Stresses at the saddle horn of a horizontal vessel on saddle supports

The original calculations of the stresses in a horizontal vessel on saddle supports by L.P. Zick in 1951 made no distinction between vessels lying loose on the saddle and vessels lying on a wear or reinforcement plate, welded or not. However, this has a significant influence on the magnitude of the circumferential combined compression stresses at the horn of the saddle. In this blog derived methods are discussed that do take this into account. Furthermore the conditions are discussed under which each of these methods may be used.
