Structural behavior of stiffened steel silos subject to eccentric discharge pressures
Thin-walled cylindrical steel silos are extensively used in many industries and agricultural sectors for storing materials. Eccentric discharge is widely recognized as the most severe load case for steel silos. Accordingly, this paper aims to present the results of a finite element analysis of the buckling strength of stiffened cylindrical silos during eccentric discharge under different pressure distribution proposals. The distribution patterns of Eurocode may lead to the lowest buckling loads. Subsequently, an extensive parametric analysis is carried out to verify the influence of various factors on the buckling behavior of the stiffened silo under eccentric discharge. Ultimately, based on the buckling stress design method of Eurocode, combined with parametric and regression analyses, the simple formula for calculating the stiffened steel silo buckling resistance is proposed.
期刊介绍:
The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
