Abstract: Silos are special structures subjected to many different unconventional loading conditions, which result in unusual failure
modes. Failure of a silo can be devastating as it can result in loss of the container, contamination of the material it contains, loss of
material, cleanup, replacement costs, environmental damage, and possible injury or loss of life. Silo damage and failures that occurred in
different regions of the world are presented in the paper using illustrative photos. Also provided are a review and discussion of the
common or spectacular silo failures due to explosion and bursting, asymmetrical loads created during filling or discharging, large and
nonuniform soil pressure, corrosion of metal silos, deterioration of concrete silos due to silage acids, internal structural collapse, and
thermal ratcheting. Silo damage and failures from several earthquakes are also presented.
