This report documents the development of the NGA-West2 empirical ground-motion prediction equations (GMPEs) for ground-motion intensity measures derived from recordings of the vertical component of ground motion. The extensive and expanded PEER NGA-West2 ground-motion database recorded from shallow crustal earthqua kes in active tectonic domains was used to develop GMPEs for the vertical component of peak ground acceleration (PGA), peak ground velocity (PGV), and 5%-damped elastic pseudo-absolute acceleration response spectral ordinates (PSA) at periods ranging from 0.01 to 3 sec (the NGA-West2 consensus period range for vertical component).
Other research products and findings of the NGA-West2 project, including the development of a comprehensive database of ground motion recorded worldwide and development of GMPEs for horizontal components, have been published in a series of reports by the Pacific Earthquake Engineering Research Cent er (PEER). The focus of this report is on vertical ground motion. Since the NGA-West2 database and numerous NGA-West2 PEER reports have already been published and can be referenced, the consensus of the NGA-West2 GMPE developers was that for vertical ground motion a single PEER report with independent chapters authored by different NGA-West2 GMPE developers would be published. Each chapter of this report explains the details of a speci fic GMPE for vertical component developed by a specific ground-motion model developer team.
