“…The observations recorded in these experimental studies are essential data to validate the analytically based design papers [4][5][6], which will provide a design methodology that is appropriate for the actual vessels used in practice. …”

“…As an aid to developing an appropriate analysis, which accurately models the actual vessel behaviour, it was considered important to examine experimentally the plastic collapse and buckling phenomena referred to above (modes 3 and 4) with particular reference to the range of R/t values over which they occur. On the basis of this work a theoretical approach has been developed and will be presented in references [4] to [6].…”

The use of plastic analysis in the design of horizontal vessels, used for liquid or gas storage, and supported on twin saddles, allows better utilization of the vessel's material and avoids the problems of categorizing the elastic stresses when designing the component. To understand how the vessel collapses onto the saddle, experiments were conducted on a range of model vessels (40 in all) with different radius-thickness ratios (R/t) and supported on saddles which were either loosely fitted or welded to the vessel. The experimental results show that different collapse mechanisms occurred for loose and welded saddles and also that the modes of failure were dependent upon the value of R/t for the vessel. In general, progressive plastic collapse occurred in those vessels with low values of R/t and elastic-plastic buckling for vessels when higher R/t ratios were employed. This paper presents the detailed experimental results, which are used as the basis of a theoretical design approach; the latter will appear in future papers considering both plastic collapse and buckling failure.

“…The buckling of horizontal cylindrical vessels supported on two saddles were investigated by Chan et al [46]. For the loading patterns that were considered, the buckling behaviour of the vessel was primarily governed by the values of longitudinal and circumferential membrane stresses at the top and bottom locations of the midspan section and the sections through the centre of bearing of the saddles.…”

“…Metal shells are particularly susceptible to buckling on account of their thin-ness (radius-to-thickness ratios typically in excess of 500). Numerical studies have been carried out on the buckling capacity of vertical cylindrical steel tanks [6][7][8][9][10][11], horizontal cylindrical and near-cylindrical vessels [12][13][14] and conical tanks [15][16][17]. The buckling capacity of multi-segmented shells under external water pressurisation has also been investigated [18], as has the elastic buckling of certain unusual mathematical forms for shells [19,20].…”
