Ovalization of Steel Storage Tanks as a Result of Differential Settlements

In this paper, the effects induced by the differential settlements in open top and floating roof steel storage tanks are analysed. Attention is focused on the ovalization induced by the radial movements of the wall which may reach relevant amplification in comparison with the differential settlement...

Description
Summary:In this paper, the effects induced by the differential settlements in open top and floating roof steel storage tanks are analysed. Attention is focused on the ovalization induced by the radial movements of the wall which may reach relevant amplification in comparison with the differential settlement values. Simplified interpretative models and correlations useful in the analysis of the structural behaviour are also presented.
