The NGA-Subduction site database, which is currently in development, contains information on site condition and instrument housing for 5520 strong motion stations with re [...]

A ground motion model (GMM) was developed for the vertical-to-horizontal (V/H) ratio of 5%-damped elastic response spectra at periods ranging from 0.01 to 10 sec. The V/H [...]

Electric equipment qualification is generally based on shake-table tests that use generic response spectra as the target intensity measure for the ground motions used. Th [...]

NGA-Subduction is a large multidisciplinary, multi-year research program to develop database resources and ground motion models (GMMs) for subduction-zone earthquakes. Co [...]

This paper presents a mathematical formulation that directly estimates the engineering demand parameters (EDPs) of moment-resisting frames based on structural characteris [...]

Several west coast cities are seeing an upsurge in the construction of high-rise buildings. Many of these buildings feature framing systems, materials, heights, and dynam [...]

A recently developed nonstationary stochastic model of strong earthquake ground motion is described. The model employs filtering of a white-noise process, where nonstatio [...]

We present a new empirical ground motion model for PGA, PGV, PGD and 5% damped linear elastic response spectra for periods ranging from 0.01–10 s. The model was develop [...]

In this paper we present results of direct probabilistic and deterministic hazard analyses of inelastic response spectra. Inelastic response spectra of over 3100 horizont [...]
