• Abstract:
  Ground motions in close proximity to the causative fault of an earthquake can be significantly affected by the propagation of ; rupture. In particular, when the rupture and slip direction relative to a site coincide and a significant portion of the fault ruptures ; towards the site, the ground motion can exhibit the effects of Forward-Directivity (FD). Forward-directivity effects can result in ; higher seismic demands and must be considered for design or retrofit of a structure that is in the proximity of an active fault. Much ; research has been conducted recently on the seismological aspects leading to forward-directivity, the characteristics of FD motions. ; However, designers still lack specific guidelines as to how to account for FD effects when determining the seismic hazard for a given ; structure. ; The overall purpose of this research project is to develop a methodology for the inclusion of the effects of near-fault forwarddirectivity ; into the determination of seismic demand for a structure or a geotechnical system. The focus of the study will be the ; potential for near-fault effects associated with the Seattle and Tacoma faults in Washington State, and how these near-fault effects can ; affect the transportation infrastructure in the state.
