Abstract
This dataset provides the Cumulative Absolute Velocity (CAV) table for the NGA-West2 records. Each record is identified by the RSN key, which corresponds to the identical key in the NGA-West2 Database (Ancheta TD, Darragh RB, Stewart JP, et al. NGA-West2 Database. Earthquake Spectra. 2014;30(3):989-1005. doi:10.1193/070913EQS197M).
More detailed information about the NGA-West2 database can also be found in PEER 2013/03 – PEER NGA-West2 Database , by: Timothy D. Ancheta, Robert B. Darragh, Jonathan P. Stewart, Emel Seyhan, Walter J. Silva, Brian S.J. Chiou, Katie E. Wooddell, Robert W. Graves, Albert R. Kottke, David M. Boore, Tadahiro Kishida, and Jennifer L. Donahue (https://apps.peer.berkeley.edu/publications/peer_reports/reports_2013/webPEER-2013-03-Ancheta.pdf).
The Cumulative Absolute Velocity (CAV) was computed using the method proposed by Campbell and Bozorgnia in 2012 (Earthquake Spectra, Volume 28, No. 2, pages 457–485, May 2012; © 2012, Earthquake Engineering Research Institute). CAV is defined as the integral of the absolute value of acceleration for the total duration of the ground-motion record. The standardized version of CAV, CAV_STD, also included in the data table, prevents low-amplitude, non-damaging ground motions from contributing to the value of CAV. CAV values were computed for all three components of ground motion, where available.
