Stresses in Elastically Supported Cylindrical Shells under Wind Load and Foundation Settlement
Thin-walled shell structures of a circular cylindrical shape are widely used in structural engineering to serve in applications such as silos, tanks or chimneys. The design of such structures poses some considerable challenges to structural engineers as the load carrying behaviour of cylindrical shells is quite complex, especially for non-axisymetric load cases. Very often a comprehensive analysis causes considerable expenses and the vast amounts of results which are typically generated make it hard to understand the underlying load-carrying principles of the structure. The introduction of an engineering method to handle two typical non-axisymetric load cases on circular cylindrical thin-walled shell structures is the goal of this paper. The proposed method offers a quick way to generate critical section forces and displacements. The load cases discussed herein are wind-loading and foundation-settlement. Ground support for many cylindrical steel structures is often realised by anchoring the lower shell boundary to a concrete foundation. This is accomplished by steel bolts that can be looked at as spring elements providing elastic support for the shell structure. The influence of this type of support on the section forces and displacements under wind loading can be modelled by combining the two abovementioned load cases via an interaction diagram also given in this paper.
