Generation of Site-Specific Accelerograms and Response Spectra Involving Sampling Information from Borehole Records

This paper is aimed at serving the needs of structural engineering designers an important structure (or a group structures located on same site) who seeking guidance how to obtain accelerograms and/or derive response spectra that accurately represent site subsoil conditions as informed by borelogs. The presented site-specific seismic action model may be used replace default stipulated for designated class. Presented in this article procedure generating soil surface motions earthquake, and their associated spectra, taking into account details layers. Dynamic analyses are involved. conditional mean spectrum methodology employed selecting scaling obtaining input motion bedrock. selection depends natural period both structure. Multiple borelogs taken from within analysed identify critical column models without having conduct analysis every borelog. technique simplifying layers utilising shear strain profile introduced further cut down time analyses. procedures described have been written web-based program freely accessible practitioners.
