Buckling strength of the cylindrical shell and tank subjected to axially compressive loads

摘要

This paper aims to develop practical design equations and charts estimating the buckling strength of the cylindrical shell and tank subjected to axially compressive loads. Both geometri- cally perfect and imperfect shells and tanks are studied. Numerical analysis is used to evaluate buckling strength. The modeling method, appropriate element type and necessary number of elements to use in numerical analysis are recommended. According to the results of the para- metric study of the perfect shell, the buckling strength decreases significantly as the diameter- to-thickness ratio increases, while it decreases slightly as the height-to-diameter ratio increases.
