1. Project Goals/Objectives:

Configure the PEER Strong Motion Data Set for use in developing empirical attenuation relations. This process involves updating and adding metadata (earthquake source, wave propagation path, and site parameters), adding new earthquakes/sites in terms of metadata as well as motions, and providing an independent checking or review process. A subset of the metadata considered as potential dependent or independent parameters along with peak values of acceleration, velocity, and displacement as well as 5% damped response spectral ordinates will be accumulated in a single “flat” file for ease of use in regression analyses.

2. Role of this project in supporting PEER’s mission (vision):

Database is critical input to several PEER projects. It will form the basis for the PEER NGA effort.

3. Methodology Employed:


4. Brief Description of past year’s accomplishments (Year 6) & more detail on expected Year 7 accomplishments:

Single Year Project.

5. Other Similar Work Being Conducted Within and Outside PEER and How This Project Differs:

Unique Project.

6. Plans for Year 8 if project is expected to be continued:


7. Describe any actual instances where you are aware your results have been used in industry:

PEER projects that use the data sets will have major impacts on seismic hazard industry. New attenuation relations from the PEER NGA project will be used by industry and academics.

8. Expected Milestones & Deliverables:

Data sets to be completed by 8/1/03.
