Pad-reinforced cylindrical shell loaded radially through a plate bracket attachment

Abstract

The constructional detail of a bracket attached to a pad-reinforced cylindrical vessel and subjected to a radial load is studied experimentally. An approximate analysis which is based on experimental observations of the load distribution in the bracket is developed. It allows a complete stress analysis of the reinforcing pad and vessel. Stress distributions determined using this analysis show general agreement with experimental stress distributions. Stress calculations based on the BS1515 method of assessment result in values greater than the measured stresses.

Stresses from radial loads and external moments in spherical pressure vessels

“…Analytical solutions for local displacements and stresses in cylindrical shells with loading over rectangular area were developed by Bijlaard [1][2][3] and other authors [4][5][6][7][8][9][10][11] using double Fourier series and different governing differential equations and models of attachments. However, until the work of Chao [12] this method had never been extended to spherical shells with rectangular attachments, although this type of attachment is often used for lifting and support legs (Fig.…”
