Methods to account for near-fault rupture directivity effects in the development of ground motions for seismic design are described. These effects, due to propagation of the rupture toward the recording site and to fault slip occurring in the direction toward the site, cause a long period pulse of motion in the normal direction to the fault that occurs near the beginning of the record. In order to facilitate the selection of time histories that represent near-fault ground motion conditions in an appropriate manner, a list of near fault records indicating the nature of the rupture directivity effects is provided.
