Abstract

This paper presents an investigation into specific aspects related to the performance of reinforced concrete circular silos. Firstly, two case studies of recent failures in circular silos in the UK are described and significant observations are highlighted. Methods used for estimating internal horizontal pressures acting on silo walls are discussed, and recommended values of design parameters are compared. A brief account of the results of an analytical investigation, on typical silo configurations selected from the case studies, is also given. The study reflects the level of uncertainty in calculating internal pressures considering possible variability in the properties of stored material and silo walls. Additionally, an assessment of stresses induced in steel reinforcement and associated cracking in concrete within critical wall sections is summarized. Finally, the expected causes of observed damage in this type of structure are outlined. In particular, it is concluded that inadequate consideration of crack control and durability requirements increases the vulnerability of the structure and may lead to premature failures especially in the long term.
