Comparison for Different Circumferential Weld-Induced Imperfections on Steel Silos

Abstract:

As the thin-walled structure,the buckling of steel silos is very sensitive to the initial geometric imperfections. However, these imperfections are uncertain to the shape and amplitude, so the studies of the initial geometric imperfections have important practical significance. Over the years, the circumferential imperfections have been known to result in the most important influence on the buckling of steel silos, which is also the most common defect in practical engineering. Using the existing research results, this paper analyzes three different imperfection shape functions and compare to the result of experiment in order to identify a function for the finite element analysis.
