Cracks in silo walls

Is it a must to repair and strengthen or even demolish silos if wide cracks are observed? This question might be best answered by means of an example of a reinforced multi-chamber raw meal silo. In this article a special case will be highlighted which may be of interest for many cement producers.

In general silos are structurally delicate structures. They consist of shell elements and can carry membrane tension or compression forces very well. However any bending moments or shear forces could lead to problems to the structural stability of the silo. In the given case the owner determined several extremely wide cracks in his unconventional multi-chamber raw meal silo during the regular inspection. A first expert opinion came with the result that the silo is under designed and must be strengthened with a heavy steel construction to regain structural stability. As the...
