| Abstract: | In this paper, the behaviour of a real geogrids reinforced embankment will be analysed based on the results of numeric modelling
in seismic conditions. The reinforced slope is analysed using commercial software based on the finite differences method.
After the program presentation, is described the methodology of analysis. In modelling, will be devoted special relevance
to the behaviour of the structures in terms of deformations, using comparative analyses with different damping ratio values
for soils and for reinforcements. Finally, will be drawn some conclusions concerning the behaviour of reinforced structures
and in particular, the role of the structural reinforcement’s damping. |
