DESIGN OF HORIZONTAL VESSELS WITH SADDLE SUPPORTS 

Horizontal vc ssels when resting on saddle supports such as shown in Fig. 11.2 behave as An analysis of 

The maximum unstiffened length of s he ves.sel between t he heads, the ring compression in the slieli over the saddle, the stresses on the ring stiffeners, and the total ht n2onUil force acting against the horns of the saddle may also be determined. 

In selecting the location of saddle supports it is preferable to make dimension A less than dimension R in order to take advantage of the stiffening effect of the head. Dimension A is often selected so that A — OAR. Dimension A should never racceed 20% of dimension L otherwise the stresses resulting from cantilever action will be excessive. 

The weight of the fluid and the vessel may be considered to 1 a uniform load equal to the total weight divided by the equivalent length, or
