Numerical and experimental soil-structure-interaction of a bridge pier model at the Volvi-Greece European Test Site

摘要

This paper presents the experimental and numerical actions that have taken place within the context of the preparation of the man-made excitations of a model bridge pier which is constructed at the Volvi -Greece European Test Site for the study of the dynamic pier-foundation-soil system interaction. In particular, a set of in-situ low level dynamic tests have been performed which were complemented by laboratory tests and preliminary finite element analysis in order to optimize the design of the structure towards the maximization of the SSI effects while retaining the system within the available force level capabilities that can be applied on site. Both experimental and numerical results have contributed to the optimal design of the structure and the preliminary prediction of its dynamic behavior.
