摘要

This report presents an update to the Chiou and Youngs (2008a) NGA model for the prediction of horizontal peak ground acceleration and 5%-damped pseudo spectral acceleration for earthquakes in active tectonic regions such as California. The update is based on analysis of the greatly expanded NGA-West2 strong motion database. The updated model contains minor adjustments to the functional form developed by Chiou and Youngs (2008a) related to style of faulting effect, hanging wall scaling, scaling with the depth to the top of rupture, the effect of sediment depth, and the inclusion of two additional terms for the effects of fault dip and rupture directivity.
