In this Coffee Corner session, we'll explore the fundamentals and practical applications of Site Response Analysis. We'll begin with a brief overview of the theory and the classical Equivalent Linear Analysis in the frequency domain. The session will demonstrate how PLAXIS 2D can be applied for 1D Site Response Analysis, showcasing its ability to capture nonlinear soil behaviour. A comparison with a dedicated Equivalent Linear Analysis software will illustrate the strengths and limitations of each approach.

Learning Points:

Understand the basics of Site Response Analysis and its importance in geotechnical and seismic modelling. Learn how to perform 1D Site Response Analysis using PLAXIS in a practical workflow. Compare different material models in PLAXIS (HSsmall and GHS for small-strain stiffness) for 1D site response scenarios. Recognise the advantages of PLAXIS over traditional equivalent linear methods for advanced seismic analyses.
