Wooddell, and Robert R. Darragh, Jonathan P. Shahi and Jack W. Skip to main content. Modern approaches to assessing seismic performance of infrastructure rely on good information about likely ground shaking at a site. Darragh, Jonathan P. Wooddell, Robert W. Throughout the project there will be various public workshops to solicit feedback and advice from various stakeholders and future users of the attenuation models. The first step was to collect the most important ground motion records worldwide.
This NGA-West2 project follows-up on and extends work completed in a previous program, NGA-West which was successfully coordinated by PEER and. The Pacific Earthquake Engineering Research Center (PEER) is a nine-campus The NGA-West2 ground motion database includes a very large set of ground.
The NGA West2 program is a followup to the original NGA program and will be The PEER NGA West project resulted in a major improvement in the prediction.
The results of this program are expected to be of great interest to the earthquake engineering community, as it is expected that the improved models will be reviewed by USGS for consideration in future updates of the United States National Seismic Hazard Maps and incorporation in the building code. Stewart and Emel Seyhan — Report 3.
The new NGA-West2 project addresses several important issues in earthquake engineering, including modeling of directivity and directionality; verification of NGA-West models for recent small, moderate and large magnitude events; scaling of ground motion prediction equations GMPE for different levels of damping; development of GMPEs for vertical ground motion; treatment of epistemic uncertainty; and evaluation of soil amplification factors in NGA models versus NEHRP site factors.
NGA-East was jointly sponsored by the U. Various enhancements to the database have been made in recent years, and the latest version of the database can be found at the top of this web page. Chiou, Katie E. Wooddell, and Robert R.

The database contains over 29, records from 81 earthquake events and recording stations. Stewart, Katie E. Graves, Albert R. Kottke, David M.
Pacific Earthquake Engineering Research Center (PEER) is pleased to announce the release of an updated and enhanced PEER NGA-West2 Online Ground.
The database and web site are periodically updated and expanded.

Silva, Youssef M. The following step was to gather related metadata such as earthquake magnitude, various site-to-source distance measures, style of faulting, local site conditions at the recording stations, and other relevant engineering parameters.

SUMMARY. The NGA-West 2 project database expands on the current PEER NGA ground-motion database to include worldwide ground-motion data recorded.
regions (NGA-West2) is an on-going research program to address several peer-reviewed ground motion prediction equations, GMPEs (Power et al., ).

The user of the databases, flatfiles, models, and reports assumes the entire responsibility of using them. Chiou, Badie Rowshandel, Shrey K. Wooddell, Robert W. Chiou and Robert R.
