Site-Specific Response Spectra and Accelerograms on Bedrock and Soil Surface

This paper is aimed at serving the needs of structural engineering researchers who are seeking accelerograms that realistically represent time histories earthquake ground in support their own investigations. Every record identified with a specific scenario defined by magnitude–distance combination and site conditions; intensity presented records consistent ultimate limit state design requirements for important structures an intraplate region. Presented this article were generated on soil surface two example class Ce sites De based response analyses respective column models utilizing bedrock excitations as derived from conditional mean spectrum (CMS) methodology. The CMS developed rock matching code model stipulated Australian standard seismic actions Be reference periods 0.2, 0.5, 1 2 s return ranging 500 to 2500 years. regulatory documents does not preclude adoption materials applications outside Australia. To reduce modeling uncertainties, simulation motion interest information provided borelogs. site-specific strong separate CMS-based accelerogram selection–scaling obtaining (utilizing data PEER). decoupling processes departure use has merit reducing uncertainties achieving more realistic representation actions.
