PEER Lifelines Program
Interim Reports of Next Generation Attenuation (NGA) Models
Interim reports of NGA models are provided on the PEER web site for review and trial use. Additional reports will be added to the website as they are completed.
The NGA ground motion models are subject to further evaluation by the authors and are undergoing external review and changes may be made as a result of this process. Use of the NGA models for any purpose is the sole responsibility of the user.
Incorporation of directivity effects in the models is under development and not yet implemented.
Questions and review comments on the NGA models are welcome and can be addressed directly to the authors (copy to Dr. Yousef Bozorgnia of PEER, Email: Yousef@Berkeley.edu).
