainty owing to the model error of empirical relationships. This paper introduces a novel first-order second-moment (FOSM) calculation to estimate the annual rate of earthquake motion (or seismic hazard) on a probabilistic basis, including the consideration of the uncertain magnitude conversion and three other sources of earthquake uncertainties. In addition to the methodology, this novel FOSM application to engineering seismology is demonstrated in this paper with a case study. With a local ground motion model, magnitude conversion relationship and earthquake catalog, the analysis shows that the best-estimate annual rate of peak ground acceleration (PGA) greater than 0.18 g (induced by earthquakes) is 0.002 per year at a site in Taipei, given the uncertainties of magnitude conversion, earthquake size, earthquake location, and motion attenuation.
