摘要

We present predictive models of cumulative absolute velocity (CAV), Arias intensity (I-A) and strong-motion duration (SD) by using a ground-motion database compiled from the broader European region. The same database was previously used to develop a set of pan-European ground-motion prediction equations (GMPEs) for 5-damped horizontal and vertical elastic spectral ordinates as well as for damping scaling factors to modify 5-damped spectral ordinates for a suite of damping values ranging from 1 to 50 (Akkar et al. in Bull Earthq Eng 12:517-547, 2014a; 1429-1430, 2014b; 359-387, 2014c; 389-390, 2014d). We present the CAV, I-A and SD predictive models together with the correlation coefficients to consider their interdependency with the spectral ordinates estimated by the 2014 horizontal Akkar et al. GMPEs. Thus, together with these new predictive models a consistent ground-motion modeling (including conditional and joint probability hazard) is now possible for a wide range of engineering problems (from liquefaction hazard to probabilistic loss modeling) in the pan-European region. As in the case of previous 2014 Akkar et al. GMPEs, the predictive models in this paper are valid for shallow active crustal regions with point- and extended-source distances < 200 km and moment magnitudes between 4 <= M-w <= 8. They are capable of representing soil conditions between 150 m/s <= V-S30 <= 1200 m/s.
