Abstract
Ratios of pseudo‐spectral velocity (averaged over the period range of 0.5–2 seconds and at a period of 1 second) to peak ground velocity (PGV) were computed for hundreds of ground motion records selected from the PEER NGA Strong Motion Database. Two‐stage regression analyses were performed to develop models for the ratios. The inter‐event terms of the ratios trend to moderate decrease as moment magnitude increases; the intra‐event residuals do not depend on distance. The results of this study provide the technical basis for a procedure presented in the American Technology Council's ATC‐58 project, Guidelines for Seismic Performance Assessment of Buildings , for estimating PGV by scaling values of pseudo‐spectral velocity.
