000010115 520__ $$2eng$$aSpatial distribution of ground motion data of recent earthquakes unveiled some features of peak ground acceleration (PGA) attenuation with respect to closest distance to the fault (R) that current predictive models may not effectively capture. As such, (1) PGA remains constant in the near-fault area, (2) may show an increase in amplitudes at distances of about 3-10 km from the fault-rupture, (3) attenuates with slope of 1/R and faster at farther distances, (4) and intensifies at certain distances due to basin effect (if basin is present). A new PGA attenuation model is based on records from shallow crustal earthquakes compiled in the Next Generation Attenuation (NGA) database with a number of additions from recent Californian and worldwide events. A novel feature of the predictive model is its new functional form structured on the transfer function of a single degree of freedom oscillator. In addition, a new PGA-based predictive model was developed for PGV and 5% damped pseudo spectral acceleration (SA) ordinates of free-field horizontal component of ground motion.
