Ground Motion Accelerograms for Nonlinear Time History Analysis in Low-to-Moderate Seismicity Regions

Abstract

This paper is concerned with selecting and scaling records of earthquake ground motion acceleration time histories for use in southeastern Australia which is used as an example to illustrate the application of the Conditional Mean Spectra (CMS) methodology in a low to moderate seismicity region. The study involved making use of a diversity of Ground Motion Prediction Equations (GMPEs) along with a recently developed regional-adjustable Component Attenuation Model (CAM) which takes into account effects of the regional crustal profile on ground motion behavior. When applying the GMPEs to construct the CMS for bedrock conditions three different combinations of weighting factors were adopted to ..
