The results of a study that investigates potential revisions of the spectral shape factors used in standards in regions of low-to-moderate seismicity are presented here. Using an equivalent linear analysis, the investigation particularly focuses on the effects of seismic intensity associated with rare and very rare intraplate earthquake events on site response. The Pacific Earthquake Engineering Research Center ground motion database (PEER) is used in selecting appropriate acceleration-time histories for the intraplate region. The results are normalised for comparison with the current spectral shape factors given in the Australian Standards for Earthquake Actions AS 1170.4:2007, with some di..View full abstract
