Dynamically Loaded Anchorages

The present work regards the study of soil-structure interaction, in particular during pull-out tests on anchorages. Due to the complexity of the system, numerical analyses carried out by a commercial code, based on the Finite Difference Method (FDM), were performed. In order to calibrate the overall selected approach, first of all, a simple two-dimensional model of the system was firstly study. The preliminary results and suggestions for incoming 3D modeling improvements are discussed. Furthermore attention has been focused on the nature of the impulsive impacting force due to a virtual debris flow or avalanches striking on the structure, including the anchorages, in order to correctly simulate the test of pull out. Accordingly, a simplified, preliminary model of the anchorages-net system, including the effect of the mass deposition, is proposed and discussed.
