Vector Valued

In this study, various alternative vector-valued ground motion intensity measures (IMs) are used to estimate maximum inter-story drifts and hysteretic energy demands of steel framed buildings under long duration narrow-band ground motions. The vectors are based on the spectral acceleration at first mode of the structure as first parameterSa (T1). As the second parameter of the vector,IMsrelated to peak, integral and spectral shape parameters are selected. It is concluded that spectral-shape-based vector-valuedIMshave the best relation with maximum inter-story drift and energy demands in steel frames subjected to narrow-band earthquake ground motions.

The Impact

This study examines the statistical correlation between the spectral accelerations of mainshock-aftershock ground motion pairs in the NGA-West2 ground motion database. Aftershock spectral accelerations are found mildly correlated with their mainshock counterparts for closely spaced periods of vibration and are weakly correlated over the rest of the period range. We further investigate for potential differences between the interperiod correlations of mainshock and aftershock spectral accelerations, finding no substantial evidence to support the use of different models for the two cases. Furthermore, the impact of different rupture scenario parameters on correlation is examined and discussed. The derived correlation estimates are expected to aid in aftershock seismic hazard assessment and/or in record selection for risk assessment applications by using the mainshock spectral ordinates to obtain better predictions for the aftershock ground motion.
