“…than 120°. This is in line with the loading cases of most engineering steel shell structures with discrete supports or equipment installation [30,31]. Due to the asymmetry of the cylindrical shells under partial axial compression, changing the relative location of the geometric imperfections to the axial loads will change the shell buckling behaviors.…”

“…In engineering, the actual loading case of steel or alloy cylindrical shells is distinctly more complicated [28,29]-for example, partial axial compression loads. The equipment set up on the top of a shell structure, such as the trestle piers installed on steel silos [30] or the ring cranes placed on top of nuclear containment shells [31], cause the partial distribution of axial compression loads, as shown in Figure 1. Moreover, discretely supported storage silos may bring about large reaction forces around the support column ends, which can make the cylindrical shell prone to buckling.…”

A thin-walled steel cylindrical shell is a common engineering structure that has an efficient load-carrying capacity. This structure is more easily subjected to partial axial compression loads in application, and buckling is the main failure mode. However, there are few available design methods for partial axially compressed steel cylindrical shells. Motivated by this, a design method called the localized perturbation load approach (LPLA) is proposed in this paper. The finite element framework for the application of LPLA is established. The location and number of perturbation loads are determined by considering the imperfection sensitivity and the buckling failure mode of partial axial compressed cylinders. A series of buckling experiments are carried out to validate the LPLA method. In addition, the reliability of LPLA for the design of cylindrical shells with different imperfection locations and dimensions is also verified. The results show that LPLA can give conservative and reliable lower-bound buckling loads. Therefore, LPLA can be used as a design method for thin-walled steel cylindrical shell structures under partial axial compression in actual engineering.

The analytical solutions for buckling of closed and open cylindrical shells under different boundary conditions are challenging. A separation‐of‐variable method with closed‐form eigensolution under Donnell–Mushtari theory is proposed for eigenbuckling analysis in cylindrical shells. The modal function is adopted as the form W = eμαeλβ. It can be applied to the closed and open cylindrical shells with different boundary conditions, and the whole calculation process is explicit. The critical buckling capacities of short cylindrical shells are close under the simply supported or clamped boundary conditions. The predictions are in good agreement with those in literature and the finite element model.

Условия потери устойчивости резервуара при локальной сжимающей нагрузке изучались в работе [10]. Поведение резервуара в связи с осадкой основания рассматривалось в [11,12].…”
