NGA-East: Median Ground-Motion Models for the Central and Eastern North America Region, PEER Report 2015-04

2015

This report documents recent ground motion models (GMMs) developed as part of the Next Generation Attenuation for Central and Eastern North America (CENA) project (NGA-East). NGA-East is a multi-disciplinary research project coordinated by the Pacific Earthquake Engineering Research Center (PEER) that involves a large number of participating junior and senior researchers, practitioners, and end-users. Various organizations have provided technical input to the project from academia, industry, and government agencies. The objective of NGA- East is to develop a new ground motion...

Adjusting Ground-Motion Intensity Measures to a Reference Site for which V(S30) = 3000 m/sec, PEER Report 2015-06

David M. Boore
2015

Adjustment factors that can used to convert ground-motion intensity measures at sites with VS30=760 m/sec and VS30=2000 m/sec to a reference rock site, defined as one with VS30=3000 m/sec, are provided as tables: (1) for moment magnitudes from 2 to 8; (2) rupture distances from 2 km to 1200 km; (3) response spectra at periods from 0.01 sec to 10.0 sec; and (4) peak acceleration and peak velocity. Ten velocity models used in ground-motion studies in central and eastern North America with VS30 values very close to 760 m/sec were considered,...

NGA-East: Ground-Motion Standard Deviation Models for Central and Eastern North America, PEER Reports 2015-07

Linda Al Atik
2015

Empirical ground-motion data from Central and Eastern North America (CENA) are used to analyze the components of ground-motion variability in CENA. Trends of ground-motion variability with parameters such as magnitude, distance, and VS30 are analyzed and compared to trends of ground-motion variability in other regions, particularly the Western United States (WUS) using the NGA-West2 dataset.

The CENA dataset is limited in magnitude range to small-to-moderate magnitudes and in frequency content to frequencies between 1 and 10 Hz due to the bandwidth limitations of the recordings....
