Validation by centrifuge testing of numerical simulations for soil-foundation-structure systems

Abstract

In this paper, an attempt is made to validate the numerical response of a soil-structure system with observations from physical modeling, using data from high gravity centrifuge testing that have been carried out on portal frames founded on uniform soil strata. The preliminary conclusions drawn by the comparative evaluation of numerical and physical testing are related to: a) the identification of the assumptions and system modifications required to achieve an acceptable level of matching between numerical and experimental results, b) an overview of the numerical results in terms and the dynamic response of soil-structure systems
