This study investigates the seismic response of elevated silos and tanks, by means of Incremental Dynamic Analysis (IDA) methodology. Different kinds of Finite Element Models (FEM) have been performed, using the commercial code Straus7.

A complete FE model made of bricks elements and a simpler FE model with distributed masses on the silo walls have been implemented.

The results are compared with particular attention on the failure modes, and collapse behaviour.
